How a scale model helps envision and sell a gas processing plant.

Posted by Hal Chaffee on Mon, Mar 23, 2015 @ 11:41 AM

UOP had an investor meeting coming up and wanted to make a great impression showing the advantages of their prefabricated gas processing plant. UOP is the only manufacturer that makes a prefab one and it consists primarily of seven skids that can be trucked to the site. They also wanted to use this model for sales presentations and tradeshows. 

The UOP advantages are that the prefab gas processing plant can be made much more cost effectively in advance in a factory and there is little final assembly once the seven skids are shipped to the client's site. Furthermore quality control in the factory is much easier to manage than in the field.  UOP's competitors build  gas processing plants on site which takes far longer and their construction time is much more exposed to weather delays. 

UOP Gasification Plant Model

UOP prefabricated gas processing plant 1:48 scale model 25" long X 25" wide.

To have a real impact with investors and potential clients UOP wanted them to easily envision the prefabrication concept and how it went together. If they could pick up each of the seven skids to assemble or disassemble them by hand that would be very engaging and memorable. Furthermore clients would be able to see the key components in each skid. This is an effective way to relate to what each skid does and where it goes.

The model makes for quicker and easier comprehension of the entire plant than walking through the real one. Furthermore  the real prefabricated gas processing plant is too big to take to a tradeshow (or potential client) and most potential clients are not located near one of the installed prefabricated gas processing plants.

What were the keys to getting this model fabricated to meet UOP's short deadline and to be as effective as possible in generating sales? 

(1) Choose the right model maker.

Hire a professional model making firm with experience - in this case one that makes process models for heavy industry like oil, gas and nuclear models. This firm would know where to get the special materials necessary and have the expertise to help design and fabricate the model in about four weeks. For this model UOP hired Model Builders, Inc. in Chicago.

(2) Provide the information the model maker needs to build from right away.

UOP drawings were needed to build from and they were needed fast. Model Builders, Inc. suggested that only pdfs of some of the drawings were needed.  It would have taken more time and expense if the model maker had to get familar with the UOP CAD drawings since it takes a while (often several days) to get familiar with the many CAD assemblies and parts drawings.

The UOP Director of Corporate Communications recognized that the model maker needed the pdfs right away and put the key UOP engineer in Oklahoma in touch with the model maker. That same day the engineer was able to send out all the needed dimensioned drawings as pdfs.

(3) Choose the scale.

 The 1:48 scale was the right one for an engaging hands on demonstration and for transport in a personal vehicle if necessary. Furthermore a scaled flatbed truck was put on the model to help the viewer get a clearer idea of how big the skids were by comparison.

(4) Determine the level of detail.

One of the things about models is that viewers are often attracted to them when they are highly detailed. The details draw them in. With this model even the UOP designer was impressed with the detail accuracy. This is particularly helpful to the sales effort when UOP can discuss with potential buyers what each skid does and the component parts that do that.

(5) Engage the viewer in creative ways.

UOP had Model Builders, Inc. make the seven skids as loose units that can be assembled and disassembled by hand on a simple base with a plan view of the site on top. That meant each model skid could be picked up by hand and assembled or disassembled in the appropriate location on a scaled drawing. The drawing was bonded to the top of the 1" thick 25" X 25" base board.

The stairway next to the right hand and the crosswalk next to the left finger are each connected with magnets for quick and easy assembly.

 

(6) Use durable materials.

ABS plastic is a very durable material and is the primary material used in this model. Futhermore the bonding liquid chemically welds the parts together.

In contrast acrylic is brittle and sometimes cracks or breaks. Vibrations during shipping and handling, below-zero temperatures and other adverse conditions could cause breakage or the acrylic glue joints could come apart.

(7) Make the model easy to pack and unpack.

The cutouts in the thick foam make packing and protecting the parts from damage simple.

How effective was the model at the investor's meeting? It was so effective UOP decided to order a second one to keep at the home office for potential customer presentations.

Where can you find out about 3D printing of prototypes and models?

Posted by Hal Chaffee on Sat, Mar 29, 2014 @ 10:56 PM

We often have potential clients who are interested in having a prototype or model made with a 3D Printer. However they don't know if 3D printing is the way to build their project better, faster, stronger and at a lower cost. Our experience is that 3D printing can alternatively be not as good, slower, less durable and at a higher cost. It depends on a lot of factors. You need to learn more about 3D printing and it helps to discuss your project with a professional model maker.

Two of the best websites to learn all about 3D printing are www.additive3d.com and www.prototypetoday.com . Those two comprehensive websites give you lots of information on the whole field of 3D printing.

2014 Printing the Future book resized 600

You can also order a informative book "Printing the Future" by Ed Grenda from his website at http://www.additive3d.com/pub_bks.htm .

To get a perspective on 3D printing you should think about it as three categories - 3D printing of prototypes and models, 3D printing of manufactured products and 3D printing for personal fabrication. That is also the order in which those three categories developed.

3D Printing of prototypes and models and 3D Printing of manufactured products

The two largest manufacturers of professional 3D printers are 3Dsystems at www.3dsystems.com and STRATASYS at www.stratasys.com . They make 3D Printers for all three categories of 3D printing. In January, 2014 at the CES show in Las Vegas 3Dsystems had a number of new product announcements and those products are featured on this 54 minute youtube video at http://www.youtube.com/watch?v=UWnmzn1rl8A . It will give you some idea of the range of 3D printing products in the marketplace. NOTE that both 3Dsystems and Stratasys  recently purchased companies that make 3D printers for personal fabrication and more recently created new 3D printers for personal fabrication.

The RAPID show organized by SME (Society of Manufacturing Engineers) is the main conference and tradeshow for companies and institutions to see the vendors of the larger professional 3D printers used for large 3D prints and in metal as well as plastic.

Since the middle 1980's when 3D printing started 3D printers were very expensive so companies and institutions that could afford it bought 3D printers and the CAD (computer-aided design) software so their model shop or an independent professional model shop with the right software and 3D printer could make their prototypes and models. About 7 years ago the least expensive professional 3D printer was about $15,000.00.

3D Printers for personal fabrication

3D Printers for personal fabrication sell mostly fom $400.00 to $5,000.00. There are now over 100 different 3D printers for personal fabrication available. By January, 2009 the first two 3D personal fabricator machines were being sold as kits for about $800.00 each. To get a review of many of these 3D printers for  personal fabrication that are now available see http://www.additive3d.com/3dpr_cht.htm . Also order from MAKE magazine their latest annual review of 3D printers at http://makezine.com/volume/guide-to-3d-printing-2014 which compares 23 of the more popular low end 3D Printers.

Formlabs Form 1 3D Printer

3D Printer for personal fabrication - Form 1 hi resolution 3D printer

However if you buy a 3D Printer you still have to purchase and learn how to use the CAD  software to create the files for the product that you want to 3D print. Alternatively you could use CAD drawings that are available on www.thingiverse.com or similar websites and you can print them. However most people want to create something unique.

There are also companies that can do your 3D printing for you.  One very successful company is Shapeways at www.shapeways.com  .  Shapeways has 3D printers for smaller personal fabrication and also have larger professional machines that can print in plastic or metal. You can even set up your own store on Shapeways to sell what you have made.  They will accept orders for you, produce your printed product, ship it and collect the payment for you.  The Shapeways byline is "Make, Buy and Sell Custom Products with 3D Printing. One store example hosted by Shapeways is www.bathsheba.com  .

Another alternative is to go to a store like the 3D Printer Experience in Chicago at www.the3dprinterexperience.com or a shop like TechShop (a expanding nationwide chain) that sells education classes and charges you to use (or have them use) one of their 3D printers or other machines. To find these places go to the Maker Map at www.themakermap.com , check off the filter box for retail, museums, etc. and zoom in on the red location dot. As you zoom in the name and address, etc. will appear on a pop up.

Then click on what you want to find like Retail and then zoom in on the red dot in the location you prefer and the name, address, etc. will pop up.

Getting the best possible prototype or model

Large corporations often have their own industrial design department and model shop. They can study how users might use a new product and create prototypes to test the idea with potential users. Alternatively they may hire an independent industrial design firm like IDEO which also has a model shop. If you have a large budget then hiring an industrial design firm might be a good option for you.

However the top down process of creating a new product is now competing with the bottoms up process since individuals and smaller companies or institutions now have computers and tools such as person fabricators as well as funding mechanisms like Kickstarter available to help them to create new products at an affordable price.

Hiring a professional model shop to work with you on your prototypes and models should add a new dimension to the discussions and increase the odds of creating a successful product. Working with a professional model shop is often a affordable option. Their expertise will greatly improve the final product. Which is the best way to make your product better, faster, stronger and at a lower cost? 3D printing may or may not be the right answer for how to make your prototype or model.

To make a plant layout model what does the model maker need from you?

Posted by Hal Chaffee on Thu, Jul 18, 2013 @ 06:52 PM

To quote and build a plant layout model the model maker needs information from you. With your answers to the following eight questions you can get a quote and timetable for a plant layout model that best meets your requirements.

1) What do you need a model of?

Does the plant model reprsent one product production line, a number of product lines, a distribution center, a process like an oil refinery with multiple buildings, tanks, piping and other structures? Is it an interior model only or does it include the site outside the building?

Plant engineering studies often use a plant layout model to help analyze different equipment configurations and layouts. An existing or proposed facility may be limited in space and determined by an architectural structure. Equipment models, block or detailed, may be used to represent the different types of equipment. The model equipment depictions can be moved around in the facility until the best layout is determined. In office areas plant layout models help determine how to divide office space and show other floor space options.

Many companies use a physical plant layout model in the process of optimizing the entire plant design including electrical, water, hydraulic and HVAC before construction starts. This engineering model provides a three dimensional view of the current design which acts as a focal point for communication among all of the engineers and other personnel involved.  Normally the model pays for itself by reducing or eliminating misunderstandings, omissions and reducing drawing requirements. 

A plant layout model is particularly helpful where there is a lot of complex piping. The piping can be color coded with industry standard colors to make it quicker to understand. If there are errors in the piping drawings they are discovered when a physical model is made and that saves time and money when the real piping is installed.

Sometimes a plant layout model of a large site is used to explain a process like water treatment to customers or the public so they can more easily visualize all of the buildings and tanks as well as their interrelationship. 

 2) What is the purpose of the model?

 If the model maker knows the purpose of the model you may get suggestions that improve the model to better achieve the purpose. For instance arrows on the equipment or floor may help in clarifying the direction of travel in the production line.

-Production line with arrows

Conveyor direction of travel shown with arrows 

- Are you building a new production line and using the model to figure out an optimal equipment layout?

- Is the plant layout model for production training in a manufacturing plant?

- Is the model to give an overall view of a large production area to show potential customers?

- Is it a focal point for employee quality meetings?

- Is it a plant layout model for planning changes in the production line?

- Perhaps the model is to explain the best design features to your workers, managers or clients.

Let the model maker know the purpose and what is important to highlight on the model.

3) What is the scale?

You may or may not have figured out how big you want the model.  We find it quite helpful if the potential client has already printed out a plan view and some elevation views of the model in the scale they think they want it.  They may find some important details such as control panels, piping or handles are too small in the model scale they originally thought they wanted. We have noticed that a number of clients need to see the printed out views before they can be sure it is in the right scale for their use.

Common scales for plant layout models are 1:48, 1:100 and 1:200.  A lot of model structural parts, materials, architectural parts, vehicles, people, landscape detail, etc. is available in those scales. It often helps to have a scale person(s) or vehicle(s) in the model to make it easier to understand visually the model scale.

If there are railroad tracks in the model it is much less expensive if the model is in a standard railroad hobby scale.  1:87 scale is HO gauge which is the most popular railroad gauge, 1:160 is N gauge. and 1:220 is Z gauge. For larger scales track exists. 1:48 scale is O gauge and 1:24 scale is American gauge. Tracks in a few other large gauges exist. A lot of plant layout models are 1:100 scale which is close enough to HO gauge that HO gauge railroad tracks, railroad cars, vehicles, people and cars are often used in 1:100 scale models.

4) Do  you have drawings and if so in what format?

 Model cost estimates should be based on requirements that are well thought out before the fabrication of the model begins. To get a model quote it is helpful to have at a minimum pdfs or alternatively printouts in the desired model scale with plan and elevation views. A common CAD file format is .dwg or .dxf. but many other common CAD formats can be used. Photographs of the plant and equipment are also quite helpful in determining the quote.

If not available at the quote phase then before model fabrications begins the model maker needs any detailed drawings that may be available.  If you do not have a complete set of drawings it is helpful to provide a list of what is missing. The drawings should also be reviewed prior to giving them to the model maker to be sure that there are no earlier obsolete drawings included or obsolete file types like .CAL files.  We have seen projects where the quote had to be revised by up to 40 percent more because 400 out of about 1,000 drawings were obsolete earlier versions of the same drawing, were not needed to build the model or were missing.

5) Do you need explanatory labels, diagrams or lights?

A control board with labels on the side of the model could also light up specific machines, areas or builidngs in the model. Chase lights could be added to show the flow of a production process. See our earlier blog on a plant layout model with a control board and lights at http://modelbuilders.net/blog/bid/154286/This-waste-water-treatment-plant-layout-model-shows-how-it-works .

6) What type of base do you need? Do you need a clear plastic dust cover? Do you need a shipping crate or case?

Models larger than 4' wide X 8' long are often made on multiple tables that butt up and line up with adjacent tables on one or more sides. If the model  is 4' X 8' or less then often the base is about 4" high wood that frames all four sides. Removable legs or a credenza style base underneath (with or without doors) could be added under the wood framed model.

A clear plastic dust cover is not used very often on a base that is bigger than 4' wide X 8' long. Usually a clear plastic barrier would be put on the sides instead. Although clear acrylic does come in 5' X 10' sheets it tends to bow downward on the top of the dust cover in that size.

Some plant layout models could be 2' X 3' or smaller.  For smaller models a ATA style shipping case could be used if desired. Larger models may need to be shipped in a wood crate, customized packaging or a dedicated van or truck. It is usually best to have the model maker, who knows best where the model might need extra protection or support, produce the shipping container.

7) What is your budget?

The price of a plant  layout model depends on a variety of choices that are to a large measure determined by your budget. The scale of the model, the number of parts, the level of detail and many other factors determine the final price. You can save yourself and the model maker a lot of time by defining a price range or maximum at the start of your conversation. Then discuss which of the choices will reduce or raise the price. Block depicted equipment is less expensive than detailed equipment for example.

Block depicted equipment in a manufacturing plant model

There are three major steps in making a plant layout model.  They are design, planning and fabrication. If you have thought through a lot of the design and planning as well as provide drawings, illustrations or pictures, etc. of what you want then the price will be lower than it would otherwise.  

8) Who will the model maker be working with on clarifying the marketing and technical details?

The model maker needs to talk with the person or persons who can provide the best and quickest answers to marketing and technical questions during the planning process. That cuts costs by improving the model maker's ability to prepare an accurate quote at the outset rather than dealing with additional work orders.  If you provide the essential information during the quote process the model maker does not have to add to the quote a figure to research the answers to vague or incomplete information.

The final model is often best if it is a collaborative effort between you and the model maker.  Model Builders, Inc. is known for creative, economical, realistic plant layout  models. Take the next step by contacting us at Model Builders, Inc., 773-586-6500 or info@modelbuilders.net .

Props and models help to attract potential clients to your booth

Posted by Hal Chaffee on Thu, Jun 27, 2013 @ 09:29 PM

Props and models can be a great way to attract visitors at a tradeshow. However they should be related closely to a company's marketing and sales message.  You want to attact people who are interested in your product and help others who are not viable prospects realize that this product doesn't relate to them.

Here are four examples where props and models have attracted potential clients.

1) The first example is where the product is the center piece of the exhibit and also a beacon that is visible from a distance.

Far better than just a sign the model is of the product being sold. If you are interested in cell towers then you are not likely to miss stopping by this booth and learning more.

This cell phone antenna model is used at  tradeshows to attact potential clients to the booth. A red light on the top also helps to get attention. The height of this model makes it noticable on the tradeshow floor from quite a distance away.

2) The second example is a custom three dimensional model sign that attacts attention with movement and light as well as relating well to the product.

Below is one of two rotating signs for the Global Sleep Solutions tradeshow booth. There is also below this sign in the booth at eye level a similar but larger sign (one sided) with three Z s in a row on one rod that slowly rock up and down which effectively reminds you of sleep.

Two of the most effective ways to attact attention are to use movement and/or light. This rotating sign uses both movement and light. Furthermore the lettering is large enough and words short enough to be easily read from a distance. The crescent moon and large Z letters let you know in a glance that this booth is about nightime sleep solutions. The sign rotates at a sleepy 2 rpm.

3) The third example is a larger than life product model and it also uses light to draw in visitors. This toothbrush gets instant attention at tradeshows because it is several times larger than life, it looks realistic and the lighted fiberoptic bristles draw the viewer in for a closer look.

4) Food tends to be a product category that gets a lot of interest. One tradeshow exhibitor who sells signs related to food decided to have a custom 6 foot long "Chicago" hotdog made so he could use it as the centerpiece in his booth to attract attention to his food signs.

Construction equipment product models increase sales and cut costs

Posted by Hal Chaffee on Wed, May 15, 2013 @ 10:33 AM

There is nothing like demonstrating a real product at a tradeshow or event.  However if you are selling a large piece of construction equipment it may be too large or too expensive to do that. Consequently some construction equipment companies are using a custom model that will fit into an exhibit booth or is easily moved to a customer's office for a sales presentation.

Showing a construction equipment model at a work site such as on a railroad track can help the potential customer better relate to how the equipment is used.

Features of the equipment can be depicted. This 1:16 scale mining truck shows that the electrical equipment is concentrated in one place in a three door cabinet on the deck next to the driver's cab so that it is easy to access and fix. Using a control on the side of the model base the sales person can turn the front wheels to show that this truck behind the wheels has the most accessible engine for maintenance (there is a scale engine between the front wheels). Also the dump bed can also be raised and lowered (by turning a key) to attract attention at the tradeshow.

In 1956 a 1/4 scale model of the Hough Payloader attracted crowds at tradeshows because it duplicaticated the hydraulic actions of the real front-end loader by using miniature cylinders and a new reversible pump unit. Automatic or manual operation was selected by the 4-pole transfer switch. In automatic operation limit switches control direction of current flow through armature and direction of motor control. In manual operation current flow was controlled by momentary pushbutton switches. This model was written up on two pages of the December 1956 edition of Applied Hydraulics magazine.

Use product models like those described above to help the product sell itself and grab the attention of potential customers at a trade show or on a sales call. Give yourself a competitive edge with a product model that tells your product’s story with impact and often without the use of words.

A construction equipment product model enables you to show your product in more places and at less cost than if you took the real product. Take the next step by contacting us at Model Builders, Inc., 773.586.6500 or info@modelbuilders.net .

Why do industrial designers use a model maker?

Posted by Hal Chaffee on Mon, Mar 04, 2013 @ 10:39 PM

Industrial designers hire a model shop or use an in-house model shop to build physical prototypes of new products and other ideas. Knowledge of prototyping, materials and manufacturing techniques enable the model maker to refine an idea from two dimensions into a physical model that turns that idea into a product.

Here are 8 reasons why industrial designers use model shops:

1) Reality. As stated on page 132 in the 1947 book "Design for Business" by J. Gordon Lippincott

  "Before any design goes into mass production, a full scale model should be made and, if at all feasible, an operating model.  The costs of tooling, merchandising and advertising are so great that any economies gained by skipping the model-making step are more than offset by the greater risk of producing an article that lacks consumer acceptance through failures in styling or function.

Renderings are particularly misleading and should serve only the function of stimulating new, fresh, creative thinking.  In other words renderings are only the expressions of the idea stage.  As soon as a proposed form for a new product has been selected, models should be produced - in full scale wherever possible or practical. Half and quarter-scale models are completely misleading because most people do not have the ability to appreciate changes in scale.  A molding on a quarter-scale model of a refrigerator may look perfectly satisfactory, but when the same design is enlarged to full scale, the molding will be completely out of proportion  - usually too large."

2) Capability. The industrial designer usually needs a model maker that has a shop with a variety of capabilities including machining, rapid prototyping, woodworking and finishing work such as sanding and painting. The space, machinery and model making talent needed to produce the industrial designer's prototypes and appearance models are simply too expensive to do at the industrial designer's location unless there is a constant volume of work to do.

The larger industrial design firms like IDEO and large companies like Steelcase tend to have an in-house model shop to create prototypes and appearance models. However for peak loads of work, special expertise or equipment, and a short run of parts they may use an independent model shop.

3) Expertise in materials. Professional model makers know from practical experience what materials may best meet the demands of the designer's intentions and the conditions a product will face.

4) Speed. Initial prototypes may be quicker if made in thin acrylic or styrene with vacuum forming.  Rapid prototyping is also used to create quick prototypes once the computer CAD work is done.  Machining plastic or metal is often the best way to create the final model since there usually can be much finer detail, more durable material and less finishing work. 

5) Product development. The initial design is tested with potential customers to see how well the product design works. Sometimes the product when held doesn't feel balanced. Many prototypes may have to be built and tested sequentially with changes before the product is ready to sell in the marketplace. Design is a collaborative process and model makers help the industrial designer perfect his craft.

6) Appearance. A passion to do finishing work, the right grit of sandpaper, the right primer, the right shade of paint, a gloss, semi-gloss or flat finish often determine the success of a new product. The texture and finish must be the same as the final product. We hired one model maker because he could produce a flawless high gloss black finish on a wood base 10" high X 48" X 96". Sometimes industrial designers specify a specific model maker because of his or her superior finishing work.

7) Testing. Sometimes a design looks good on paper but doesn't work right when a prototype is built. The best model makers have the mechanical and electrial skills to help solve those problems.

8) Imagination. You never know when someone else's imagination, expertise, experience or knowledge may improve a product design. Model makers at in-house shop usually have a great knowledge of a particular product's history and techniques that were used to make that type of product.

Independent model shops often have a broad range of experience and may bring in new ideas from their diverse experiences.  At our independent model shop we sometimes find ourselves delving into a dusty two volume set of books titled "Ingenious Mechanisms For Designers and Inventors" that was first published in 1930 with chapter titles like "Intermittent Motion" to create special mechanical motions for a new product. Mechanisms in this book have already passed two important tests - (1) these are designs of mechanisms that will function properly and (2) they are simplified designs which normally are less costly to manufacture and more durable. This is just one example of the resources and experiences that model makers have. Last week we found a new nanotechnology based consumer product that removes and then prevents fingerprints on stainless steel.

Museum model of ARAMCO oil rig 7' high is a Saudi highlight

Posted by Hal Chaffee on Fri, Jan 04, 2013 @ 05:44 PM

The Saudi Aramco Exhibit is in a high-tech museum near Saudi Aramco's headquarters in Dhahran and is dedicated to energy education. There are 8 permanent sections to find out about oil production, Saudi Aramco's history and Arab-Islamic history. Also included are many temporary exhibits. Important information is combined with fun for youngsters and the family as well. There is a 3-D film "Energy to the World", a variety of ingenious hands on displays and interactive computer games to involve, intrigue and educate visitors. Every year the exhibit attracts tens of thousands of school children and international visitors.

The Saudi Aramco Exhibit opened in 1987. It features three dimensional models such as the 7' high detailed oil rig model shown below. 

Oil was first discovered in Saudi Arabia in 1938 and ARAMCO later became the largest oil producer in the world. The exhibit dramatically tells the story of the petroleum industry and relates it to over 10 centuries of Islam (from the 7th to the 17th Century) technological advances and heritage. By the mid-ninth Century Arabic had become the international language of scientific thought.

Recently a National Geographic book "1001 Inventions - The Enduring Legacy of Muslim Civilization" (now in its Third Editon) and a traveling exhibition "1001 Inventions" (originally opening in the United Kingdom in 2006) has exposed millions of people to the Muslim technological advances and heritage. Currently the "1001 Inventions" exhibition is at the National Geographic Society in Washington, DC until February 3, 2013. We like to think "1001 Inventions" exhibit is based on the pioneering ARAMCO Exhibit that opened in 1987.

Oil Rig model 8' high

This 7' high oil rig model scale is 1/2"=1'-0" or 1:24. The model is in a scale that people can relate to and easily comprehend the entire oil rig as well as the details.

Oil Rig Model - Hook

Oil Rig Model - Traveling Block, Hook and Swivel

Visitors are inherently attracted to a highly detailed model such as this oil rig that looks realistic. The traveling block and hook above are part of the hoisting system. Below them is the swivel which is part of the equipment that rotates the drill. This is a Loffland Brothers Rotary Rig. 

The model is all brass construction that is silver soldered into a very strong welded bond that enables this fine level of model detail as well as durabilty. It will withstand exposure to extreme temperatures if it is ever displayed outdoors or transported in a vehicle that is not air conditioned. 

Oil Rig Model - Monkeyboard

Oil Rig Model - Monkeyboard

Fine detail like the monkeyboard platform is possible with the strong silver solder welding of the brass. The monkey board is used as the oil rig man’s work platform. The monkey board is located at a particular height in the derrick or mast. It is the same height as single, double or triple pipes.

Oil Rig Model Mud Return Line

Oil Rig Model - Crown Block

The crown block is a fixed set of pulleys (called sheaves) located at the top of the oil rig mast over which the drilling cable is threaded. The companion blocks to these pulleys are the traveling blocks. By using two sets of blocks a great mechanical advantage is gained. Consequently small steel drilling cable (3/4" to 1-1/2" diameter) can be used to hoist loads many times heavier than the cable could support as a single strand.

Colorful museum catalogs at the entrance (according to the Saudi Aramco World magaine November/December 1992 issue) go right to the point of the Exhibit that "it is meant to be a place for joyful learning...a carvansary for the curious" revealing secrets about the past, present and the juxtaposition of the two".

Nuclear training models improve safety

Posted by Hal Chaffee on Tue, Nov 06, 2012 @ 10:34 PM

Nuclear training models can be very effective in improving safety and reducing radiation exposure. These training models are often of a nuclear steam generator, a nuclear condensor, a nuclear reactor or even a nuclear plant site.  

The models are a focal point of planning and training discussions.  They provide a clear understanding of the entire process and the specific details of the parts and areas where workers will be doing upgrades, repairs and maintenance.

The Nuclear Regulatory Commission (NRC) rates each nuclear plant on radiation (rad) exposure. Training in advance of going into areas where an employee can be exposed to radiation normally shortens the amount of time they are there.  This helps employee safety and minimizes rad exposure for meeting NRC requirements.

Nuclear Steam Generator model

Nuclear Steam Generator training model 48" high (1:16 scale) with intuitive diagram

The nuclear steam generator shown above is a highly detailed training model used at Calvert Cliffs Nuclear Power Plant in Maryland. There are many features in this new model that improved training compared to the use of a prior model that had not yet been upgraded. Instead of numbers on the model and a list of numbers with the name of each part next to the model this new model uses the intuitive diagram just below the above pictured model to correlate (with black lines) the part name to the part in the model. It also uses red (hot) and blue (cold) arrows to show the process flow of the water and steam. Comprehension of how the steam generator works is quick using this cutaway model and its intuitive diagram.

 Cutaway View of Primary and Secondary Dryers

Primary and Secondary Steam Dryers

Above is a cutaway view of the primary (blue tubes) and above them the secondary dryers (in white) to show where the steam flows. The output from the steam generator is dry steam which goes out from the top of the steam generator and then into the turbine which generates electricity.

Manway Cover

The lower half of the steam generator model shows tube bundles (containing hot water) in lattice grid assemblies and one of the manways (with the bolts) in the middle. Every bolt on the manway covers and every latch on the hatch doors is shown on the model which is important as there is a specific sequence that should be used when opening each one.

For more information on this and other nuclear models please reference a 5 page interview titled "Bill Baines: On the use of steam generator modeling at Calvert Cliffs" in the April, 2003 issue of Nuclear News magazine published by the American Nuclear Society (ANS). Go to this link docs/2003-04-01-NuclearNews-SteamGeneratorModel-ModelBuildersInc.pdf .  

Calvert Cliffs also has a scale model of their reactor vessel and its internals.  Bill Baines, the program administrator for the Engineering training program, oversees the initial and continuing training of about 180 engineers and analysts at the plant.

In the U.S. nearly 20% of power comes from 104 reactors which were mostly built between 1967-1987. Upgrades to existing equipment such as to the two Calvert Cliffs steam generators are where scale models are used for planning meetings as well as for training. The models allow everyone to see how the old and the new steam generators differ and what the workers could expect to encounter.The models provide project personnel with a visual 3-D model that shows how components might interfere with each other during removal and installation.

The US Department of Energy and some nuclear plants are also using a site model for planning and reviewing security procedures on a regular basis. Communication is easier when everyone is looking at the entire area being discussed.

3 advantages of a product model versus the real product in an exhibit

Posted by Hal Chaffee on Tue, May 29, 2012 @ 08:35 PM

One of the easiest things to use to attact visitors to your exhibit booth is your product  because that is what you are selling. However you may be overlooking the advantages of using a product model instead.  Here are three examples of exhibits where there was a very significant advantage to using a product model versus the real product.

(1) The first advantage is a savings in weight and therefore cost. Below is a photograph of a replica model of a track welding machine which is 12' X 4' X 3'.  The cost to ship the real machine which weighs close to 15,000 lbs. is quite high. Then the expense to move a real track welding machine into the exhibit booth and set it up is also high. However a replica model made out of ABS plastic instead of steel like the real product weighed less than 1,000 lbs. The shipping cost savings for the first tradeshow alone can pay for the model.

product model

(2) The second advantage of a product model versus the real product is you can make a large real product as a much smaller product model which enables you to ship the product model to more tradeshows for the same cost as one tradeshow. Furthermore for really large products like some mining trucks the real product is too big to even fit in an exhibit hall.  Shown below at 1:16 scale is a mining truck model which is about 33" long which has been shipped to tradeshows around the world.

product model

 (3) The third advantage of a product model is that an expensive product such as medical equipment with expensive components can be replaced by a product model greatly reducing the cost of shipping insurance. The model cost about 1/15 the cost of the real  lithotriper.The lithotripter model shown below also was made at 1:3 scale to make it small enough for the sales force to drive it to their clients locations in addition to the use of the model at tradeshows. The mechanical arm moved exactly like the real lithotripter.

The benefits of product models are real. If you would like information on having a product model fabricated contact us at Model Builders, Inc. 773-586-6500 or info@modelbuilders.net .

5 ways product models can increase sales

Posted by Hal Chaffee on Fri, Apr 06, 2012 @ 12:59 PM

Product models are an investment that often pays off big by increasing product sales. Here are five ways that product models boost results.

1) Product models attract attention to sales presentations by communicating in three dimensions.  Models tell a story your client can see immediately, even without words. The visual story combined with your comments have a powerful, long-lasting impact. Perhaps my father, William H. Chaffee, a model maker for most of the 20th century, said it best: "Models enable you to visualize an idea or product in a scale you can relate to."

2) Product models are used to draw people into a trade show booth and start the sales conversation. They are an attention-getting focal point in the sales process.  Just changing the scale of a product can command attention.  Small objects become gigantic and large objects can become small enough to fit in a 10' wide trade show booth. A 7' high detailer motorized brush as shown in the above picture, 8' tall drill bit, a 9' long windshield wiper blade with some new features, and a 6' tall toothbrush with lighted fiber optic bristles drew heavy traffic into their exhibit booths. Ordinary products command attention when produced in an unexpected scale and their unique benefits are immediately obvious.

3) "New" is one of the most response-generating words in advertising. Models can get new products in front of customers immediately through quick fabrication for presentations at a sales meeting, trade show, or photography for public relations releases. Prior to the first production run of a new industrial pool pump, a full scale exterior model was built for a trade show to introduce the product. The model was detailed down to the surface which had a casting texture painted on it. When the original product engineers first saw the model, some of them thought the model had come straight from the production line. Without the product model the company could only have shown two dimensional photographs or drawings with less impact.

product models, product cutaways

4) Models can highlight product advantages by showing how the product works or revealing certain features. A cutaway model of a real product can show any unique feature and the quality of the materials used inside.  For example, one product model used a clear plastic housing and some internal translucent parts combined with some real parts to create a jet engine oil pump that revealed where the oil flowed and the unique parts that made it work. For another client, a 2X scale oven with 2" wide red/orange fluorescent plastic "heat arrows" inside showed the even flow of heat.

5) Closing a sale is often quicker when you use a  model. For exmple a scale model of a trade show exhibit booth can sell the client on the booth design. Clients often cannot visualize a 3-D booth design as well as the designer. A model facilitates communication and clarifies any changes to the trade show booth design in order to gain a commitment to go ahead with construction of the booth. A model quickly and clearly shows the interior design, space planning, sight lines, traffic patterns, engineering, materials, colors, signage, and the interrelationships between various elements. The model helps to answer questions and solve potential problems. It is a fast way to understand a complex project and hence shorten the sales cycle.

Done artfully and with skill, product models like those described above help increase sales. Take the next step by contacting us at Model Builders, Inc., 773.586.6500 or info@modelbuilders.net .
