What Where and How of Metal Shims

What, Where, and How of Shims and Shim Packs

I am excited about our new Free 3D CAD Models ordering service on Rentapen’s web site.  I know I promised to talk more about the simple weld fixture (weld jig), this week,  however I am delaying that because this is (I think) so COOL!!

Our line of tooling components are now even easier to use.   I invite you to play with this new 3d model downloading service.  These files are Free!  Since we are still discovering kinks, be sure to let us know if you find any problems.

The videos I have for you today are about how to use this service.  But there is so much more to learn. These videos aren’t polished, but you will get the idea.

First, I talk about shims and show how they are placed in a real fixture. You might want to turn the volume down a bit, I start in the shop…

I know I go on and on about shims at times. I am a big advocate for shimming in weld fixtures.

With so many variables involved in how much heat will be created during welding and therefore, how much distorting will occur on the product being welded, shims and shim packs are essential. They help the production group set up the fixture before full production begins. So that when the weld jig or fixture goes into full production it is putting out a product that works.

In this next video I  show you how to download a file for a RAPid Block(TM) and a RAPid Riser(TM).

And in THIS video, our team member, Kory, tells you how to get your Pro/E parameters into your STEP file.


I hope you have fun trying out the new 3d models and seeing how you can use them. I’d love to see what you come up with! Didn’t you like playing with legos??

How to Create a Better Weld Fixture, Save Time and Money, Without Leaving Your Chair

Rentapen Inc., located In Waukesha, WI has added a brand new free service to their website.

Rentapen is proudly introducing their 3D CAD Models. The 3D Models will be the new American standard for the Machine Designing Industry. Rentapen’s new 3D models will change how Machine Design Engineers and CAD Drafters design their weld fixtures for the better. The 3D Models will greatly reduce machine design time.

Machine Design Engineers and CAD Drafters from the U.S. will now be able to go on to Rentapen’s website and perform quick and easy steps to make a better weld fixture that will save them time and money without having to leave their chair.

The components are used in fixtures to help locate and hold the product that is being welded or assembled.

3D Models can be altered to meet your needs. For instance, RAPid Blocks™ can be ordered with only holes in one end. In the past, customers would buy the RAPid Block™ and then have to put it in their CNC or take it to another vendor to place a hole in it to hold a locating pin or a rest pad. Now Rentapen does it all. Saving costs, time, and hassles for manufacturers.

All of Rentapen’s RAPid Tooling Components™ are made in the U.S.A. This is in line with Rentapen’s vision as the U.S. Leader in machine design and tooling components.

“We have adopted the RAPid Tooling Components to design and build with because of the flexibility, durability and extreme repeatability that they allow us to have in the areas that require quick accurate dial-in,” said Don, tooling manager at one of Rentapen’s long term customers.

“Rentapen earns their customer’s enthusiasm because we enjoy the opportunity to provide efficiency by design, expertise, and very convenient service,” said Susan Straley, President of Rentapen Inc.

Rentapen is dedicated to reducing costs for manufacturers. And their new free 3D service will greatly help manufacturers continue on their lean journey.

“We are very proud to provide this time and cost reducing service. We invite machine designers to come play with it and let us know what you think!” said Straley.

Weld Fixture Design – Discover how to Adjust Location of Straight Action Clamp

Discover how to adjust the location of a straight line action clamp.

Often times, when designing a fixture we need to think ahead to where else adjustments might be made that will affect the area of the design we are working on.

In this video lesson we discuss using RAPid Plate ™ RB09 in combination with metal shims and over-sized holes to locate a straight line action clamp sub assembly.

So in this lesson we talked about sub assemblies. We have found them very useful.  In a future blog I will talk about how to create them, use them, and still have your whole BOM shown on the main assembly drawing.

Now, those of you who read this blog have a special treat.  Rentapen has just launched it’s beta for downloading 3D models of RAPid Tooling Components.   Please help us test it out and leave a comment below.
