We talk alot about designing adjustment with steel shim packs in weld fixtures. Why?

Watch this slide show. It explains how Rentapen’s RAPid Blocks are used to fine tune adjust a sub assembly. I would like to hear from you why YOU think it is important.

I am sure you may think of many other reasons than those I give below the slide show. Visit me on Linkedin and leave a comment. Or join the discussion on our Facebook Page!

1) Because it makes a better welded product! The product fits within the tolerance specifications and therefore the welded parts fit within the whole product according to the design.

2) Because it allows, during the weld fixture testing phase, to quickly make a change. This is helpful when the customer is standing looking over your shoulder! Instead of saying, “Whoopsy, it doesn’t fit right. We’ll re-machine some parts and you can come back tomorrow or next week.” Instead we can say, “Whoopsy it doesn’t fit right. Go get a cup of coffee while we make a small adjustment and it should be just right.”

3) We can design our fixture for the nominal dimensions of the production parts to be welded together. But what if the production parts are created .005 off from nominal. Now we may have to force the production part into the fixture, or it might not go onto the locating pins at all! With shim adjustability, those little differences that still meet the goals for the production parts, can be accounted for in the fixture.


We are still raising funds for a veteran and colleague who has been hit hard by mitochondrial disease. Check it out! Times are tough for him and his family, even though he is disabled, Social Security Assistance still hasn’t granted him help.

The money we have raised has helped him receive alternative treatments that have helped him gain back some of his mobility and independence. Thanks to everyone who has given so far!!

’til next time,

The Queen
