Could anyone please give me a website that lists some of the KEMA requirements for the 3mm gap creep distance. Thanks

I curently have an ABS that is not performing well strength wise, and I am considering going to either a long fiber abs or even a long fiber polyester. The original material I used in this aplication was 33%GFN, and the warpage of this curved plastic part was unbearable. I was told that the...

Ivo, Try Delrin. It's similar to nylon in strength characteristics, and is very wear resistant (used for gears alot) http://www.dupont.com/enggpolymers/english/products/delrin.html

Ivek, In order to answer your question, we would have to know the functionality of the existing nylon piece in order to determine if we could use different types of plastics. What attributes should this piece achieve? Wear Heat Strength Contamination Impact Resistance etc..

The clamping force of the bolt also has a lot to do with the type of thread you are using (pitch or lead of the thread) and included angle of the thread profile. This calculation (in one form or another)is in probably all machine design textbooks ever written. Friction coefficients are also...

Do you have any info as far as where I can order this material (with a short lead time....of course).

I'm in the process of prototyping a part that will eventually be made in 380 Die Casting Aluminum. I will do some strength and endurance testing with this material and the best match I have found as far as surface hardness and yield strength is 6061 T4. Nobody seems to have this material...

It is a "flat" base plate that acts as a wear pad for a machine that operates (slides) mainly on wood. Flatness is the most important characteristic, followed by various concentricity call-outs. The warping, and shrinkage is not being controlled by the molder. I realize that the...

I'm looking for a replacement for Durez 31906 Black phenolic. My problem is the lack of dimensional stability, and wear resistance after molding - both of which I have to improve. I'm willing to look at other phenolics, or even other MATERIALS all together. Thanks for any suggestions!

Is there a forum in the Internet that has shareware for different programs in Tk Solver. Or is it possible to share programs on this site??
