Clipping design standard for plastic case (PP)
Clipping design standard for plastic case (PP)
(OP)
Hello,
I am currently working on a 3D design of some kind of plastic case. This case comprise a top and bottom part which are clipped together.
Our partners want to change the current material to PP (I am not a material guy at all) and told us that since PP is quite soft plastic, we would need to re-design the clipping method.
Some standard exists for that apparently but I cannot find anything relevant on internet.
Can someone is aware of where I could get such information?
Thanks!

RE: Clipping design standard for plastic case (PP)
However, concern about the alleged 'softness' of PP suggests that maybe you are talking about a 'snap fit', where the ramp, spring, hook and latch type details are all molded as part of the case components, so there would still be just two part numbers.
Since you have told us nothing about the current parts, including size and material, that's probably all the help I'll be able to offer.

I guess language might be an issue, but the OP was so lacking in required detail irregardless of language I just did not bother to start playing 20 questions to extract what should have been in the OP.
OP
If it is indeed a snap fit. Many PP raw material manufacturers publish intricate detail on snap fit design.

What I am looking for is indeed a snap-fit. Problem with my post lacking details and so on is that this is totally not my field. I didn't wanted to described too much in the OP because as patprimmer said language might be an issue and my explanations would have certainly not been understood
But now I at least know how this kind of feature is called and I have more elements to continue my researches.

Maybe you can send me screenshot of the product and I can give you my feedback.

Certainly Ticona and DuPont do. I very strongly suspect Bayer and BASF do. I would be astounded if whatever Shell (Lynden Basel?) is called now and Sabic do not
