Snap fit calculation

[saravanans_87]

Guys.


I am in the process of designing snap-fit (plastics).


Any help from u guys to start .(any formula or any design guides would be really helpful).


Thanks.

I do strongly advise you to check BASF, BAYER and DUPONT web pages.

Search them through for appropriate tutorials, there are plenty of them. Aside I will try to check my own library to upload something.

I have been designing this kind of snap fits for some time. Beside the
useful inputs that come from pretty much every supplier of compounds
and what you may find on internet by yourself, the basic principle is to
allow the mating parts to deform within the linear field of the material.
This would require some thorough FEM analysis.

I cant find any on the BASF, BAYER and DUPONT.


What i did is just google it. Then i open the home pages of those and search for Snap fit. Nothing comes up ??..


kgwmu,


Thanks. (Anyhow i already have this link).


gromanetto : Yup thats rite.. I need to do fem too. But first i need to find the correct way to design the snap.


Any advice on this topic would be great.

Use this link. It is a BASF Plastics snap-fit design manual. Great information for everything you need.

Some excellent guides here.I love designing snap fits to solve many assy problems..
