I am designing a plastic cover with a latch and plastic hinge. Is there any online documentation or share ware describing design concepts for snap fits and plastic hinges?
This topic, at least in part, was covered in prior threads. Try the thread thread288-34812: Plastic snap fits on cylindrical components. Try also searching on Google.com.
Best regards,

If you get the CD ROM from Bayer Plastics, it contains a lot of very comprehensive design documents in PDF format, one of which covers the design of latches in plastic.
I designed a similar part a couple years ago. Polypropylene is your best material for a living hinge, although I have heard of people using polyethylene and nylon.
