how to make a plastic hinge

Tom,

You're talking millimeters,, right ???

By plate, do you mean injection molded box of some type ????

Polypropylene, and polyethylene are the two best materials for a living hinge (polypro being better IMO). There's a few tricks involved both from the design, and proccess ends.

Could you be a little more specific ???

Meanwhile, here's a link (thanks to Bing at AMC) with some pretty good design info.
