I need to die cut small rectangles approximatley 6mm x 4mm out of 1/16 and 1/8 thick plastic and fiberglass sheet. We need to do at least several rectangles at a time. Having virtually no experience in designing dies, I spent about 10 minutes cooking up this design. Would something like this work? Can anybody lend any design advise for a rectanglular die?
