I do a lot of die cutting of 1"x6" HDPE plastic about 60 mills thick. I want to try and cut 5 to 10 pieces out at a time and need to design a multiple die and press. How do I determine the force needed to cut the pieces? I am thinking that a "clicker press" would work but I need to know how much force I need.
For an approximate guage, multiply the circumference of the hole by the thickness of the material and multiply that by the absolute tensile strength of the material. For example:
.5 inch dia. hole in .062 inch PVC sheet with a tensile strength of 5000 psi.
punching force in lbs = .5 * 3.14159 * .062 * 5000 = 486 lbs
