Hi guys, I need to make a die/device to pierce 40mm diameter round hole through woven laminated PE sheet/tarp, this stuff looks like the material plastic bales sacks are made of, but with extra laminated layer that prevent it from unwove.
the thickness is 0.18mm and preferably I would like to punch two layers at once as the product is a sleeve.
Need to make about 20,000 holes or so, for low production rate with a man standing next to the machine.
Basically I thought of making a rule die/or turning punch in that basic design, and use pneumatic cylinder to drive the punch over a backing plate.
Now I have zero experience with rule dies, I did some quick testing with some punch I made on no real design basis
and tested on shop press, now while it cut the sheet the force require seems to destroy the backing plate quite fast, I tried with plywood , some unknown rubber but I guess 90 shore area, Teflon sheet and some pe soft sheet.
So my questions, is it a feasible process for such operation?, if so what geometry/ or recommended rule to use (if it can be installed in such small diameter, and what backing material to try?
