Looking for some ideas on a little hypothetical issue.........
If I wanted to make a few hundred plastic parts per year like those at
the following links:
I'm pretty sure the plastic is UPVC. Its around 1.2mm thick.
1) Turn up some quick dies from some mild steel scrap.
2) Use a porta-power or 2 ton arbor press to punch out the sheets as
circles and then re-punch as an annulus.
3) Machine up some dies in steel or aluminum.
4) Press form them to shape.
I'm not too fussed about the 3 small bosses - I can just drill those
holes later on.
Am I dreaming to think I might be able to get a nice clean edge and get
them to form nicely when pressed? I can buy them at $6 per unit but if I
could make them for $2 I might be able to earn a few dollars.
