Guidance on Epoxy molds
(OP)
We have purchased an Arburg ALlrounder 35 ton injection machine, old but in beautiful shape. It has a MUD set (modular tool setup) so quick change with smaller subtools make this ideal for us. What I want to do is make a unit tool (basically a bath-tub for the epoxy) for epoxy molds. We do a lot of experimental work making sensors, so its smaller bits and pieces. I can make one of anything on our old Grizzly lathe and mill (dont ask for three identical parts) so I am hoping we can get a few good shots per epoxy mold. Any guidance out there on the use of epoxy molds? Decreased expectations on quality? Can we get a decent surface on the part? I think our largest piece would be only a couple of inches across.






RE: Guidance on Epoxy molds
I have seen excellent results from epoxy moulds inserted into bolsters, with up to 100 shots from the inserts.
The material was Cellulose Propionate in spectacle frames.
Higher temperatures or higher injection pressures may give poor results. I would not try it for PC or GF nylon 66 fr instance.
