I added Tap Plastics Super Pigment so I could better see the surface.http://www.tapplastics.com/product/fiberglass/resin_fillers_dyes/tap_super_pigment/49
No, that would be too much pressure for epoxy molds. However, epoxy molds can work with the Model 150A from www.techkits.com because it generates about 1000 psi pressure.
You can remove the epoxy inserts and reuse the frame with a different epoxy mold.techkits.com
Using an epoxy mold is not for high volume production. The heat from the repeated injection of hot plastic can eventually soften the epoxy and you can lose details.If you allow the epoxy to cool between injections, you should be able to get a few dozen pieces.
The Model 150A injection machine works with any thermoplastic material up to 490 deg.F. So you can use common plastics like Polypropylene, Polyethylene, Polystyrene, ABS, etc.Tap plastics also sells color additives for the epoxy. I mixed in some black coloring to be able to better see the mold surface.
