I been molding resin with an aluminum master using a silicone mold and it's working ok, but when pouring excess material into a polyethylene measuring cup the resin doesn't stick at all. My question is, how to make a mold out of the polyethylene plastic. I've seen small trays with shapes and designs being offered at various websites. My countless hours of searching the web has me thinking the only way to do it would be through and injection process?? Any help would be much appreciated!!
