Fabricating plastic parts?

william | Fabricating plastic parts? I guess this is sort of off-topic, but I don't know where else to ask...I need to replace a small plastic part on a mixer. It's a "tray" that the fader sits in, keeps the fader isolated electrically from the board and stabilizes it physically. It isn't available from the manufacturer. I got the bright idea to make one up, so I made a slightly oversized Play-Doh mold, greased it up with silicone spray, and filled it with epoxy. It made a perfect replica of the part, but it shrunk about 30%, so no go. I could buy some plastic and glue it up, but I'm not sure which plastic I need (nylon, polyester, polypropylene, etc) or what glue to use? Or should I try the mold again, using something different? Thanks for the help... |
