tigerfire Posted May 7, 2013 Report Share Posted May 7, 2013 Can you pour hot plastic into a wooden mold and get a bait out? I have a wood cavity that I wanted to pour plastic into, but I didn't know if the plastic would stick to the wood or if the wood would be able to handle the heat of the plastic? I'm not a wood guy, so I don't know what kind of wood. I just need to get one or two pours out of it. Quote Link to comment Share on other sites More sharing options...

Travis Posted May 7, 2013 Report Share Posted May 7, 2013 You should be fine for a few pours. Are you able to saturate the wood with PAM, WD40, etc... prior. You can also just cut some Devcon 5 minute epoxy and do multiple coats and seal it before use. Quote Link to comment Share on other sites More sharing options...
RayburnGuy Posted May 7, 2013 Report Share Posted May 7, 2013 I don't pour plastic nor do I build a lot of molds, but couldn't you just seal the wood with a thinned epoxy? Lot of folks use epoxy to seal wooden cranks against water intrusion and if the epoxy is applied properly the plastic would never touch the wood. Epoxy also leaves a really slick surface if you make sure to get tiny the bubbles out of it. Ben Quote Link to comment Share on other sites More sharing options...
tigerfire Posted May 8, 2013 Author Report Share Posted May 8, 2013 Good ideas. I need to keep the wood untouched so I can't coat it with anything. Maybe the Pam or WD40 but I need to see if they contain water. I'm more concerned about damaging the wood. Quote Link to comment Share on other sites More sharing options...
alsworms Posted May 8, 2013 Report Share Posted May 8, 2013 Maybe Jeff at MF could chime in here, but I believe some of their first molds were made of wood?? If so, not sure what they used (if anything) to coat them with. Quote Link to comment Share on other sites More sharing options...
tigerfire Posted May 10, 2013 Author Report Share Posted May 10, 2013 Got around to pouring into the wood last night. No problems at all. I didn't coat the wood with anything, just poured plastic straight into the cavity. I waited for the plastic to cool to 300 degrees on the first couple of pours, but after that I was pouring at 330 degrees. I'm sure I could have poured it even hotter if needed. I didn't see any problems with the wood after the pouring. Quote Link to comment Share on other sites More sharing options...
yoda Posted May 10, 2013 Report Share Posted May 10, 2013 I asked about this a few years ago when Sears came out with a small wood cnc machine but i was thinking about making a block of bondo resin and using that in place of wood would like to hear if anyone has one and if it's possible.

longhorn Posted May 15, 2013 Report Share Posted May 15, 2013 If you coat the cavities with Elmer's Glue it will have the finish and release similar to a POP mold. Quote Link to comment Share on other sites More sharing options...
rhahn427 Posted May 15, 2013 Report Share Posted May 15, 2013 Glad it worked for you. I would only pour 1 or 2 and ues them to make a mold for the lure if you are concerned about the wood because you will probably get some of the oils in the pores of the wood if you continue.
