Title: plastic for a bait mold
Post by: link22eragon on 02/08/15 15:51 UTC

So i was just wondering. people make their own molds out of silicone alot, but if you were to make a two piece injection mold i thought it would be easier to use plastic instead. it would probably hold up better without the bend like silicone. does anyone know if this would work? i dont want to waste my money buying liquid plastic if it wont. i already have a plan on how to do it so i just want to know if the plastic would work.

I wouldn't use plastic.  I would use RTV it will hold up longer.

Plastic may not hold up to the heat very well for one thing.  For another, not all plastics are compatible with plastisol baits.  I think we've all experienced putting baits on a piece of plastic and having it melt from a reaction between the 2 plastics.

Make sure what ever plastic you use, uses the same resin that is in your baits.  If not, just like what was said above, it will get eaten through.

Plaster of Paris or Durham's water putty can be used for two piece molds. Just put a marble in each corner of the first half, paint the surface with vaseline and then pour the second half on.
