Blackmarketbaits Posted April 23, 2020 Report Share Posted April 23, 2020 Hey all, I hope everyone is keeping sane with the ongoing current events! So I just poured a fairly large mold, 8x8 sq in. roughly. its a injection mold for 5 in. paddletail swimbaits. and I was a little short on the aluminum powder resin to fill above the highest point of the masters. i completely covered the surface of the parts though. I have some Expanding foam resin, the tough stuff, laying around. could i just pour that in to make a backing for the mold halves? the foam and the aluminum powder resin are all urethane based so they would bond together right? or am a wrong in thinking that? i have multiple walleye anglers chomping at the bit to buy these after seeing the results in field testing last spring. if I have to I will wait until i get more of the Aluminum resin. thats alot of money in molds and time in the masters.

Anglinarcher Posted April 24, 2020 Report Share Posted April 24, 2020 I second what Larry told you, with one minor addition. If you keep the master in the original mold so the Alumifoam can't expand and deform the cavity, it will work. The only problem will be what to do with the overexpansion. That stuff is tough. I made some floating jigs from Alumifoam and poured some bodies only so a friend could cut his own slits and glue in his own hooks. It didn't work so well for him, the Alumifoam is so tough it was almost impossible to cut. LOL Figure out how to remove the excess foam before it fully cures if you go that route. 1 Quote Link to comment Share on other sites More sharing options...
