I pour musky fishing baits using AlumiFoam and need a mold that can handle the abuse. Currently using HS2 and lucky to get 15 baits poured using that mold. I will sit for a day and just pour the AlumiFoam. I am at a point that I need to make multiple molds to keep up with demand and want a mold to last longer. Thanks for any help.
Are you warming the molds before pouring and/or using silicone oil in them after finishing your pouring for the day? Both of those will help but you really should be getting more than 15 pours per mold. I normally use HS-3 and get more than enough pours out of each mold but HS-2 and HS-3 should both get almost the same number of pours per mold. It's a little odd that you're getting so few.
