champ198 Posted August 30, 2022 Report Share Posted August 30, 2022 So tried my hand at making a silicone mold of a 5" swimbait. Used some mold making silicone i got from amazon. The mold on the outside cured fine but where the baits were at it was still all in a gel type stage and did not get hard like the rest of the mold. So that was a fail. Do you all have luck with the amazon,Michaels type mold making kits? I know I have seen some mold making kits through Lureworks for like $40. This is my first time with this stuff so im still trying to learn. Quote Link to comment Share on other sites More sharing options...
rhahn427 Posted August 30, 2022 Report Share Posted August 30, 2022 Sounds like it may not have been mixed enough Quote Link to comment Share on other sites More sharing options...

Depending on the brand of plastisol, that stuff will separate. Quote Link to comment Share on other sites More sharing options...
Fishermanbt Posted August 30, 2022 Report Share Posted August 30, 2022 If you used a soft plastic bait(s) as the master that is where you probably ran into trouble. Certain forms of silicone mold don’t play nice with soft plastics. I encountered this same issue while using a platinum cured silicone. Allowed it to set up for 8+ hours only to find the area around the bait I was copying was still gel like. Look at the description for cast-a-mold platinum silicone at specialtyresin.com. It gives some examples of materials the silicon is not compatible with. Don’t give up. There are workarounds to get the mold you want.
