Pre-heating molds worth the time?

[Skidder419]

Thoughts on preheating molds? Other than dead summer it can be pretty cold here I was thinking of using a toaster oven next to my microwave to help keep the molds around 100 degrees or so pre-pour. My garage is somewhat heated but with the door open and fans going it will have a hard time getting to 60 out there.

It depends on how many molds you are shooting at a time. When I shoot during the winter I use 6 molds so after the first 2 rounds, my molds stay warm enough I don't usually have a problem. If you are doing open pour, it may be beneficial to keep them heated as open molds cool faster than injection molds.

In the winter sometimes the room I'm working in is in the 30s.  I now use a hot plate to preheat the molds and injectors.  It has reduced many of the problems I was having.

I don’t see why that wouldn’t work.  I use a hot plate with a cast iron griddle on top of it. I also take a Qtip and oil those hard to shoot appendages which helps on the first few baits.

I have one of the pancake grill  it is about 12"x 16" i use it to heat injectors, set pyrex cups on, heat jig heads to paint, heat blending block, and if u want to heat molds it will do that, I don't heat molds as it takes too long for it to cool before u can open the mold but maybe u can just knock the chill off for like a min or so.Cub48
