Keeping Molds Warm

[J lure]

I noticed there has been alot of posts where guys are having problems with denting and molds not filling correctly. I was wondering who warms thier molds before injecting or how do you guys keep your molds warm during the injecting process? I was thinking about a heating pad or some type of hot plate or flat griddle.... Any thoughts

Presto Griddle K-Mart is where I got mine about $25

i dont heat any molds, and in fact i try to keep them cool rather than warm.

Denting happens when the supply of hot plastic solidifies before the bait cools. then as the bait cools and shrinks and doesn't have anywhere to draw fresh plastic from and dents. most of the times it is the gate area in an injection molds that does this.

after they have been filled a few times w/ hot plastic they are too warm for me,

this would be for hand pouring.

In the winter, I heated mine on the dash of my truck. Turn it on defrost with the heat on high, and start to heat some plastic in the microwave.

By the time the plastic is ready so are the molds and injector

The plastic is hot enough to to keep the molds warm once injecting has started.

Spring, summer and early fall I don't warm my molds. No need

I wonder if you could convert the radiator into an injector

_{Some molds I like warm use an electric hot plate, just to get them started. Checking the plastic temp helps. I have one mold I shoot cold as the plastic stays hot too long and will cause sink marks when I pull out the craw.}
