There is no glow mold or cfr mold
Layered thermosets such as polyurethane has to cured/vulcanized at specific temperatures resulting in polymers which need specific molds to be injected to otherwise it does not set correctly. There are many different machines used, with interchangeable injection base mold templates sets based on the temperature of the injection some self cure some do not. This is what results in the plh everyone complains about when new/alternative mixtures in introduced or not available in supply when they receive stock from their supplier, or the supply costs way to much because most of the chemical and baseline stocks have been off shored since the mid 90's or the plant that makes a certain type is no longer in business from off shoring.
When a disc cools is another story.
What do I know, I'm just an chemical engineer.
