Frequently Asked Questions
Can we Prototype Silicone Rubber?
Yes and No. If you build a plaster or silicone mold, you can hand inject RTV (room temperature vulcanization Silicone). It is more difficult to inject LSR (liquid silicone rubber) into anything but a metal mold because you need to elevate the temperature of the mold to get the LSR to cure.
Casco Bay Molding builds tool steel Short Run – Prototype Silicone Rubber core and cavity sets for customers who want to have LSR Silicone parts
Can we try different Durometers?
Yes. Once the core & cavity set or mold is completed Casco Bay Molding can run various Durometers in the same mold. Liquid Silicone Rubber is delivered in a closed “sheet rock bucket” or 55 gallon drum sets. Each Durometer has its A & B sides that is pumped into the injection molding machine.
