Is there anything I can do to prolong the life of the mold?Updated 23 days ago
Using mold release before pouring parts can double the life of your mold. Over time, the silicone oil will absorb into the silicone rubber mold to replenish some of the oil that has been lost during normal casting and demolding of your parts. The other option is to use a bake out process. A bake out process of the silicone rubber will help remove hardeners, plasticizers, and other materials that leach out of the casting resin materials that are on the molds surface. A slow gradual bake of 200 degrees F for 8 hours or 400 degrees F for 2 hours is recommended. This will also draw silicone oil within the rubber mold back to the surface to replenish what has been depleted. It is recommended to do this throughout the entire life of the mold rather than only when the mold dries out and is near the end of its life.
