Material Preparation
Base Material Addition-Cure Liquid Silicone: Features include no release of low molecular substances during vulcanization, low shrinkage rate (typically less than 0.1%), high temperature resistance, high tear strength, and good fluidity, making it suitable for detailed model replication.
Curing Agent: Special curing agent for addition-cure silicone, which must be mixed with the silicone in a specific ratio (commonly 1:1 or 10:1; refer to product instructions for details).
Plaster Powder: Choose high-strength, fine plaster powder (such as medical plaster or mold-specific plaster) to ensure mold strength and surface smoothness.
Release Agent: Such as Vaseline, liquid paraffin, or specialized silicone release agent to prevent adhesion between silicone and the prototype or plaster.

Mixing Addition-Cure Liquid Silicone
Weighing Materials: Based on the prototype volume, weigh the addition-cure liquid silicone and curing agent in the specified ratio (e.g., 1:1 ratio requires equal amounts of silicone and curing agent). Ensure accurate measurements, as imbalanced ratios may lead to incomplete curing or reduced performance.
Thorough Mixing: Pour the curing agent into the silicone and stir slowly in one direction using a mixing rod to avoid excessive bubbles. Mix for approximately 3-5 minutes until the mixture is uniform in color.
Debubbling (Optional): For higher precision molds, place the mixed silicone into a vacuum machine for 5-10 minutes to remove bubbles completely. If a vacuum machine is unavailable, let the mixture sit for 10-15 minutes to allow bubbles to rise and dissipate naturally.
