6. Fully Customizable: Hardness, color, operating and curing time can be tailored to fit diverse mold forming needs; we provide one-stop solutions as a national high-tech enterprise.
How to Use (Step-by-Step)
1. Mix Part A and Part B of the liquid silicone for mold forming in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes in an irregular direction until uniform and bubble-free—critical for precise mold forming and curing stability.
2. Vacuum degas the mixed silicone for 2~5 minutes; adjust time according to viscosity to eliminate bubbles that affect mold quality.
3. Pour the degassed silicone into the mold master, leveraging its excellent fluidity to fully fill all gaps and details for precise forming.
4. Cure at room temperature (4~5 hours) or heat at 80~120℃ for accelerated curing; cure for 24 hours before first use to extend mold life.
5. Gently demold the cured mold, clean thoroughly before reuse; store unused silicone sealed indoors, away from sunlight and rain to preserve its performance.
Application Scenarios
