6. Easy Operation & Customization: 1:1 mix ratio, dual curing options; hardness and curing time can be tailored to precision mold needs, with brand standardized production guarantee.
How to Use (Step-by-Step)
1. Mix Part A and Part B of the durable silicone in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes until uniform and bubble-free (critical for precision and durability).
2. Vacuum degas the mixture for 2~5 minutes (time varies by viscosity) to eliminate bubbles affecting mold precision and service life.
3. Slowly pour the degassed silicone into the master mold, leveraging its excellent fluidity to ensure full coverage of all intricate details.
4. Cure at room temperature (4~5 hours) or heat at 80~120℃ for accelerated curing, fitting precision mold production timelines.
5. Gently demold the cured silicone mold, clean and store properly after use; unused silicone should be sealed indoors, away from sunlight and rain to preserve its durability.
Application Scenarios
This durable silicone for precision mold making is widely used in high-demand precision scenarios, including rapid prototyping silicone molds, industrial Mold Silicone rubber production, high-precision handboards, metal craft molds, resin casting molds, and Food grade mold silicone production. It brings tangible value: extending mold service life by 50%+, reducing replacement costs, ensuring consistent precision across batches, and helping mold manufacturers meet the rigorous demands of the global precision mold market.
