5. Easy Operation & Customization: 1:1 weight ratio for simple mixing, dual curing options; softness, operating time, and curing time can be tailored to specific soft mold requirements.
6. Durable & Cost-Effective: High tensile strength and elongation at break, supporting 70~90 mold cycles, reducing product loss and replacement costs by 35% for purchasers.
How to Use (Step-by-Step for Soft Silicone Mold Making)
1. Mix Part A and Part B of Soft Silicone Rubber Molds in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes in an irregular direction until uniform and bubble-free—critical for soft mold quality.
2. Perform vacuum degassing for 2~5 minutes; adjust time based on silicone viscosity, weight, and vacuum intensity to eliminate bubbles affecting detail replication.
3. Pour the degassed silicone into the mold master, leveraging its good fluidity to fill all intricate details.
4. Cure at room temperature (25℃) for 4~5 hours, or 80~120℃ for accelerated curing to retain ultra-soft performance.
5. Store unused silicone in sealed packaging, indoor storage away from sunlight and rain, and use within 10 months to maintain its soft and flexible properties.
