Product Features & Advantages
1. Professional-Grade Performance: Strictly produced to industrial standards, with stable batch performance (error ≤2%), ensuring consistent mould quality for mass production, superior to ordinary Mold Silicone. 2. Shrink-Free Deep Curing: No thickness limits, ensuring moulds retain their shape and precision after curing, avoiding deformation and improving product qualification rates.
3. Food-Grade Safety: FDA and RoHS certified, non-toxic, odorless, no harmful by-products, suitable for food-contact mould manufacturing and high-standard industrial scenarios.
4. High Durability: High tensile and tear strength, supporting 100~120 mold cycles, 35% longer than ordinary mould silicone, reducing mould replacement costs and production losses.
5. Easy Operation & Customization: 1:1 mix ratio for simple operation; hardness, operating time, curing time, and color can be tailored to diverse professional mould requirements.
6. Excellent Fluidity: Easily fills all mould details, ensuring vivid, accurate replication of prototypes, suitable for high-precision mould manufacturing.
How to Use (Step-by-Step for Mould Making)
1. Mix Part A and Part B of the professional grade silicone in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes in an irregular direction until uniform and bubble-free.
2. Perform vacuum degassing for 2~5 minutes; adjust time based on viscosity, weight, and vacuum intensity to eliminate bubbles and avoid mould defects.
3. Pour the degassed silicone into mould masters, leveraging good fluidity to fill all tiny details and gaps.
4. Cure at room temperature (25℃) for 4~5 hours, or 80~120℃ for accelerated curing to meet tight production schedules.
5. Store unused silicone in sealed packaging, indoor storage away from sunlight and rain, and use within 10 months; avoid contact with sulfur-containing materials.
Application Scenarios
Our Professional Grade Silicone for Moulds is widely used in global professional mould manufacturing, including high-simulation food moulds, metal crafts, alloy car accessories, epoxy resin/polyester resin moulding, large cement components, cultural stone, concrete moulds, and precision handboard models. It brings tangible value: reducing mould replacement costs by 40%+, improving production efficiency by 25%, ensuring stable mould quality, and supporting mass production, helping B2B purchasers reduce costs and enhance competitiveness in the professional mould market.
