Excellent Fluidity for Mold Filling: High fluidity ensures the liquid silicone fully penetrates every tiny gap of mold masters, capturing precise details and avoiding air bubbles, which is far superior to ordinary Condensation Curing Silicone Mold Rubber. 2. Stable Curing Performance: Advanced addition curing technology ensures uniform curing, no shrinkage, no toxic by-products, and consistent performance across batches, suitable for large-scale mold fabrication.
3. Safe & Versatile: FDA-certified, non-toxic, odorless, free of harmful substances, applicable to food-grade, craft and industrial mold fabrication, meeting global safety standards.
4. Easy Operation & Efficient: 1:1 weight ratio for simple mixing, dual curing options, no professional skills required, reducing labor costs and improving mold fabrication efficiency.
5. Durable & Cost-Effective: High tensile and tear strength supports 65~85 mold cycles, greatly reducing mold replacement costs and production waste.
6. Fully Customizable & Brand Assured: Hardness, color, operating and curing time can be tailored to fit diverse mold fabrication needs; as a national high-tech enterprise, we provide one-stop solutions and technical support.
How to Use (Step-by-Step)
1. Mix Part A and Part B of the silicone liquid for mold fabrication in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes in an irregular direction until uniform and bubble-free—critical for mold detail 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.
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
This Silicone Liquid for Mold Fabrication is widely used in diverse mold manufacturing scenarios, including craft molds (resin, clay), food-grade molds (fondant, chocolate), industrial molds (metal crafts, alloy auto parts), precision handboard molds, epoxy resin molds, and large-scale concrete molds. It brings tangible value: improving mold qualification rate by 40%+, reducing fabrication time and waste, adapting to small-batch customization and large-scale production, and helping manufacturers deliver high-quality molds to global clients.
