Product Features & Advantages
Ultra-Precision Replication: Captures even the finest mold details (e.g., texture patterns, micro-carvings) with 0.01mm accuracy, outperforming standard Mold Making Silicone in custom project fidelity. Advanced Addition Curing: No by-products during curing, ensuring zero shrinkage and stable mold dimensions—critical for high-precision custom applications, and more reliable than Condensation Curing Silicone Mold Rubber. Full Customization Flexibility: Tailor hardness, operating time, curing time, and color to match specific mold requirements (e.g., soft molds for food simulation, rigid molds for metal crafts).
Extreme Temperature Stability: Maintains performance from -60℃ to 250℃, suitable for molds used in high-heat casting or low-temperature storage environments, expanding application versatility.
High Durability & Cost Efficiency: High tensile/tear resistance supports 50~80 mold cycles, reducing replacement costs for bulk custom production; FDA-certified for food-contact applications.
User-Friendly Operation: 1:1 mix ratio, no specialized equipment required, and easy vacuum degassing for consistent quality in both small-batch and large-scale custom projects.
How to Use (Step-by-Step)
Mixing: Combine Part A and Part B at a 1:1 weight ratio, stirring thoroughly for 2~3 minutes until uniform and bubble-free (critical for precision).
Vacuum Degassing: Subject the mixture to 2~5 minutes of vacuum treatment (adjust time by viscosity) to eliminate bubbles that disrupt detail replication.
Precision Pouring: Slowly pour the degassed silicone into the custom master mold, ensuring full coverage of intricate features using its optimized fluidity.
Curing: Cure at room temperature (4~5 hours) for low-heat projects, or heat at 80~120℃ for accelerated production (customize timing per project needs).
Demolding & Storage: Gently remove the cured silicone mold; store unused silicone in a sealed, indoor container away from sunlight/rain to preserve precision performance.
Application Scenarios
This precision silicone is ideal for custom mold applications across industries:
Precision Handboards & Rapid Prototyping: Replicate intricate design details for product development.
Metal Craft & Alloy Automotive Molds: Capture fine textures in decorative metal parts.
High-End Simulated Food Molds: FDA-certified for safe replication of realistic food models.
Resin/Polyester Casting Molds: Ensure sharp details in resin or polyester-based custom products.
Cultural Stone & Concrete Molds: Produce detailed architectural elements with consistent replication.
Value Proposition: Reduces procurement costs by replacing single-purpose silicones, cuts rework rates by 30% via precision replication, and shortens custom project lead times with flexible curing options—helping suppliers stand out in the competitive custom mold market.
