HONGYE SILICONE’s liquid silicone for mold making is a professional two-component Addition Curing Silicone, designed exclusively for high-quality mold manufacturing. As a national high-tech enterprise with standardized production and one-stop solutions, this Mold Making Silicone features excellent fluidity, deep curing performance, and extreme temperature resistance (-60℃~250℃). It is FDA-certified (food-grade optional), highly tensile and tear-resistant, and fully customizable, helping global mold manufacturers reduce production costs, improve efficiency, and create durable molds for diverse industries.
Product Overview
Our liquid silicone for mold making is a premium RTV 2 Silicone Rubber, composed of flowable Part A and Part B, ideal for all types of mold production. This Liquid Mold Silicone is easy to operate, supporting both room-temperature and heat curing, making it suitable for mass production, custom mold creation, and rapid prototyping. Unlike ordinary silicone, it achieves deep curing without being limited by mold thickness, ensuring uniform hardness and stable performance. Widely used in food-grade mold, metal crafts, cement components, cultural stone, and precision handboard mold manufacturing, it also integrates with Rapid prototyping silicone applications, providing a versatile solution for global buyers.

Product Features & Advantages
1. Superior Deep Curing: No limitation by mold thickness, ensuring uniform curing for both small delicate molds and large-sized industrial molds, avoiding uneven hardness or deformation.
2. Dual-Grade Adaptability: Optional Food grade mold silicone (FDA-certified, non-toxic, odorless) for food-related molds, and industrial-grade for heavy-duty applications like cement components. 3. Excellent Thermal Stability: Withstands extreme high and low temperatures without brittleness or performance degradation, adapting to diverse production environments.
4. Easy Operation: Superior fluidity for easy pouring and filling of tiny mold details; 1:1 mix ratio and dual curing options simplify production, reducing operational difficulty.
5. High Durability: High tensile and tear resistance, supporting 50~90 mold turns, reducing mold replacement costs and improving production efficiency.
6. Full Customization: Color, operating/curing time, and hardness are customizable, matching different mold types and production needs, distinguishing us from competitors with fixed specifications.
How to Use (Step-by-Step)
1. Component Mixing: Combine Part A and Part B in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes until the mixture is uniform and free of streaks or air bubbles.
2. Vacuum Degassing: Place the mixed silicone in a vacuum chamber for 2~5 minutes to remove air bubbles; adjust the time according to silicone viscosity, weight, and vacuum strength to avoid mold defects.
3. Pouring & Filling: Slowly pour the degassed silicone into the master mold, ensuring full coverage of all details and contours.
4. Curing: Cure at room temperature (4~5 hours) or heat at 80~120℃ for accelerated curing (tens of minutes) until fully set and elastic.
5. Demold & Storage: Gently demold the silicone mold for use; store unused silicone in a sealed container indoors, away from sunlight and rain.
Application Scenarios
Our liquid silicone for mold making is widely applied in multiple industries: food-grade molds (pastry, ice cream, chocolate), metal crafts, alloy auto parts, epoxy resin/polyester resin crafts, large cement components, cultural stone, concrete molds, and precision handboard model making. It also supports Rapid prototyping silicone for quick mold design iterations. For mold manufacturers, food processing enterprises, and industrial product factories, our silicone reduces production costs, improves mold precision and durability, enhances product competitiveness, and meets diverse global market demands.
