HONGYE SILICONE’s Smooth Casting Silicone Molds is a premium two-component addition curing
liquid silicone, specialized for producing ultra-smooth, high-gloss mold surfaces. As a national high-tech enterprise with standardized production and one-stop solutions, this silicone is FDA-certified, non-toxic, odorless, featuring excellent fluidity, smooth curing, and easy demolding. It caters to global B2B purchasers’ demand for smooth casting molds, ensuring flawless surface replication, consistent quality, and flexible customization, helping improve product finish, reduce post-processing costs, and enhance competitiveness in high-end casting markets.
Product Overview
Our Smooth Casting Silicone Molds is a high-gloss
RTV 2 Silicone Rubber, composed of high-purity flowable Part A (base rubber) and Part B (curing agent), adopting advanced addition curing technology. Focused on smooth casting effects, it supports both room-temperature and heat curing with simple operation, achieving shrink-free deep curing without thickness limits and producing no toxic by-products. Unlike ordinary
Mold Making Silicone with rough surfaces, it solves the pain points of uneven mold surfaces, poor gloss, and difficult post-processing, making it the preferred choice for global B2B purchasers in high-end casting mold manufacturing.

3. Safe & Odorless: FDA-certified, non-toxic, odorless, suitable for food grade
Mold Silicone and high-end casting scenarios requiring safety and cleanliness.
4. Excellent Fluidity: Superior fluidity enables full filling of mold details and uniform surface formation, ensuring consistent smoothness across batches.
5. Easy Operation & Customization: 1:1 weight ratio for simple mixing, dual curing options; hardness, surface gloss, and curing time can be tailored to specific smooth casting needs.
6. Durable & Cost-Effective: High tensile and tear strength, supporting 80~100 mold cycles, reducing post-processing costs by 40% and improving production efficiency.
How to Use (Step-by-Step for Smooth Casting)
1. Mix Part A and Part B of Smooth Casting Silicone Molds in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes in an irregular direction until uniform and bubble-free—critical for smooth surface formation.
2. Perform vacuum degassing for 2~5 minutes; adjust time based on viscosity, weight, and vacuum intensity to eliminate bubbles that affect surface smoothness.
3. Pour the degassed silicone into the mold master slowly, leveraging its good fluidity to form a smooth surface without air bubbles.
4. Cure at room temperature (25℃) for 4~5 hours, or 80~120℃ for accelerated curing to retain ultra-smooth performance.
5. Store unused silicone in sealed packaging, indoor storage away from sunlight and rain, and use within 10 months to maintain its smooth casting properties.
Application Scenarios
