Product Description

HONGYE SILICONE’s High pure silicone for mold casting use is a premium dual-component Addition Curing Silicone, tailored for global B2B purchasers in mold casting, precision molding, high-end craft casting, and industrial mold manufacturing. As a national high-tech enterprise with standardized production and one-stop solutions, this high-pure silicone features ultra-high purity, excellent fluidity, FDA food-grade safety, and full customization. It supports room/heat curing, flawless mold replication, and long-term reuse, helping purchasers improve casting quality, reduce rejection rates, and gain competitive advantages in mold casting markets.

Product Overview

Our High pure silicone for mold casting use is a professional high-purity solution engineered for mold casting, composed of ultra-pure organic silicon raw materials (Part A: base rubber; Part B: curing agent) via advanced addition curing technology and strict multi-stage purification processes. It solves the pain point of ordinary Mold Silicone with impurities, poor casting precision, and unstable performance, which affects mold quality and service life. Unlike standard mold silicone, our high-pure silicone is free of harmful residues, cures into a uniform, durable elastic body, non-toxic odorless, with ultra-low shrinkage and excellent fluidity, ideal for various mold casting scenarios, fully complying with global quality and safety standards.

Product Images and Videos

High-quality visuals include close-ups of the high-pure silicone’s clean, uniform texture, purification process snippets, mixing and pouring processes, finished molds and casting results, with original image links retained. Demonstration videos cover the full mold casting workflow—1:1 mixing, vacuum degassing, mold pouring, curing, and demolding—highlighting easy operation, ultra-high purity, and flawless mold replication for casting use.

Step-by-Step Usage Guide

1. Prepare a clean, dust-free, contaminant-free environment to maintain the silicone’s high purity and ensure mold casting quality.

2. Mix Part A and Part B at a 1:1 weight ratio, stirring thoroughly for 2~3 minutes until fully blended and bubble-free (critical for purity and casting precision).

3. Perform vacuum degassing for 2~5 minutes (adjust based on viscosity/weight) to remove trapped air, avoiding mold defects.

4. Pour the degassed high-pure silicone slowly into molds, ensuring full coverage of all fine details and complex structures.

5. Cure at 25℃ for 4~5 hours, or accelerate at 80~120℃ for faster turnaround; post-cure enhances durability and purity stability.

6. Store unused silicone in sealed containers indoors, avoid sunlight/rain, use within 10 months; keep away from N/P/S compounds to prevent curing failure.

Application Scenarios & Customer Value

Widely used in mold casting, including high-simulation food molds, metal craft casting, alloy automotive part molds, epoxy/polyester resin casting, precision handboard prototyping, and large cement component molds. It improves mold casting qualification rate by 65%+, reduces mold damage by 60%, and ensures consistent casting quality, helping businesses optimize production efficiency, lower long-term costs, and gain trust in global mold casting markets.
