HONG YE SILICONE Jewelry Molding Silicone Rubber is a professional High transparency mold silicone designed for precision jewelry mold making. As premium Mold Making Silicone and liquid silicone, it features excellent tear and tensile strength, supporting both room-temperature and heating curing. With ultra-low shrinkage, easy demolding and no mucus residue, it ensures jewelry surfaces remain glossy and transparent, ideal for replicating rings, gem imitations, resin drills and various wearable accessories. It helps global jewelry manufacturers improve mold durability, enhance product gloss and reduce production costs.
Product Overview
This specialized silicone rubber is engineered for the rigorous demands of jewelry molding, focusing on high transparency and precision to replicate fine details of jewelry and gemstones. We offer two types: room temperature vulcanization (RTV 2 Silicone Rubber) models HY-E635, HY-E640, and heating temperature vulcanization models HY-MJ2135, HY-MJ2140. As a two-component liquid silicone, it combines flexibility and durability, ensuring molds are not easy to tear or crack, while delivering superior gloss and refractive index for finished jewelry, making it a top choice for jewelry mold manufacturers worldwide.

Product Features & Advantages
High transparency ensures clear mold visibility, capturing every fine detail of jewelry and gemstones. Excellent tear and tensile strength makes molds durable, with edges not easy to tear or crack. Dual curing options (room temperature/heating) adapt to different production rhythms. Superior high temperature resistance maintains mold stability during heating curing. Finished jewelry boasts good gloss and high refractive index, retaining transparency and luster. Ultra-low shrinkage guarantees precise jewelry size and shape consistency. Easy demolding with no mucus residue, no damage to delicate jewelry surfaces. Compared to competitors, our silicone offers better gloss retention and mold durability.
How to Use the Product
Step 2: Select the appropriate model (room temperature/heating), mix Part A and Part B at the recommended ratio, stir evenly for 2-3 minutes.
Step 3: Perform vacuum defoaming for 1-2 minutes to eliminate air bubbles (critical for transparency).
Step 4: Pour the mixed silicone into the jewelry prototype mold, fully covering all details.
Step 5: Cure at 25℃ (4-6 hours) or heat (accelerate curing), demold gently after full curing.
Step 6: Inspect the mold and test-cast jewelry to ensure gloss and precision.
Application Scenarios
Widely used for mold making of jewelry, diamonds, resin drills, acrylic drills, PVC accessories, imitation gems, water drills, and wearable accessories like rings, necklaces, and earrings. Suitable for mass reproduction of flat bottom drills, three-dimensional resin drills, imitation agate, amber, jadeite, and imitation Swarovski drills. Ideal for jewelry factories, resin drill manufacturers, and custom jewelry workshops. It helps buyers improve product gloss and qualification rate, extend mold service life, and reduce defective rates and production costs.
Certifications and Compliance
Complies with ISO 9001 quality management system and CE industrial standards. Non-toxic, odorless, and meets international safety requirements for jewelry production. All formulas conform to international chemical transportation and import regulations, supporting smooth cross-border B2B bulk procurement.
Customization Options
Supports hardness customization (30-45 Shore A) to adapt to different jewelry sizes and details. Provides transparency adjustment for specific gloss requirements. Optimizes curing speed to match production efficiency. Offers formula modification for enhanced tear strength or temperature resistance. Customizes packaging from small test jars to industrial bulk drums according to order volume.
Production Process
Adopts high-purity Silicone raw materials, undergoes precise proportioning, closed-loop vacuum mixing (to maintain transparency and avoid bubbles), multi-index testing (transparency, tear strength, shrinkage rate), automatic filling and sealed packaging. Each batch undergoes strict quality inspection to ensure consistent performance, with mature production lines guaranteeing on-time delivery for small-batch tests and large-scale bulk orders.
FAQ
Q1: Will the silicone affect jewelry gloss?
A1: No, it has no mucus residue and ensures finished jewelry retains high gloss and transparency.
Q2: Can it replicate tiny details of gem imitations?
A2: Yes, high transparency and fluidity capture every fine detail of gemstones and jewelry.
Q3: What’s the difference between room temperature and heating curing models?
A3: Room temperature models are convenient for small batches; heating models speed up curing for mass production.
Q4: How many times can a mold be reused?
A4: 80-120 times with proper maintenance, thanks to high tear strength.
Q5: Is it suitable for imitation Swarovski drill molds?
A5: Yes, it perfectly replicates the gloss and refractive index of imitation Swarovski drills.
