Product Description

HONG YE SILICONE’s liquid silicone for necklace molds is a two-component addition-cure material, tailored for high-precision necklace mold manufacturing. It supports room/heat curing with easy operation, featuring FDA food-grade safety, -60°C to 250°C temperature resistance, and excellent fluidity for fine details. With shrinkage-free deep curing, high tear resistance and reusable performance, it offers customizable parameters. Certified by ISO9001, CE and UL, it integrates our core products like Liquid silicone rubber, Mold Silicone mold-making silicone rubber and addition-curing RTV silicone rubber, trusted by global jewelry manufacturers.

Product Overview

This specialized liquid silicone consists of flowable A/B components, a core offering of HONG YE SILICONE with 20+ years of silicone expertise. Engineered for necklace molds, it cures into a durable elastic body without deformation, unaffected by thickness. Its superior fluidity captures intricate necklace details (carvings, hollow patterns), suitable for resin, metal, and alloy necklace mold production. Adhering to standardized production, it matches the quality of our HTV silicone rubber and solid silicone rubber, serving small-batch customization and large-scale production with one-stop solutions.

Technical Specifications

Base Material: Addition-cure organic silicone rubber; Mix Ratio (A:B): 1:1 by weight; Operating Time (25°C): 30-40 minutes (customizable); Curing Time (25°C): 4-5 hours, 80-120°C: 30-60 minutes; Temperature Resistance: -60°C to 250°C; Tear Strength: ≥20 kN/m; Hardness: 10-25 Shore A (customizable); Shelf Life: 10 months (sealed, indoor storage, no sun/rain exposure).

Product Features & Advantages

1. High-Fidelity Detail Capture: Shrinkage-free deep curing and great fluidity replicate tiny carvings, hollow structures, and textures, ensuring necklace molds are true to prototypes.

2. Safe & Reliable: FDA-certified, non-toxic odorless, compliant with jewelry skin-contact standards.

3. Easy Operation: Dual curing methods fit craft studios and factories, simplifying production.

4. Durable & Cost-Saving: High tensile/tear resistance, 300+ reuse times, reducing mold replacement costs.

5. Stable Quality: Standardized production lines with pre-production sampling and pre-shipment inspection, backed by ISO9001.

How to Use

1. Clean and dry the necklace prototype/mold frame to remove dust and oil.

2. Mix A/B at 1:1 weight ratio, stir thoroughly for 2-3 minutes until uniform.

3. Vacuum defoam for 2-5 minutes (adjust by viscosity/weight).

4. Pour slowly to fill detail areas, avoiding bubbles.

5. Cure at room temperature (4-5 hours) or 80-120°C (30-60 minutes). 6. Demold gently and trim excess silicone for finished molds.

Production Process

1. High-purity raw material selection and strict quality testing.
