HONG YE SILICONE Silicone for Car Parts Molding is a high-performance two-component Addition Curing Silicone, also known as Industrial mold silicone rubber and Mold Making Silicone. This liquid silicone features ultra-low linear shrinkage (≤0.1%), deep curing ability, and excellent high and low temperature resistance (-50~250℃). Non-toxic, odorless, and with good fluidity, it is specially engineered for automobile parts molding, ideal for car tires, hoods, steering wheels, and precision auto components. It helps global B2B auto parts manufacturers improve mold precision, extend mold service life, and reduce production costs.
Product Overview
This specialized silicone rubber is tailor-made for the rigorous demands of car parts molding, crafted as a high-elasticity polymer two-component liquid silicone (Part A: base silicone, Part B: curing agent) with excellent fluidity. It supports deep vulcanization, pouring, and coating, with simple and convenient operation that requires no professional skills. Its ultra-low shrinkage ensures stable volume during crosslinking, guaranteeing precise replication of car parts details. Suitable for both large auto components (hoods, shells, tires) and small precision parts (rear-view mirrors, interior crafts), it is a reliable solution for auto parts mold making.

Product Features & Advantages
Ultra-low linear shrinkage (≤0.1%) ensures no volume change during crosslinking, guaranteeing high dimensional precision of car parts molds. Deep curing ability, not limited by mold thickness, suitable for both thick and thin auto component molds. Non-toxic and odorless, ensuring safe operation in production workshops. Excellent fluidity enables easy pouring and coating, fully filling complex car part details. Superior chemical corrosion resistance and temperature resistance (-50~250℃) adapt to harsh production environments. High tensile and tear strength extends mold service life, supporting multiple repeated molding cycles. Simple operation reduces training costs, improving production efficiency compared to competitors.
How to Use the Product
Step 2: Mix Part A and Part B at 1:1 weight ratio, stir evenly for 2-3 minutes to ensure full integration.
Step 3: Perform vacuum defoaming for 1-2 minutes to eliminate air bubbles, ensuring smooth mold surfaces.
Step 4: Pour or coat the mixed silicone onto the car part prototype, fully covering all details.
Step 5: Cure at room temperature (25℃) for 4-6 hours, or heat to accelerate curing; demold gently after full curing.
Step 6: Inspect the mold for precision before formal mass production.
Application Scenarios
Widely used for mold making of automobile parts, including car tires, hoods, engine hoods, car shells, doors, rear-view mirrors, steering wheels, auto interior crafts, and precision auto components. Also suitable for yacht gel coat, alloy car models, and high-quality mold casting crafts. Ideal for auto parts manufacturers, auto mold factories, and custom auto component suppliers. It helps buyers improve car parts mold precision, reduce defective rates, extend mold service life by 50%+, and lower production and replacement costs.
Certifications and Compliance
Complies with ISO 9001 quality management system and CE industrial standards. Non-toxic and odorless, meeting international industrial safety requirements for auto parts production. All formulas conform to international chemical transportation and import regulations, supporting smooth cross-border B2B bulk procurement.
Customization Options
Supports customization of hardness (20-40 Shore A) to adapt to different car part textures and weights. Provides fluidity adjustment for complex or large auto component molds. Optimizes curing speed to match production rhythms. Offers formula modification for enhanced chemical corrosion resistance 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 and premium additives, undergoing precise 1:1 proportioning, closed-loop vacuum mixing (to maintain fluidity and avoid bubbles), multi-index testing (shrinkage rate, temperature resistance, tensile strength), automatic filling and sealed packaging. Each batch undergoes strict quality inspection to ensure stable performance, with mature production lines guaranteeing on-time delivery for small-batch tests and large-scale bulk orders.
