3. Dimensional Stability: Low shrinkage performance remains stable under long-term use, high temperature or vibration, no dimensional drift, ensuring consistent quality of batch-produced precision products.

4. Precision Compatibility: Compatible with HONG YE SILICONE’s high-precision mold silicone and rapid prototyping silicone, forming a complete high-precision molding solution, enabling one-stop procurement for precision product buyers.

5. Easy Precision Operation: 1:1 simple mixing ratio, good flowability, easy to fill high-precision mold gaps, no professional precision operation skills required, improving production efficiency and reducing precision defects.

 

 

1. Take Part A and Part B according to 1:1 weight ratio, stir separately to eliminate sediment, ensure no impurities (avoid affecting molding precision).

2. Mix and stir thoroughly for 2-3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure pore uniformity and molding precision).

3. Pour the mixture into high-precision mold (paired with high-precision mold silicone), foam and cure at room temperature or by heating.

4. After full curing, demold gently, the product has high dimensional precision, no deformation, ready for direct use without secondary trimming.

 

Focus on high-precision scenarios: High-precision electronic component molding (paired with Electronic Potting Compound), precision medical auxiliary parts (paired with Medical Grade Body Silicone), precision robot components (paired with robot silicone), rapid prototyping of precision parts (paired with rapid prototyping silicone), and high-precision mold filling (paired with high-precision mold silicone). It helps precision product buyers improve product dimensional accuracy and market competitiveness.

 

Passed SGS eco-toxicity certification, RoHS compliant, ultra-low shrinkage rate, meeting the high-precision procurement requirements of B2B buyers in various industries, facilitating export to global high-precision product markets.

 

 

Customizable shrinkage rate (≤0.05% for high-demand scenarios), pore size (30-150μm), viscosity and curing time, adapting to different high-precision molding requirements, ensuring customized products maintain high dimensional stability.

 

Low-shrinkage-oriented production process: High-purity low-shrinkage Silicone raw materials → formula optimization (reduce curing shrinkage) → precision mixing → shrinkage rate test → standardized curing → dimensional precision inspection → packaging. Strict shrinkage control ensures high molding precision of each batch.
