Hongye Silicone Manufacturing Process of Pad Printing Silicone from Raw Material to Finished Product

Vacuum Mixing Precise formulas feed into vacuum mixing kettles under vacuum to avoid bubbles. Mixing time temperature vacuum degree strictly controlled. Each model from HY-901 to HY-916 has independent process parameters.

Degassing and Aging Deep degassing removes micro bubbles, precision filtration removes impurities. Filtered paste ages under constant temperature for stable internal structure. Aging time varies by model, critical for viscosity stability.

Packaging Automatic filling from 1kg to 200kg drums, each labeled with model batch date shelf life. Catalyst separately packed and tested. Clean environment, archive samples retained.

Finished Testing Viscosity hardness tensile tear elongation cure time all tested. COA report each batch. Monthly output over 100 tons, multiple automated lines, ISO 9001, exported to 138 countries.
