1.Solid silica gel molding process: solid silica gel products are usually through the high temperature mold into the addition of (double 25 or double 24) silicone vulcanization agent compound, and then through the plate vulcanization machine pressure, high temperature sulfur into solid molding, the hardness of molded silica gel is usually in (Shore hardness)30-70A. In the process of producing rubber mixing in silica gel factory, the raw rubber is first added to the two-roll rubber mixing machine or the closed kneading machine and gradually adds white carbon black, silicone oil and other additives to the repeated refining. According to the different fillers and additives, the performance of silica gel is also different.

2. Silicone extrusion molding process: silicone extrusion products are usually extruded by extrusion machine silicone molding, is a continuous molding process, can be suitable for double 24 sulfide solid silicone or platinum vulcanization agent catalytic liquid silicone production and processing. It is a process in which silicone rubber is continuously made into semi-finished products of different shapes under the interaction of the cylinder of the silicone extruder and the rotating screw. It can be used to process silicone tubes, silicone wire and cable insulation sleeves and other silicone products.
