Silicone rubber products are the activities of producing various silicone rubber products with silicone and rubber as the main raw materials. Used in new energy vehicles, household appliances, aerospace, rail transit, electronic communications, medical equipment and other industries.
1. Solid silicone molding process:
Solid silicone products are usually through the high temperature mold into the addition of (double 25 or double 24) silicone vulcanization agent of the compound, and then through the plate vulcanization machine pressure, high temperature sulfur into solid molding, molded silicone hardness 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 process:
Extruded silica gel products are usually extruded silica gel molding by extrusion machine, which is a continuous molding process, which can be suitable for double tetrasulfide solid silica gel or platinum vulcanization agent catalytic liquid silica gel 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.
3. Liquid silicone molding process:
Liquid silica gel English abbreviation LSR, is a kind of products that can be favored by consumers and manufacturers, has good elasticity and waterproof and moisture resistance, acid, alkali and other chemical substances erosion, so it is generally used to replace living plastic products. Liquid silicone products are molded by silicone injection molding, injection, injection; LSR is divided into A glue and B glue, the ratio of the two is 1:1 controlled by the quantification device, and then the static mixer is fully mixed, injected into the injection pipe and then the injection molding production.
4. Other silicone molding process:
Other (special silicone molding process) Special silicone products are based on the chemical properties of silicone or the addition of some auxiliary raw materials, special silicone products can also have high temperature resistance (up to 330 degrees), food grade (fully in line with the US FDA,LFGB standard), medical grade, flame retardant grade, by adding auxiliary raw materials can also have, luminous, negative ions, discoloration, Such characteristics. This kind of product bonding needs the characteristic requirements of silicone glue to meet.
