Different silicone products will be produced by different processes according to the characteristics of the products. There are basically the following six processes in the silicone industry:

1. Compression molding: This production process is the most common. It is completed by the cooperation of the mold, and the shape of the mold determines the shape of the silicone product. Molded silicone products are usually made by putting the solid silicone raw material with vulcanizing agent into the high-temperature mold and applying pressure through the vulcanizing machine. The high-temperature sulfur is solidified and formed. The hardness of the molded silicone is usually 30°C-70°C. The process is relatively simple and is applicable to all silicone products.

2. Injection molding: This process has relatively high quality requirements and is a combination of liquid silicone and plastic. Its products are characterized by good thermal stability, cold resistance, excellent electrical insulation performance, and no toxic substances will be produced when burned. Therefore, it has become an irreplaceable material in the production design of household products, automobiles, baby products, medical products, diving products, kitchen utensils and seals.

3. Extrusion molding: Extruded silicone products are usually formed by extruding silicone through an extrusion machine. Generally, the shape of extruded silicone is long, and the tubular shape can be cut at will. The shape of the product made by extrusion is relatively simple. Mostly strips. Silicone accessories Silicone tubes are widely used in the fields of medical and mechanical equipment. It can also be used as a cache in packaging materials.

4. Calendering: Silicone rubber is kneaded and kneaded with white carbon black, silicone oil, etc. to make a mixed rubber, and then calendered to produce a sheet. The physical and mechanical properties of the film produced by calendering have obvious differences in the longitudinal and transverse directions, and this phenomenon is called the calendering effect. Specifically, the tensile strength of the film in the longitudinal direction is greater than that in the transverse direction, the elongation at break in the transverse direction of the film is greater than that in the longitudinal direction, and the shrinkage rate in the longitudinal direction of the film is greater than that in the transverse direction. The calendering effect is the result of the orientation of macromolecules and needle-like and sheet-like compounding agents in the rubber compound along the calendering direction during the calendering process. The size of the calendering effect is related to the composition of the rubber material, calendering temperature, speed, speed ratio, etc. For larger products, such as silicone sheets, silicone plates.

5. Pouring: The operation method of filling mold or filling mold: filling mold or filling mold is used for relatively smooth or simple products. There is no mold line to save labor and time. It is to use the rubber plate to copy the product or model you want to copy. Or surround it with a glass plate, pour the vacuumed silica gel directly on the product, after the silica gel is dried and formed, take out the product, and the mold will be formed (Note: The perfusion mold is generally made of soft silica gel, so the demoulding It is relatively easy and will not damage the product inside the silicone mold). It is a combination of solid and liquid, such as mobile phone cases, luggage cases, etc.

6. Coating: rapid vulcanization, strong adhesion, good fluidity, and easy degassing. Catalyzed by platinum complex, non-toxic and odorless; excellent thermal stability and cold resistance (use temperature -60 ° C ~ 200 ° C), good air permeability, heat resistance, and certain tensile strength after molding; non-slip Excellent performance; no pollution; low hardness; planting glue is firmly bonded. High tear strength; high transparency; good tensile properties. Wear-resistant, washable, high temperature resistant; high three-dimensional layer, smooth, soft, flexible fabric with excellent texture, good elasticity, washable and dry cleaning resistant. Applied to the cloth, it has anti-aging effect. Such as silicone gloves, rain boots and so on.
