What are the processes of silicone rubber products?
Silica gel products began to be used in more and more fields. It is precisely because of its non-toxic, odorless and high temperature resistance that determines its application field. Different silica gel products have different manufacturing processes.

Molding
Molding, this manufacturing process is the most common. It is mainly accomplished by the cooperation of the die. The shape of the die decides the shape of the silica gel product. Molded silica gel products are usually formed by high temperature moulds after adding solid silica collagen with vulcanizing agent and applying pressure through the vulcanizing machine. The hardness of moulded silica gel is usually 30 ~70 ~C. This process is simple and suitable for all silica gel products.

injection
This process is a combination of liquid silica gel and plastic with high quality requirements. Its products are characterized by good thermal stability, cold resistance, excellent electrical insulation performance, and no toxic substances are produced when burning. Therefore, it has become an irreplaceable material in the production and design of health supplies, automobiles, baby supplies, medical supplies, diving supplies, kitchen appliances and seals.

Squeeze
Extrusion molding, extruded silica gel products are usually extruded by extrusion machine. Generally, the shape of extruded silica gel is long, the tubular shape can be tailored at will. The shape of extruded products is relatively single, mostly strip. Silicone tube is widely used in the field of medical treatment and mechanical equipment. It can also be used as a buffer in packaging.

Calendering
Silicone rubber is kneaded and blended with silica and silicone oil to form a blend and then rolled out. The physical and mechanical properties of the rolled film are obviously different from those of the transverse film. This phenomenon is the calendering effect. Specifically, the longitudinal tensile strength of the film is greater than that of the transverse, the transverse elongation of the film is greater than that of the longitudinal, and the longitudinal shrinkage of the film is greater than that of the transverse. Calendering effect is the result of orientation of macromolecule and acicular and flaky compound along calendering direction during calendering process. The calendering effect is related to the composition of the compound, calendering temperature, speed and speed ratio. For larger products, such as silicone film, silicone board.

perfusion
The operation method of the filling or pouring mould: the filling or pouring mould is used for relatively smooth or simple products. Without the moulding line, it saves labour and time. It is to surround the product or model you want to copy with a rubber or glass plate, and pour the vacuum-pumped silica gel directly onto the product. After the silica gel is dried and formed, the product is taken out. It is a combination of solid and liquid, using products such as cell phone sleeve, luggage case, etc.

Coating
Rapid vulcanization; strong adhesion; good fluidity, easy to defoam. Using platinum complex catalysis, non-toxic, odorless; excellent thermal stability and cold resistance (using temperature - 60 ~200 C) after molding has good air permeability, heat resistance, and a certain tensile strength; excellent anti-slip performance; non-pollution; low hardness; strong adhesive planting. High tear strength; High transparency; Good tensile properties. Wear-resistant, washable, high temperature resistance; three-dimensional high level, smooth, soft, flexible texture, good elasticity, water and dry cleaning resistance.  When applied to cloth, it has anti-aging effect. For example, silicone gloves, rain shoes, etc.
