Six techniques of silicone products
Here are six techniques for silicone products:

I. Molding
Compression molding is the most common manufacturing process. It is mainly completed by the mold. The shape of the mold determines the shape of the silicone product. Molded silicone products are usually made by high-temperature molds after adding solid silicone raw materials with vulcanizing agent and applying pressure through a vulcanizing machine. The high-temperature sulfur is solidified and molded. The hardness of molded silicone is usually 30 ° C-70 ° C The process is relatively simple and suitable for all silicone products.

2. Injection (injection)
This process is relatively high in quality and is a combination of liquid silicone and plastic.
Its products show good thermal stability, cold resistance, excellent electrical insulation properties, and will not produce toxic substances when burning.
Therefore, it has become an irreplaceable material in the production design of health products, automobiles, baby products, medical supplies, diving supplies, kitchen appliances and seals.
Three. Squeeze out
Extrusion molding. Extruded Guangdong silicone products are usually extruded through an extrusion machine. Generally, the shape of the extruded silicone is long, and the tube can be cut freely. Strip. Silicone tube is widely used in medical and mechanical equipment fields. It can also be used as a buffer in packaging materials.

4. Calendering
Silicone rubber is kneaded and mixed with carbon black, silicone oil, etc. to form a kneaded rubber, and then rolled out to form a sheet.
The film produced by calendering has obvious differences in the physical and mechanical properties in the longitudinal and transverse directions. This phenomenon is the calendering effect. Specifically, the longitudinal tensile strength of the film is greater than the horizontal direction, the elongation at break of the film is greater than the longitudinal direction, and the longitudinal shrinkage of the film is greater than the transverse direction.
The calendering effect is the result of the orientation of macromolecules and needle-like, sheet-like complexing agents in the rubber compound along the rolling direction during the rolling process. The size of the rolling effect is related to the composition of the rubber, the rolling temperature, the speed, and the speed ratio.
For larger products, such as silicone tablets, silicone plates.

V. perfusion
The operation method of the filling mold or the filling mold: The filling mold or the filling mold is used for relatively smooth or simple products. There is no mold line to save labor and time, which is to surround the product or model you want to copy with a plastic or glass plate. Then, pour the vacuumed silicone directly onto the product. After the silicone is dried and formed, take out the product and the mold is formed. (Note: The injection mold is generally made of soft silicone rubber. Will damage the product in the silicone mold). It is a combination of solid and liquid, using products such as mobile phone cases, luggage covers, etc.

Six. Coating
Fast vulcanization; strong adhesion; good fluidity and easy defoaming. Catalyzed by platinum complex, non-toxic and odorless; excellent thermal stability and cold resistance (using temperature -60 ℃ ～ 200 ℃) after molding, it has good air permeability, heat resistance and certain tensile strength
Excellent anti-skid performance; no pollution; low hardness; firm glue bonding. High tear resistance; high transparency; good tensile properties. Wear-resistant, washable, and high-temperature resistant; high three-dimensional layer, fabric is smooth, soft, flexible and excellent in texture, good elasticity. Resistant to washing and dry cleaning.
Applied to cloth, it has anti-aging effect. Such as silicone gloves, rain boots and so on.
