Solid Silicone Rubber-Compression Molding
Heat-curable, high-temperature-vulcanizing (HTV) elastomers are higher viscosity rubbers that are mixed and processed like other elastomers. They are cured at elevated temperature, either by means of organic peroxides or with platinum catalyst.
After mixing, use the cutting machine to cut the material into the appropriate size and thickness of the product, and then put it into the mold, molding at a certain temperature. Release after complete vulcanization. The hardness of Silicone rubber mold is (Shore hardness) 30-70A.
Characteristics of Solid Silicone Rubber
It is formed under high temperature of vulcanizing agent, and made into various silicone rubber articles for daily use, industrial miscellaneous parts, auto parts and other products, with good physical properties.
After the secondary vulcanization, the product can generally pass the FDA test and reach the food grade standard. Must be heated and vulcanized at high temperature.
Product Advantages and Disadvantages
Low transparency and smell of vulcanizing agent or other covering vulcanizing agent.
There are parting line and flash on products, need to manually remove flashing.

Liquid Silicone Rubber-Injection Molding
Liquid silicone rubber LSR (Liquid Silicone Rubber) is a product that can be favored by consumers and manufacturers. Liquid silicone is made of silicone products, which is stretchy, waterproof and dampproof, acid-resistant and alkali-resistant. So it is generally used to replace daily plastic products.
Inject liquid silicone into the mold to make silicone products, which can achieve the advantages of one-time molding, no waste, and automation.
Characteristics of Liquid Silicone Rubber
It is liquid and easy to form, which can quickly realize massive production and greatly improve production efficiency. It is very suitable for baby supplies, kitchen supplies, medical supplies, automotive supplies and other fields.
According to the processing technology, it can be divided into two types: condensation type and addition type. Condensed silicone rubber generally does not meet food-grade standards, and the environmental protection level of addition-molded silicone rubber can exceed food-grade certification standards. Both can be vulcanized and molded at room temperature.
Product Advantages and Disadvantages
High environmental protection grade, high transparency, no peculiar smell, easy to process.
The product have a gate.
