Silicone Rubber Manufacturing Process

Common molding methods of rubber compound

01
Compression Molding

A production model in which the rubber is put into a mold cavity and placed between the upper and lower plates of a flat vulcanizing machine, and pressure, temperature, and time are given under certain conditions to complete the mold after vulcanization.
02
Extrusion Molding

It is a method of continuously forming rubber material through a certain shape of dying under the extrusion of the extruder screw. This method is used for rubber hose, wire coating, and cable sheath.
03
Secondary Sulfur Addition

Secondary sulfur addition refers to post-stage vulcanization, which is generally carried out in an oven. The first purpose is to remove residual decomposition products of vulcanizing agents in products; The second is to keep the products in good thermal stability when in use.

SILICONE RUBBER APPLICATIONS

01
Industrial
Silicone rubber has good weatherability and constructability and has a wide range of applications, such as in the construction industry. As an adhesive sealant, it has been widely used in the construction industry, surpassing other types of sealants.
01
Medical
Medical silicone rubber can be used in intravenous catheters, gastric tubes, urinary catheters, etc., with light damage and little irritation to the human body, and can be inserted into relevant parts of the human body for a long time and it has been widely used in the clinic.
01
Automotive
The automotive industry is defined by constant evolution. Finding ways to improve fuel economy and reduce emissions, while enabling improvements in safety and performance, are just some of the areas Genvan working on every day. As populations grow, and the globe economies develop and improve their transportation infrastructure, Genvan technologies help the world move forward with enhanced functionality, safety, and sustainability.
01
Electronics
Electronic silicone rubber is mainly used in the bonding, sealing and potting of electronic products.
01
Domestic Products
Because of its high and low-temperature resistance( which can be used at-40-230 degrees, is made of soft material, good stability, resistance to falling and deformation, non-stick to the pan, easy to clean, etc., and is widely used in daily life. Household silicone is a new breakthrough for traditional kitchen utensils, such as baking tray mats, cake baking trays, elastic baking trays, and baking tray molds...
