Silicone products made from environment-friendly silicone raw materials are various and widely used in food, medical, electronics, industry, textile and other industries. They are all produced by machines. The difference lies in the different shapes and processes of products. There are four molding methods for silicone raw materials: extrusion, molding, dripping and injection molding. The following is mainly about the extrusion process of silicone products:

Extruded silicone rubber products are usually formed by extruding silicone rubber by extrusion machine. Generally, the shape of extruded silicone rubber is long, and the tubular silicone rubber can be cut at will. It is widely used in medical devices and food machinery. Generally, the most common silicone products are silicone rubber tubes, silicone sealing strips, silicone sealing rings and other silicone products.

Advantages of silicone rubber extrusion molding:

1. The silicone rubber material is further mixed and plasticized through the rotation of the extruder screw,

Ensure that the quality of extruded semi-finished rubber is more dense and uniform;

2. It has a wide range of applications,

It can extrude silicone rubber profiles with various section shapes and preformed semi-finished products for pressing moulds;

3. Extruded products have high speed and production efficiency, which is conducive to automatic production;

4. Extrusion molding is not limited by length, which can meet the requirements of ultra-long products that can not be molded due to equipment limitations.
