Silicone sealing rings are very common in our daily lives. They may seem small in size, but their function is very significant. It can play an important role in the sealing and preservation of some products. Do you know how it is transformed from silicone raw material into individual silicone sealing rings? It is mainly formed by molding, injection molding, and injection molding.

Compression molding: Commonly used compression molding methods are used to manufacture silicone sealing rings with complex shapes such as leather bowls and sealing rings. The rubber material is placed in the mold and heated to form with the help of molded female and male molds.

Injection molding: Used for more complex silicone sealing rings, such as tire treads, rubber hoses, and metal wire surfaces that need to be coated with glue and manufactured by injection molding. It is a method of continuously shaping rubber compounds with certain plasticity by placing them into the hopper of an extruder and squeezing them through various mouth shapes (also known as templates) under the pressure of the screw. Before extrusion, the rubber material must be preheated to make it soft and easy to extrude, thus obtaining a smooth surface and accurate size silicone sealing ring.

The above are some molding methods for silicone seals. If you know more about silicone seals, please feel free to contact us!
