The main function of the silicone ring is to form a seal between two parts to prevent liquid or gas leakage, and it also plays a role in fixing and guiding.

[0003] The production process of silicone rings is relatively simple, and is mainly divided into the following steps. The first step is to process the silicone raw materials. Silicone raw materials usually have two forms, one is liquid and the other is solid. To make silicone rings, the silicone raw materials must be fully mixed and stirred to ensure uniform composition. The second step is to make a mold, which needs to be made according to the specifications of the silicone ring.

[0004] After the mold is made, the silicone ring can be injected. That is, the prepared silicone raw material is gradually injected into the mold through the feeding mechanism, and the silicone fully fills the gap inside the mold to shape the silicone ring.

[0005] In the existing feeding mechanism, most of the silicone rings of one specification correspond to one mold, and only one mold can be filled at one time, which has low production efficiency. After the prepared silicone raw materials are poured into the raw material barrel, no stirring and insulation structure is set, which causes the raw materials to condense during the feeding and injection molding process, affecting the discharge speed and the subsequent molding quality of the silicone rings.
