O-ring is a common seal. Its production is the same as most seals. Today, Xiaobian will share with you two O-ring forming methods.
1. Molding method: This is a relatively "old" method, so it has certain disadvantages. For example, due to the method of pre-weighing the rubber material, it will lead to a lot of waste and the vulcanization cycle will last a long time. It was replaced by the method of rubber injection.
2. The rubber injection molding method is the most commonly used method at present. The general process is that the preheated rubber is injected into the mold through an injection molding machine, and then vulcanized and molded. This method has the advantages of short vulcanization cycle, rapid It has the characteristics of less edges and high production efficiency.
