1. Plasticizing at a certain temperature through the rubber seal material;
2. Secondary mixing is performed to improve the rubber properties;
3. The polymer material of the rubber seal needs to be made into a billet by extrusion;
4. Pay attention to the amount of interference when cutting rubber materials. When cutting, you can use a punch or a disc knife to cut according to the shape of the cavity;
5. The last step is the molding and vulcanization of rubber seals, which is also the main process of pressing and molding polymer rubber seals.
