The quality of the vulcanized product is qualified. low rate.

The existing rubber air spring vulcanization process mainly uses a capsule as the inner bag. Such as patent CN 102756444A, when vulcanizing the unformed rubber air spring, a rubber capsule is first set in the inner cavity of the molding die of the vulcanization mold, and then the rubber air spring is put into the capsule of the vulcanization mold to be shaped and molded. After closed, the pressure and heat are charged, and the heat is transferred to the rubber air spring through the capsule, and the rubber air spring is heated and vulcanized by the heated capsule. The vulcanization time is generally 30-60 minutes, and the service life of the capsule is 100-350 times.

The disadvantages of this method of vulcanization are: 1. The heat in the vulcanization needs to be transferred to the rubber air spring through the bladder, and a set of special equipment is required to manufacture the bladder. During the transfer process, there will be heat delay and energy waste, resulting in excessive vulcanization time of the rubber air spring. Long, low vulcanization efficiency and serious waste of resources; 2. It needs to consume a large amount of high-quality rubber to manufacture capsules, and it needs to be equipped with a set of special equipment to manufacture capsules, which increases the cost of vulcanization of rubber air springs to a certain extent; 3. Utilization The capsule molds the rubber air spring, which will cause uneven expansion, which will have a certain impact on the life and use of the rubber air spring.
