1. Preparação de matérias -primas: Durante todo o processo de trabalho da máquina de moldagem por injeção de borracha, as matérias -primas precisam ser preparadas primeiro . Isso envolve a preparação de borracha sólida ou peças de borracha pré -formada para o processamento subsequente .
2. Plasticization and injection: These rubber materials are then heated to a softened state by the plasticizing device of the machine, a process called plasticization. The plasticized rubber material has a certain fluidity and is then injected into the mold cavity through the injection device. During the injection process, the parameters such as the pressure, speed, and time of the injection device need to be strictly controlled Para garantir que o material de borracha possa preencher a cavidade do molde e evitar defeitos como bolhas ou injeção insuficiente .
3. Mold closure and vulcanization: After the rubber material is injected into the mold, the mold is closed, and high pressure is applied to form the rubber material into the desired shape in the mold. During this process, the vulcanization reaction begins to occur, and the control of vulcanization conditions (such as temperature, time, and pressure) is crucial to the performance of the final product. The vulcanization Processar reticular o material de borracha para formar uma estrutura de rede, obtendo assim a elasticidade e a força necessárias .
