Large-scale Vulcanizing Machinery(Vulcanizer)

Large-scale Vulcanizing Machinery

Manufacturing of rubber products requires the heat processing of crude rubber. This process is called vulcanization. Vulcanization of large-scale rubber products requires vulcanizing machinery (vulcanizers) that can store them. We possess one of the largest class vulcanizing machinery in Japan (φ5,200mm diameter, 15,000 mmL) allowing us to manufacture rubber products, which include large diameter rubber expansion joints, condenser water box covers, and large tanks.
