Vulcanized Shoes Making Process

It is the process method of heating, pressurizing and vulcanization in the autoclave after gluing the outsole, along the strip and the top of the first-class film with the upper. The outer end of the process is divided into a die-free (calendering) molding and molding.Vulcanized shoes 

Because the process is relatively rough, not easy to control quality, usually can only produce low-grade products. In recent years, due to the introduction of foreign advanced production technology, product grade has been greatly improved. Because of the comfort and economy of vulcanized shoes, high efficiency and low cost at the end of the production, this process is still used in the production of cloth shoes and rubber shoes as well as leather shoes.Vulcanized shoes

The structural characteristics of vulcanized shoes: vulcanized shoes, is the outsole and surrounding strips, such as raw film shoes and the upper and the bottom adhesion, in the autoclave in the pressurized heating and vulcanization molding footwear products. Before assembly, the upper and the bottom have been stitched together, the outsole, surrounding strips and other raw film has been rolled and cut molding. In the assembly, the upper sleeve into the hollow aluminum to form a shoe shape, and then in the relevant bonding surface after the brush adhesive is beginning to adhere to the bottom, Sticky wai, sticky outsole and other raw film, after renovation hung on the vulcanization car.Vulcanized shoes

In the vulcanization, the vulcanization car will be pushed into the shoe with a vulcanizing tank, in its confined space through steam heating, heat preservation, compressed air boost, holding pressure vulcanization process, the outsole and other raw film that vulcanization molding and with the upper bonding as a whole. Vulcanized shoes with simple structure but rough process, no molding but easily deformed, in the production of high efficiency, low cost, wearing a lightweight comfortable, economical and durable characteristics. Vulcanized shoes in leather products although has been gradually phased out, but in cloth shoes and other products still mass production.Vulcanized shoes

Vulcanization Shoe Assembly Process Description: The assembly process of vulcanized shoes is basically manual operation, the use of simple tools and tooling, the main shoe equipment is the shoe vulcanizing tank. pressure, temperature and time are three important conditions for vulcanized shoes. Pressure in the autoclave, vulcanization time. Vulcanization shoe can be removed when vulcanizing shoe is formed and is in the condition of no pressure in the vulcanization tank. Vulcanized Shoes of the rubber processing equipment and molded shoe plastic processing equipment is basically the same, mainly have the former help machine, cutting machine, mixer, open refining machine, press base machine, cutting machine.Vulcanized shoes
