What material is Zhongshan shoe mold made of?

Aluminum. Shoe molds usually refer to molds for sports shoes and sandals, slippers, rubber shoes and other footwear, among which sports shoes are the main ones. Mold refers to all kinds of molds and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, melting, stamping and stretching.

The trend of sports shoes is not only to pay attention to shape design and fashion, but also to its function and comfort. Especially in the sole part, major brand-name sports shoes manufacturers spare no effort to invest in research and development and innovation. Therefore, the sole mold factory is facing the demand of changing the free-form surface of shoes, shortening the product life cycle and improving the quality. In order to meet the market demand, the design and manufacturing technology of sole mold must be greatly improved.

Generally, the sole materials of sports shoes include: RB (rubber), RS (foamed rubber), TPR (thermoplastic elastomer), EVA (ethylene-vinyl acetate * * * polymer, including IMEVA injection EVA and CMEVA traditional secondary molding EVA), PU, TR, BR, TPU, PVC and so on. Due to the continuous development of modern science and technology, many new materials are being applied to the research and development of soles.

Sole molds need different designs because of different materials. Among them, RB, EVA, TPR and other main materials are the most widely used molds. Generally speaking, shoe molds are injection molds, but there are some exceptions. For example, the production process of CMEVA is a combination of injection molding and cold pressing, and some are blow molding.
