Die refers to the industrial production used in injection, blow molding, extrusion, die casting or forging molding, smelting, stamping, stretching and other methods to obtain the required products of various molds and tools. Usually, shoe mold refers to sports shoes and beach shoes, slippers, rubber shoes and other footwear mold, among which sports shoes mainly.
The trend of sports shoes has not only paid attention to shape design and popularity, function and comfort has also become one of the key points. Especially the part of the sole, the major brand shoe manufacturers have spared no effort to research and development of innovation. Therefore, the shoe mold factory faces the change of free-form surface, the shortening of product life cycle, and the improvement of quality. In order to meet the market demand, the design and manufacturing technology of the sole mold is bound to be greatly improved.
Athletic shoe sole material generally: RB (rubber), RS (foamed rubber), TPR (thermoplastic elastomer), EVA (ethylene - vinyl acetate copolymer, including IMEVA injection molding EVA and CMEVA traditional secondary molding EVA), PU, TR, BR, TPU, PVC, etc. Due to the continuous development of modern technology, many new materials are being applied to the research and development of sole.
The sole mold needs different design because of the different material. Among them, RB, EVA, TPR and other major materials are the most widely used molds.
