Injection molding, a technology of pressing molten plastic into a mold and then molding.

Vulcanization is also a treatment technology, which is the process of transforming plastic rubber into elastic rubber or hard rubber, that is, the process of linear polymer forming network polymer through crosslinking.

According to different production processes, there are two kinds of sewing shoes: sewing shoes, rubber shoes, molded shoes, injection shoes, vulcanized shoes ... sewing shoes are mostly used for high-grade men's shoes and labor insurance shoes, organic sewing and manual sewing. It is characterized by high material selection requirements, complex technology, solid structure and durability. Injection molding shoes, also called injection molding process, are basically the same as the molding process. This technology has high production efficiency and low cost, and the plastic sole is oil-resistant and insulated. This process is suitable for producing civil shoes, travel shoes and labor protection shoes. Vulcanized craft shoes, the combination of vamp and midsole, is similar to the formation of sleeve vamp. The sole is not limited by the mold cavity, but the film bottom is cut from the bottom template and bonded to the vamp through high-temperature vulcanization. This is the simplest process, with the highest production efficiency, moisture resistance and slight insulation. Suitable for ordinary daily wear, especially for farmers. The disadvantage is that the formability and moisture permeability of the product are slightly poor.
