According to the classification of the production technology of labor insurance shoes: mainly injection molding and cold adhesion two categories.
Injection molding is also a machine made of labor protection shoes. After the face is stuck on the aluminum last, it is generally injected directly into PVC, TPR and other materials by the turntable machine, forming a sole at one time. There is also a PU(chemical name polyamine) injection molding(machines and molds are not the same as ordinary injection molding). Injection molding shoes, also known as injection molding technology, its bottom production technology and molding technology are roughly the same, this process of shoe production, high production efficiency, rubber bottom can wear resistance, insulation. This process is suitable for the production of civilian, tourism, labor insurance and other shoes.
Cold adhesive is what we generally say hand-made insurance shoes, generally need cold adhesive pipeline processing. The practice is to help the face with plastic last shape and the sole with glue stick together. Cold sticky shoes are non-hot sticky shoes. Italian and Spanish shoes belong to this category. Cold and sticky soles are generally provided by the factory responsible for playing soles. If they do not have a mold for soles, they need to be opened separately.
Differentiation method: the most obvious feature of the difference between cold adhesive and injection plastic shoes is that the sole, injection plastic shoe heel or edge has a line, that is because the shoe leaves the mold. And the cold sticky sole is in the face and the sole of the adhesive side, so it is not visible.
