①Injection method: With medium injection pressure and high barrel temperature, the synthetic resin plastic is injected into the mold to complete the curing of the sole and the combination of the upper and the sole at one time. Mostly used for cloth shoes. Leather shoes, plastic shoes, and rubber shoes also use this process.
②Gluing injection method: plasticize the rubber through the barrel, and then inject it into the mold with a high injection pressure, and complete the sole making and the sole bonding and molding at the same time. For cloth shoes, rubber shoes.
③Pouring method: A and B components of a quantitative reactive raw material liquid (such as polyurethane, polyamide, etc.) are poured into the mold cavity after mixing at a high speed in the mixing head, so that they can be placed under normal (high) pressure. Curing and forming. Now it is mostly used in the production of rubber shoes and a few cloth shoes.
④Slush molding method: Pour the plastisol into the female mold cavity of boots and shoes, and rotate the mold while heating, so that a part of the plastisol is attached to the cavity wall under the action of centrifugal force and solidifies into a green body, and the excess plastisol liquid is poured out. , continue to heat to make the green body mature and form, and then put it into the lining of the shoe after demoulding. For rubber and plastic shoes.
