The production process of shoes is good, both glue and injection molding have their own characteristics.
The adhesive shoe process, also called cold bonding process, is a process that uses adhesive to connect the upper, insole, and outsole together. Due to the different materials of the upper and sole adhesive surfaces, the types and properties of the adhesives used are also different, such as neoprene adhesives, polyurethane adhesives, SBS adhesives, etc.
Due to its simple process, short production cycle, high production efficiency, low manufacturing cost, rapid changes in color and variety, and easy expansion of reproduction, the gluing process is the most widely used assembly process in the shoemaking industry, accounting for 80% of the total shoemaking products. %above. This process is most commonly used in leather shoes and sports shoe products.
Injection molding, also known as continuous upper injection molding process, is a process in which molten plastic is injected into the outer mold and bonded to the upper. The materials of the outsole are mostly polyvinyl chloride, thermoplastic polyurethane, thermoplastic rubber, etc.
The process is to complete the upper and bottom bonding and assembly under the conditions of automatic feeding, automatic plasticizing, automatic metering, automatic injection, automatic mold closing and opening, and automatic molding, so it has the advantages of high production efficiency and automated production. It is used in the production of leather shoes, cloth shoes, sports shoes, and plastic shoes.
