What are the production processes of traditional shoes
(1) Seam craft
This is the traditional processing technology of 5261 Chinese shoemakers and the 4102 manufacturing technology of high-end shoes. 1653 is characterized by stitching with "threads", which refers to the combination of the upper and sole of the shoe by manual or mechanical stitching of ramie and nylon threads.
(2) Adhesive process
It is a new process developed in the 1960s. Adhesive method of shoemaking is a new technology of shoemaking process. It has the characteristics of labor-saving, material-saving, high-quality and high-yield. The outstanding point of this process is assembly production, which is bonded with glue, which refers to the strong glue used for forming the bottom. , Through mechanical air (oil) pressure bonding into shoes.
(3) Vulcanization process flying woven square dance shoes
That is, through the vulcanization process, the rubber is cross-linked and modified to achieve the purpose of enhancing the physical properties of the rubber compound and increasing the service life of the rubber product. This process is one of the methods widely used in the industrial production of rubber shoes.
(4) Injection (extrusion) molding process
This process is characterized by mechanized production, which means that a bottom-shaped mold made of steel (aluminum alloy) is automatically injected into the mold with a quantitative amount of plastic through an injection molding machine, and it is bonded with the upper surface to form a shoe after high temperature thermal plasticization.
(5) Molding process flying woven square dance shoes
This process is characterized by high-temperature pressing with a mold, that is, a bottom-shaped mold made of steel (aluminum alloy), a quantitative raw rubber is placed in the mold, and the shoe upper is placed on the aluminum last, and then placed on the rubber. Pressurization and heat treatment make the rubber vulcanized and the upper rubber compound.
