Different function of the labor protection shoes we will have different production process in the production process. The general production process of labor insurance shoes is as follows:

1. Traditional cold adhesion process: the safety shoe surface is shaped with a plastic last, then it is roughened by pregrinding, followed by treating agent and potion, and then it is formed with a large bottom with good glue. If the large bottom has groove structure, in order to achieve better prevention of opening glue, a large bottom line along the groove car can be used to strengthen the structure of labor protection shoes. Safety shoes with large rubber soles are generally made of cold adhesive. Advantage: work fine, make the shoe effect is better. Disadvantages: small daily output and high price.

2. Goodyear process: it is a special sole processing technology. With advanced sewing and adhesive technology, the upper and sole are closely combined with the rubber midsole by the edge and the rubber midsole. The edge is then polished and shaped. Cons: complicated, costly and expensive safety shoes.

3. PU injection molding process: after the safety shoe vamp is mounted, it is fixed on the head of the injection molding machine of PU injection molding machine. After pre-grinding and roughing, it is put into the corresponding bottom mold and then injected with liquid PU to solidify and form. Advantage: large output, low price. Weakness: if the style is many, change mould more troublesome. PU injection safety shoes have become one of the more popular methods of labor protection shoes.

Shoe component: the shoe is mainly made up of upper side, inner lining (inside), front and back pressing, front and back covering, middle (also called insole), sole and other parts.
