Labor insurance shoes are mainly used for foot safety protection. The selection should be based on the nature and degree of the hazard of the working environment. Some protective labor shoes must have a product certificate and product manual. In the production of labor insurance shoes, according to its process, it can be divided into two categories: injection molding and cold bonding. In order to let everyone better use labor insurance shoes, today we will introduce some differences between injection molding and cold adhesive labor insurance shoes.
1. Injection
That is, the machine-made labor protection shoes. After the upper is tied to the aluminum last, the turntable machine usually directly injects PVC, TPR and other materials to form the sole at one time. Now there are PU (chemical name polyurethane) injection molding (machine and mold heel). General injection molding is not the same). The advantages of injection molding production are large output and low price. But if there are many styles, it is not only troublesome to change the mold, but also difficult to shape the shoes, so it is generally suitable for orders with a single sole style.
2. Cold stick
It is the hand-made labor protection shoes that we generally say. Italian and Spanish brand-name shoes belong to this category. Generally, cold sticky assembly line processing is required. Generally, the sole factory is free to open the mold for more than 2w pairs. The method is to use plastic last to shape the upper surface and glue it together with the sole. Advantages: The workmanship is fine, and the shoes made are better. Disadvantages: The daily output is small, the price is high, and it is generally suitable for production in medium-sized and above factories to form a scale.
3. Resolution method
The most obvious difference between cold-bonded and injection-molded labor protection shoes is the sole. The injection-molded shoe has a line on the heel or edge, while the cold-bonded sole is on the side where the upper and the sole are bonded, so it is invisible .
