According to the production process of anti-static safety shoes, there are two main categories: injection molding and cold bonding.
Injection molding is machine-made anti-static safety shoes. After the upper is tied to the aluminum last, PVC, TPR and other materials are usually injected directly by the turntable machine to form the sole at one time. Now there is also PU (chemical name polyurethane) injection molding (machine And the mold is different from general injection molding). Advantages: Because it is machine-made, the output is large, and the price is low. Disadvantages: If there are many styles, it is more troublesome to change the mold, the shoes are difficult to shape, and the cold glue shoes are not exquisite, so they are generally suitable for orders with a single sole style. Cold sticky is what we generally call hand-made anti-static safety shoes. Italian and Spanish brand-name shoes belong to this category. Generally, cold sticky assembly line processing is required. Generally, the shoe sole factory is free to open the mold for more than 2w pairs. The method is to use a plastic last to shape the upper 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.
The injection molding process shoe is also called the injection molding process. The bottom making process is roughly the same as the molding process. This process makes shoes with high production efficiency and low cost. The plastic bottom is resistant to oil and insulation. This process is suitable for the production of shoes for civilian use, tourism, labor insurance, etc.
Differentiation method: The more obvious feature of anti-static safety shoes that distinguish between cold glue and injection molding is the sole, and the injection molded shoes have a line on the heel or edge, which is because the shoes are left from the mold. The cold-adhesive sole is on the side where the upper and sole are glued, so it is invisible.
stitching craft shoes are mostly used in high-end men’s shoes and labor insurance leather shoes, organic stitching and hand stitching. It is characterized by high material selection requirements, complicated process, firm structure, and durability.
Adhesive craft shoes This is a main craft of shoemaking at present. The upper is stretched and glued to the inner sole, and the outer sole is glued with neoprene adhesive. It is not limited by the outsole mold, the color is easy to change, and the product is light-weight, especially suitable for medium and high-end women’s shoes with strong technical skills.
