At present, the production processes of safety shoes that consumers often come into contact with are mainly divided into two categories: injection molding and cold bonding. Injection molding is the introduction of the shoes produced by Desmar Lianbang injection molding machine. After the upper surface is tied on the aluminum last, the PU (chemical name polyurethane) material is directly injected by the turntable machine to form the sole at one time. Advantages: Since it is mainly made by machine, if the output is large, the price will be cheaper, and the quantity is small, and vice versa. Disadvantages: If there are many styles and the number is small, it is very troublesome to change the mold, the shoes are difficult to shape, and the workmanship of the cold-adhesive shoes is not exquisite, so it is generally suitable for orders with a single sole style.

Cold sticky shoes are also often referred to as handmade shoes, and shoes from Italy and Spain belong to this category. Generally, it is processed by a cold-bonded assembly line, and the cold-bonded soles are generally provided by factories specializing in the production of soles. The practice is to use plastic last to shape the upper surface and glue it to the sole with glue. Advantages: fine workmanship, the shoes made are better. Disadvantages: The daily output is small and the price is high. Generally, only medium-sized and above factories can produce scale.

Difference method: The obvious feature of distinguishing cold-bonded and injection-molded shoes is the seam between the sole and the upper surface. The cold-bonded labor insurance shoes have 360-degree stitching. Generally, the material of the outsole is natural rubber, relatively speaking It is relatively heavy and has good anti-skid performance, strong oil resistance, acid and alkali resistance, and the injection molding shoes are PU soles, which are relatively light, but cannot be soaked in water, and are suitable for places where the working environment is relatively clean.

The components of the shoe: It is mainly composed of the upper surface, the inner lining (lining), the front and rear ironing soles, the front and rear toe caps, the midsole (also called the inch sole), the sole and other parts.

Help surface: The material is generally leather (LEATHER) or artificial leather, etc. The leather material is uneven, the good one is the first layer of leather, soft in texture and good elasticity. Generally speaking, the shoes made of soft sheepskin are better. There are many kinds of artificial leather, most of them are PU leather, the thickness is in silk, generally 80 silk, good can reach 140 silk, suitable for the production of single-layer upper surface (without compound lining), comfortable to wear, especially in Korea shoes, generally do. In recent years, the popular PU leathers include rubbed leather, rubbed leather, bubble pattern, crazy horse pattern, size pattern, nappa pattern, R8 pattern, 18 pattern and many other patterns. Because Crazy Horse leather has a texture like real leather, and the effect is good, it is very popular at present, but the price is very high. Rubbing glue is a classic leather, which has been popular for more than 10 years. Now there are many kinds of glue, and the effect of rubbing is different. The color is dark or light, and it has a lot to do with the wax used. The price is moderate, but The workmanship is difficult, and generally requires a special gluer to wipe it well. Now there are also imitation cowhide leather, the thickness of which is more than 200 silk, and the price is extremely high.

Lining and ironing: The material is generally leather, PU, ​​PVC, etc. The upper surface of the leather is generally equipped with a leather lining, which is comfortable to wear, has good heat dissipation, and is not easy to cause “Hong Kong feet”. But the price is more expensive!

The sole will be an important part of the shoe, there are PU sole, TPR sole, PVC sole, MD sole, combined sole. The advantages of PU soles are light weight, soft texture and good hand feeling. Many customers in the Middle East and Europe like the sole made of PU material, and the introduction of Desmar Lianbang injection molding machine is also very popular due to the large output and low cost of the machine. TPR soles are moderate in weight and have a certain degree of softness, but the production process is more complicated than that of PU soles, and there is no peculiar smell. The price of PVC soles is cheap, and they are usually injected directly in the factory, but the cold-bonded soles are also made of PVC materials. The texture can be adjusted by pre-molding, which can be hard or soft, but the PVC soles are somewhat odorous because they are plastic materials.

Other parts, such as the midsole, are just the layer between the sole and the upper, and the material is single, so I won’t talk about it here. Baotou is divided into cardboard toe and steel toe, in millimeters, ordinary shoes generally use 1.7mm cardboard is already very good. It is mainly used on the toe and heel to make the leather shoes look sharp and angular, and play the role of reinforcing the shoe shape (the steel toe cap is used for the toe shape of the labor insurance shoe).
