Mass production of footwear requires cutting every type of shoe material. Shoe leather, fabric, foam, and reinforcing materials must all be cut into the shoe pattern shapes. While there are many new technologies for cutting shoe materials such as a laser, water jet, and CNC drag knife; the steel rule cutting die is still the most common for footwear production.

Making footwear cutting dies
The cutting die maker starts with the cut paper pattern templates of the shoe pattern. The worker will then bend the rule steel into shape using the paper pattern as a guide.
The worker uses a special bench that will help bend the metal. The bench has a foot-operated anvil that moves the tool head to make the bends. A skilled worker can make each cutting die outline in just a few minutes.
The final operations to make the shoe cutting dies include coating it with rust proof paint and a final check to make sure the cutting edge is very sharp. While there are many operations required to make shoe cuttings dies the production is fast, the materials and labor are relatively inexpensive. For small orders, a cutting die fee may be charged by the shoe factory, but usually, the cost of the cutting dies are accounted for the LOP (labor, overhead and profit) charges.
What is Tungsten Carbide Nozzle?
Cemented carbide nozzle is made of precision machinery and cemented carbide material (superhard alloy). The bending resistance is 2300n / mm and the hardness is hra90 degree. When machining cemented carbide nozzle, we achieve precision grinding and surface treatment to achieve the hole roughness of ra0.1 and the roughness of both ends of R is Ra0.025. There is a scientific radius of curvature design at the two entrances. This design ensures the smooth passage of the thread. Due to the whole material processing, there is no elevation angle on the drilling hole, and the bending and blocking phenomenon has been improved compared with ruby nozzle. Cemented carbide nozzle is made by hot pressing and sintering hot straight hole and hill hole. Because of its hardness, low density, excellent wear resistance and corrosion resistance, cemented carbide nozzle has been widely used in sand blasting and shot peening equipment, which ensures that the product can be used in the best air and abrasive for a long time.
advantages
Advantages of cemented carbide nozzle: corrosion resistance, long service life, excellent performance, high cost performance, not easy to wear.
Carbide nozzle and other nozzles: common nozzle materials include cast iron, ceramics, tungsten carbide, silicon carbide, boron carbide. Ceramic nozzles are only used in non aggressive light equipment and abrasive in explosion cabinets. Tungsten, silicon, and boron carbide are the most popular blasting applications due to their long service life. The following is a list of
The shape of nozzle hole of cemented carbide determines its air flow pattern. The nozzle generally has a straight hole or a limiting hole, a hill hole.
1. Straight hole (cemented carbide nozzle 1): the straight hole nozzle forms a sealed air flow mode for on-site or internal air flow. This facilitates the realization of small tasks, such as cleaning parts, weld forming, cleaning handrails, steps, plaques, or stone carvings and other materials.

is made of sharpened rule steel then coated with rust proof paint and marked with the shoe size and model number. Making a shoe requires hundreds of dies. One die for each part, for every size of a shoe. For high volume shoe production, the shoe factory may need many sets of cutting dies.Making footwear cutting dies
