The quality and manufacturing process of the wire drawing die. China is a big wire producer and its output ranks among the top in the world. China's polycrystalline mold manufacturing industry has developed rapidly since the 1980s. With the continuous improvement of the manufacturing level of drawing die and the continuous improvement of production technology, China's polycrystalline mold manufacturing technology has further developed, especially in the drawing die. Material, structure and other aspects have made great progress. But in general, there is still a big gap with foreign countries. Although the types of wire drawing molds produced in foreign countries are similar to those in China, the materials and processes used are more advanced. The processing precision, durability and wear resistance of wire drawing dies are superior to those of our products. Therefore, strengthening mold management, improving the quality level of polycrystalline molds, and promoting the advancement of mold making technology are important issues currently facing the molding industry.

In order to improve the competitiveness of production, the foreign metal products industry pays more and more attention to the quality of the drawing die and the improvement of the manufacturing process. Starting from the improvement of the life of the wire drawing die, the material, structure, manufacturing process, manufacturing equipment and testing instruments of the polycrystalline die are carried out. The research of the system developed the composite drawing die, the new material of polycrystalline mold, the new technology of surface coating, and the new hole design method of drawing die, which promoted the development of drawing production in the world.
