How to improve the quality of wire drawing dies. In metal pressure processing, a metal is forced through a mold under an external force, and the cross-sectional area of the metal is compressed to obtain the required cross-sectional area shape and size. The tool is called a drawing die. The wire drawing die is a very important consumable die for drawing wires by various metal wire manufacturers (such as wire and cable factories, steel wire factories, welding wire factories, etc.). The scope of application of wire drawing die is very wide. It is mainly used for drawing linear and difficult to add objects such as bars, wires, wires, pipes, etc. It is suitable for drawing processing of metal and alloy materials such as steel, copper, tungsten, molybdenum, etc. Since the cost of the wire drawing die accounts for more than 1/2 of the wire drawing cost, how to reduce the cost of the wire drawing die and increase its service life is an urgent issue for metal wire production units. ——Drawing mold

In order to improve the competitiveness of production, the foreign metal products industry attaches more and more importance to the improvement of the quality of the drawing die and the improvement of the manufacturing process. Starting from the improvement of the life of the drawing die, the material, structure, manufacturing process, manufacturing equipment and inspection equipment of the drawing die are carried out. Based on systematic research, the company has developed composite drawing dies, new drawing die materials, new surface coating technology, and new hole design methods for drawing dies, which has promoted the development of wire drawing production in the world. China is a major wire producer and its output ranks among the highest in the world. China's wire drawing die manufacturing industry has developed rapidly since the 1980s. With the continuous improvement of wire drawing die manufacturing level and continuous improvement of production technology, China's wire drawing die manufacturing technology has progressed, especially in the materials of wire drawing die, Great progress has been made in structure and other aspects, but in general there is still a big gap with foreign countries. Although the types of wire drawing dies produced abroad are similar to those of domestic ones, the materials and processes used are more advanced. The processing accuracy, durability and wear resistance of wire drawing dies are better than those of our products. Therefore, strengthening the management of mold making, improving the quality level of wire drawing dies, and promoting the progress of mold making technology are important issues currently facing the mold making industry.
