[0002] Diamond film coated wire drawing die is a high-end precision machining tool designed for the drawing and forming process of metal wire. The uniqueness of this die is that its inner surface is coated with an extremely thin and hard diamond film, which gives the die extraordinary wear resistance and low friction characteristics, greatly optimizing the wire drawing process. Core features: · Extremely high hardness: Diamond is the hardest substance in nature. Its film coating significantly improves the hardness of the die surface, and its ability to resist wear far exceeds that of traditional dies, extending the life of the die. · Low friction coefficient: The coating surface is smooth, which reduces the friction between the wire and the die during the wire drawing process, not only reducing the wire drawing resistance, but also reducing the wire damage, and improving the surface quality and dimensional accuracy of the finished wire. · Improve wire quality: It is suitable for the production of high-precision wires, such as fine and high-purity metal wires required in electronics, medical, aerospace and other fields, ensuring the smoothness, roundness and uniformity of the wire. · High temperature resistance: Diamond film has good thermal stability and can maintain excellent performance even in high-temperature wire drawing operations, suitable for high-intensity production environments with continuous operations. Environmental protection and energy saving: Reducing friction and resistance during the wire drawing process means reducing energy consumption and reducing the use of lubricants, which is environmentally friendly. Scope of application: Widely used in the drawing of various types of metal wires, including copper, aluminum, stainless steel, precious metals and their alloys, especially in the production of fine wires, high-precision wires, optical fiber preform rods and other products with extremely high requirements. Diamond film coated wire drawing dies are indispensable.
