Wire drawing die introduction

　　In metal pressure processing, the metal is forced through the die under the action of external force, the cross-sectional area of the metal is compressed, and the tool to obtain the required cross-sectional area shape and size is called a wire drawing die. The wire drawing die is a very important consumable die for various metal wire manufacturers (such as wire and cable factories, steel wire factories, welding rod and wire factories, etc.) to draw wires. The application range of the wire drawing die is very wide, mainly used for drawing straight 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. Since the cost of wire drawing dies accounts for more than 1/2 of the wire drawing cost, how to reduce the cost of wire drawing dies and improve their service life is an urgent problem for metal wire production units to solve.
