How to improve the service life of Moulds - wire drawing Moulds

Hard alloy Moulds are made of hard alloy. Hard alloys belong to the tungsten cobalt class of alloys, and their main components are tungsten carbide and cobalt. Tungsten carbide is the "skeleton" of alloys, mainly playing a hard and wear-resistant role; Cobalt is a bonding metal and a source of alloy toughness. Therefore, compared with alloy steel Moulds, hard alloy Moulds have the following characteristics: high wear resistance, good polishing, low adhesion, low friction coefficient, low energy consumption, and high corrosion resistance. These characteristics make hard alloy drawing Moulds have a wide range of processing adaptability and become the most widely used drawing Mould today.

Hard alloy wire drawing die is an important Mould for producing metal wire, and its quality directly affects the quality of the wire, the loss of the die, and the economic benefits of product production. In the quality of wire drawing dies, in addition to the material of the Mould core, the perpendicularity of the Mould hole center and the Mould outlet end, the hole structure of the Mould hole is an extremely critical factor affecting the quality of the wire drawing die. The hole structure and dimensions of each part are key parameters for the quality of the Mould. If the hole structure does not meet the design requirements, it will seriously affect the lifespan of the Mould and the drawing speed of the wire drawing machine. This requires the Mould manufacturer to timely grasp these parameters during the production process in order to make necessary grinding corrections and improve product quality.
