Drawing die use widely, such as electronic devices, radar, television, instrument and aerospace high precision wire and commonly used tungsten wire, molybdenum wire, stainless steel wire, wire and cable wire and all kinds of alloy wire with diamond wire drawing die drawing, diamond wire drawing die due to the use of natural diamond as raw material, which has very strong wear resistance, the service life is very high.

Drawing die is all kinds of metal wire manufacturers (such as wire and cable factory, steel wire factory, electrode wire factory) of the drawn wire a very important consumption of mould. The application of drawing die is very wide, mainly used in drawing bar, wire, wire, pipe and other linear difficult to process, suitable for steel, copper, tungsten, molybdenum and other metal and alloy material drawing processing. Because the cost of drawing die is about 1/2 of the cost of drawing, so how to reduce the cost and improve the service life of the wire rod is an urgent problem to be solved in the production of metal wire.
