Ruishi diamond wire drawing die blank is made by sintering diamond micro powder under various metal (including cobalt) catalysts using ultra-high temperature and ultra-high pressure processes. During the sintering process, high-strength diamond bonds are formed between diamond microcrystals, which strongly bind diamond micro powder particles together to form polycrystalline diamond (PDC). The diamond wire drawing die blank manufactured with this material has good toughness, wear resistance, thermal conductivity, hardness, and mechanical strength, and is suitable for drawing non-ferrous metals such as copper, aluminum, nickel, stainless steel, and various alloy wires.

This product is divided into two series, RS series and TRS series.

Among them, the RS series is divided into the RSH series and the RSR series. This specification of wire drawing die blank is suitable for various types of wire drawing applications, especially for wire drawing molds with high consumption due to its low price.

The TRS series is a wire drawing die supported by a hard alloy ring. Its characteristic is that the polycrystalline diamond core is tightly sintered with the hard alloy support ring to improve the crack resistance strength of the die blank. Therefore, this type of product can withstand high strength and high speed drawing.
