Self Supported Diamond

We are a leading company involved in manufacturing, exporting and supplying a wide range of Self Supported Diamond in Zhengzhou, Henan, China.

These have not only high wear resistance, hardness, and thermal conductivity, but also high mechanical strength and tenacity. They are suitable for high-speed drawing of nonferrous wires such as copper, aluminum, nickel, stainless steel and other alloy wires.
RJ Diamond Wire Drawing Die Blanks include two series: CD Series and SP Series. According to the application of wire drawing, each series has 5 grain sizes:3I mi 5I mi 10I mi 25I m and 50I m.

CD Series are self supported PCD die blanks in hexagonal shape (CDH) and round shape (CDR). They are suitable for all types of wire drawing applications especially when cost-cutting is required.

SP Series are tungsten carbide supported PCD die blanks in round shape. TC ring enhances tearing strength of die blanks, which is especially suitable for high strength and high speed wire drawing.
