Diamond die is a wire drawing tool applied in the production of soft wire products such as copper and aluminum wires, and hard wire products such as stainless steel, tungsten and copper plated steel wires. The main production principle of wire drawing is that the wire is drawn from the big aperture through a small aperture by the hole of the diamond die and utilizes the wire's extensibility, reducing gradually the circumference. The surface of the wire is also raised to its slick level during the production process(As shown below)

To preserve the life of your diamond dies:
1、Avoid shocks to the die when installing. During operation reduce vibrations in the wire and on the drawing machine .
2、Pay attention to the quality of drawing wire( no impurity, no oxidation etc.) 3、Control the use of lubricants. Follow lubricant manufacturer's recommendations for PH, temperature, conductivity and density. 4、Management of Diamond dies: Based on the die drawing wire output and quality of wire, make the corresponding dies maintenance and recutting standard.
