The superhard CVD diamond coating completely changes the service life of the die. CVD diamond coating drawing die is based on tungsten steel die. Multilayer micron-nano-diamond film was coated by super-vacuum equipment. After polishing and inlaying, it is finished.
After decades of development, many new drawing die materials have appeared. Wire drawing die can be divided into alloy steel die, hard alloy die, natural diamond die, polycrystalline diamond die, CVD diamond die and ceramic die. The development of new material greatly enriches the application range of drawing die and improves the service life of drawing die.
Application of CVD diamond coating drawing die
Suitable for all kinds of gas protection wire, high carbon steel wire, medium and low carbon steel wire, stainless steel wire, copper and aluminum wire and all kinds of special-shaped pipe, wire drawing, no material selection.
