PCD wire drawing die is made of diamond powder under the action of metal catalyst (cobalt), and it is sintered with high pressure and high temperature process.Under the condition of strict process control, diamond micro-crystalline particles formed between health, making it similar to natural diamond high hardness and high thermal conductivity, at the same time, because of the diamond powder for irregular arrangement, make poly-crystalline diamond performance for isotropic, processing without considering its orientation, and has better toughness and wear resistance.

Our company uses different kinds of polycrystalline diamond as the raw material, which is a kind of uniform ultra-fine particles by the high temperature, high pressure crystallization, guaranteeing the out of roundness of wire rod and has high surface finish, drawing long life, in the process of drawing for a long time and it is hard for mould to wear and have flat wire.


Application range
