Tungsten carbide drawing dies for high-quality carbide core, with high hardness, good thermal conductivity, low coefficient of friction. Carbide drawing dies making simple, corrosion, impact resistance, low price is a significant feature of this product is suitable for ferrous metals, large size wire drawing, and drawing disadvantaged occasions.

Tungsten carbide drawing dies, core processing and loading process mold inserts sets of points should be noted; mainly manufactured in four steps:1.A blank mold processing; 2.Installed inlay interference; 3.Drawing die die sets processing; 4.Replace the inlay craft.
Tungsten carbide drawing dies cores during sintering shrinkage will produce different batches because ingredients, pressing and sintering processes are different, there are large differences in the amount of shrinkage; die blanks all parts vary the amount of shrinkage, often form a "saddle" or "bell" shape. Dimensions fluctuations die blanks, although in line with standard die blanks, but far more than the mold inserts suit the requirements of interference caused when loading inserts core prestressed bear serious inequality, mold life greatly reduced, and therefore, must die blanks were cylindrical grinding, grinding machine using a special need in the fixtures, diamond grinding wheel.
