Tungsten carbide , also called cemented carbide , is a composite of tungsten carbide particles and metal cobalt. Tungsten carbide is a non-oxidizing hard alloy that maintains a similar hardness to corundum or gemstones even at very high temperatures . Tungsten carbide has been used as a core for wire drawing dies for more than 100 years and is still widely used.
The nano coated drawing die is made of tungsten carbide die, which is modified and specially pretreated, and then coated with multi-layer micron-nanometer diamond film by ultra-vacuum equipment, which obviously improves the wear resistance of the die core and the service life of the die.

The die is an important part of the drawing process, but it is important to understand that it is part of a chain and that its performance is linked to other parts like the machine, the lubricant, the raw material, etc. So, it is important to make sure that all these elements work together in the best way possible. Nevertheless, even when all the drawing conditions are under control, the drawing process puts wear in the dies; the wire leaves marks on the diamond surface and die maintenance becomes necessary. Problems such as ring wear in the reduction zone, increase of the aperture in the bearing zone and decrease of the surface finish may eventually lead to blank ruptureanddie scrap.
We provides customers with die repair and maintenance service .In strict accordance with the standards of new dies, the used dies are modified in aperture and the inner surface of the blank is reshaped andre-polished , thus significantly prolonging the service life of the dies and reducing the production cost for customers.
