The cemented carbide pressure die consists of two parts,a steel sleeve and a tungsten steel core.The tungsten carbide mold core can withstand 2800℃ high temperature.
When the tungsten steel core is worn,it can quickly replace the new products with high hardness,good thermal conductivity and small friction coefficient.
It has low cost and can be used in some wire rod processes with high loss and high hardness.
Wire drawing is done by passing the metal wire through the hole of the Wire Drawing Die, and applying a pulling force to the wire at the exit side of the die. The wire is contracted and squeezed in the die cavity and gradually becomes thinner, and its speed increases near the exit of the die hole. Since the volume of the wire is constant, the decrease in cross section makes it stretched. In the center, there is a hole of a certain shape, such as round, square, octagonal or other special shapes. When the metal is pulled through the die hole, the size becomes smaller and even the shape changes.
The best material depends on the wire you draw and the quantity you draw. Contact us to help you choose the most economical solution and reduce the total cost of ownership of your drawing dies.

Tungsten carbide,also known as cemented carbide,is composed of tungsten carbide particles and cobalt.Tungsten carbide is a kind of non oxidizing cemented carbide,which can maintain the hardness similar to corundum or gem even at high temperature.
Tungsten carbide has been used as the core of wire drawing die for more than 100 years.Now it is still widely used with low cost.It is used in some wire rod processing technology with high loss and high hardness,and even wear when used.
Tungsten steel cemented carbide die is an economical choice for the iron and steel industry,as well as the application in non-ferrous metal industry,such as stranded wire and drawing of large-diameter cable.It has been used in wire rod industry for many years.
With the free arrangement of diamond crystals,the wire rod can still keep good roundness even under the condition of severe wear of die,and the size of blank can be guaranteed,and the expected maximum reaming size can be obtained.It can be used in all wet drawing and dry drawing processes.It is mainly used in larger size, more demanding wear requirements,but less important surface finish.
