Brief Introduction

It used high-quality cemented carbide as the core, it has high wear resistance, good polishing performance, small coefficient of friction, high coefficient of thermal conductivity, good corrosion resistance and other features. Tungsten carbide wire drawing die compared with other wire drawing dies, low cost, more economical than other molds, very suitable for drawing large-sized wire.
Diameter range:≥1mm.

Tungsten Carbide Dies Failure Mode Analysis
Circumferential crack at the bottom of the wear ring propagates by splitting the nib in two(also breakage can be in the form of a cone).
Nominal Cause
It usually occurs when a die is left in the machine to long and the stress concentration makes that wear ring became too deep. It is easily noticeable because the crack revolutions in the radial direction.
Possible Solutions:
Most tension failures can be avoided with a good die maintenance program.
FAQ:
Q: What happens if a customer changes the grade for an existing nib pressing tool?
A: Different grades could have different shrink ages. This effect could affect the final nib dimensions.
Q: Is hot casing better than cold casing?
A: The nib after hot casing is under compression not only in the radial but also in the axial direction. This leads to a better stress balance during the drawing process and increases the die life.

Product Advantage

• Good thermal conductivity, small friction coefficient.
• Low cost, used in some wire processing technology with high loss and high hardness.
•The extremely high hardness and wear resistance ensure a long service life of the die.
•Low dies cost.
•Excellent corrosive wear resistance.
•Available in a large range of sizes.

Product Application

•Drawing ferrous and non-ferrous metals
The tungsten carbide wire drawing die has high thermal conductivity, small friction coefficient, and small power loss. It is more economical than natural wire drawing die and polycrystalline wire drawing die when drawing ferrous and non-ferrous metals, and the quality of the drawn product is completely acceptable in terms of quality. Meet customer requirements.

•Drawn steel cord
Steel cord is one of the most difficult products to produce in metal products. The surface is made of high-quality high-carbon steel and the surface is plated with brass, which requires high production technology. And our company's tungsten steel wire drawing die has extremely high wear resistance, excellent polishing coefficient, small friction coefficient, and little damage to the die, which is very suitable for drawing steel cord.

•Suitable for drawing metal wires, tubes and rods
The diameter range of the tungsten steel wire drawing die is very large, with good wear resistance and impact resistance. Therefore, when drawing metal wires, pipes and bars, the damage to the die is small and the drawing efficiency is high.
