Tungsten carbide cold forging die fastener for Extrusion dies
Henghui’s extrusion dies, Different carbide grades in order to
improve tool performance. Extrusion dies for easy removal and
replacement of it using the same casing.
Accurate concentricity.
This is one of the most important parameters. It guarantees that
the wire will be perfectly centered within the insulation material.
This tight tolerance (0.0025mm / .0001”) is one of the keys in the
quality of our tools.
Marking area
High definition laser marking area with diameter and other
important customer details (upon client request).
Henghui has developed its own state-of-the-art technology in order
to improve tools’ lifespan whilst keeping costs down.
This die design technology allows the use of interchangeable
carbide die on the working area. On extrusion dies, a well-polished
surface is essential,the polishing is done before can extending the
tool’s lifespan.
We will suggest:
The selection of cemented carbide materials.
PVD, different coatings to be applied depending on the extruded
material.
Mature polishing technology
Cemented carbide die is one of the steel dies. It is made of alloy
materials with high strength and hardness, corrosion resistance,
wear resistance and high temperature resistance, which is far
longer than the service life of ordinary steel dies. It is a
popular die in modern machinery industry. The common ones are cold
heading die, drawing die, cold punching die, hexagon die, spiral
die, etc. Its characteristics are as follows:
1) the guiding mechanism of the die adopts the four guide pillar
ball mold base, and the stability, reliability and accuracy of the
guiding mechanism are very high.
2) use T7 as the raw material of the hardened base plate to avoid
the crushing of the cemented carbide die during stamping.
3) most of the formwork bases are made of 45 steel, hrc38-420,
which is thicker than the general steel formwork and increases the
rigidity.
4) at the die handle, in order to prevent the impact of the
precision of the press on the stamping process of the carbide die,
the floating die handle structure should be adopted as far as
possible.
5) the clearance of the concave convex die is larger than that of
the steel die.
6) in order to prevent the impact on the die during stamping, the
fixed discharge plate structure is adopted, and the height h of the
step is one thick material different from the thickness h of the
guide plate.
