• Closed extrusion dies are used when more than 30% cross-section reduction is needed
• Carbide material with different hardness

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.
