Tungsten Carbide Extrusion Die

What Is a Tungsten Carbide Extrusion Die?

A tungsten carbide extrusion die is a precision tooling component used to force metal material through a shaped opening to produce bars, tubes, profiles, and wires with consistent cross-sections. Renyuan Mould manufactures high-performance carbide extrusion dies for non-ferrous and ferrous metal extrusion.

These dies must withstand extreme pressure and abrasive wear, making tungsten carbide the preferred material.

Advantages of Carbide Extrusion Dies

Tungsten carbide extrusion dies offer high compressive strength, excellent wear resistance, and long die life. They maintain precise dimensions and polished bearing surfaces over millions of extruded parts, improving product consistency and reducing tooling costs.

The material also resists corrosion from aluminum, copper, and other non-ferrous metals during high-temperature extrusion.

Die Types and Profiles

We produce extrusion dies for solid bars, hollow tubes, wire, and custom profiles. Die openings can be round, hexagonal, fluted, or specially shaped according to customer cross-section drawings. Bearing lengths and entry angles are optimized for smooth material flow.

Grade Selection

Medium-grain carbide grades with balanced wear resistance and toughness are typically used for extrusion dies. Fine-grain grades are used for precision wire and profile extrusion. Coarse-grain grades handle heavy-section extrusion with high impact loads.

Manufacturing Process

Carbide extrusion dies are produced by powder pressing, vacuum sintering, and precision machining. Die openings are formed through grinding, EDM, and lapping, then polished to achieve mirror-like surfaces for optimal material flow and surface finish on extruded products.

Tolerances and Surface Finish

Die opening tolerances of plus or minus 0.005 millimeters are achievable. Bearing surfaces can be lapped to Ra 0.05 or better, ensuring smooth extrusion and excellent surface quality on finished parts.

Applications

Our extrusion dies are used for aluminum, copper, brass, magnesium, and steel extrusion. They serve the construction, automotive, electrical, and consumer goods industries for producing bars, tubes, profiles, and wires.

Custom Die Design

Renyuan Mould provides custom extrusion die design based on customer cross-section drawings, samples, or material specifications. We assist with profile geometry, bearing length, and grade selection to optimize die performance and product quality.

Quality and Delivery

Every die is inspected for dimensions, surface finish, hardness, and visual defects. Dies are protected with anti-rust coating and packed securely. Standard delivery is two to four weeks worldwide.
