Tungsten Steel Mold

What Is a Tungsten Steel Mold?

A tungsten steel mold is a precision forming die made from cemented tungsten steel, used in stamping, deep drawing, extrusion, and metal forming processes. Renyuan Mould manufactures high-quality tungsten steel molds designed for long production life and consistent part accuracy.

Tungsten steel molds are preferred over conventional steel molds in high-volume production because they resist wear, maintain polished surfaces, and hold tight tolerances over millions of cycles.

Key Advantages

Tungsten steel molds offer hardness up to 90 HRA, excellent compressive strength, and outstanding wear resistance. They deliver superior surface finish on molded parts, reduce tool maintenance, and lower the cost per part in mass production.

The material is also dimensionally stable at elevated temperatures and resistant to corrosion from stainless steel and other alloys.

Mold Types

We produce stamping dies, deep drawing molds, extrusion dies, cold heading molds, wire drawing dies, and custom forming molds. Each mold is engineered to match the customer's part geometry and production process.

Mold cavities can be machined with complex profiles, radii, and stepped features.

Material Grades

Fine-grain grades are used for precision drawing and polishing applications. Medium-grain grades balance wear resistance and toughness for general forming. Coarse-grain grades handle heavy impact and high-pressure operations.

Nickel-bonded grades are available for corrosion-resistant requirements.

Manufacturing Process

Tungsten steel molds are produced by powder pressing, vacuum sintering, and precision machining. Cavities are formed through EDM, grinding, and lapping, then polished to achieve the required surface finish.

Each mold component is inspected for dimensional accuracy, hardness, and surface quality before shipment.

Tolerances and Finish

Mold dimensions can be held to plus or minus 0.005 millimeters. Cavity surfaces can be polished to Ra 0.05 or better, ensuring smooth material flow and excellent part finish.

Applications

Our molds serve automotive manufacturing, kitchenware production, metal packaging, fastener making, wire and cable production, and aerospace component fabrication.

Custom Mold Design

Renyuan Mould provides custom mold design based on customer drawings, samples, or part specifications. We assist with cavity geometry, draft angles, and grade selection to optimize mold performance.

Quality and Delivery

Every mold is hardness tested, dimensionally inspected, and visually checked. Molds are coated with anti-rust oil and packed in export-grade cases. Standard lead time is two to four weeks worldwide.
