Henan Mainuo Industry Co.,Ltd is a professional manufacturer of tungsten carbide extrusion dies, delivering high-precision, wear-resistant, and long-lasting molds for cable sheath, copper and aluminum rod, plastic profiles, and rubber products extrusion. With years of expertise in hard alloy die manufacturing, Mainuo provides custom solutions to meet the unique production requirements of clients worldwide.

1. Material Advantage – Premium Tungsten Carbide

Mainuo uses high-strength, high-hardness, and wear-resistant tungsten carbide (WC-Co grade), combined with precise formulation and sintering processes. This ensures that our dies maintain dimensional stability and smooth surface finish even under long-term, high-pressure, and high-friction extrusion conditions. Compared with conventional steel dies, tungsten carbide dies offer significantly longer service life and superior product consistency.

2. Precision Manufacturing – Accurate Profiles & Smooth Surfaces

Equipped with advanced CNC grinding machines, wire EDM, and mirror polishing technology, Mainuo can achieve micron-level accuracy in die profiles and ensure mirror-like surface quality inside the working bore. This reduces extrusion resistance, minimizes surface defects, and improves overall production efficiency.

3. Wide Range of Applications

Mainuo tungsten carbide extrusion dies are widely used in:

• Cable sheath extrusion

• Copper and aluminum rod extrusion

• Plastic pipes and profile extrusion

• Rubber sealing strips and automotive parts extrusion

• Powder metallurgy forming

Whether it’s round, square, or complex-shaped profiles, or custom flow channel designs, Mainuo can manufacture dies tailored to your exact requirements.

4. Process Optimization – Designed for Your Materials

Our engineering team understands material flow characteristics in extrusion processes. We can optimize die flow channels, compression ratios, and entry angles according to your material type and production parameters, reducing stress concentration, preventing burrs or deformation, and extending die service life.
