High Precision Tungsten Carbide Tube Drawing Dies for Metal Pipe Production

Tungsten Carbide Tube Drawing Dies Specifically designed for reducing the outer diameter or wall thickness of metal tubes (e.g., copper pipes, stainless steel seamless tubes).

Features: Includes internal mandrels (floating or fixed) and external dies to ensure concentricity and smooth inner/outer surfaces.

Product info

Our tungsten carbide drawing dies are manufactured using 100% virgin premium powder through a low-pressure vacuum sintering process. This ensures a dense internal structure free of porosity.

l High-Precision Bore: The die bore undergoes precision grinding and ultrasonic mirror polishing. The surface roughness reaches Ra 0.05-0.1μm, effectively reducing drawing resistance and ensuring an ultra-smooth finish on the wire surface.

l Superior Wear Resistance: Extreme hardness ensures exceptional dimensional stability during high-speed drawing, significantly extending replacement cycles and reducing downtime costs.

l Scientific Die Geometry: We optimize the angular design of the lubrication zone, reduction zone (compression zone), bearing zone (sizing zone), and exit zone based on the specific material being drawn (e.g., hard steel vs. soft copper) to ensure scientific metal flow.

Main Applications and Fields

u Wire & Cable Industry: Drawing of copper and aluminum core wires for power cables, communication cables, and enameled wires.
