Carbide Cold Drawn Polycrystalline Die Description:

Carbide cold drawn polycrystalline die is the core tool in the cold drawing process of metal wire, bar and tube. It is made of high wear-resistant and high-strength tungsten carbide (WC) based tungsten carbide material through advanced powder metallurgy technology and precision machining process. This product has become the first choice for high-efficiency, high-precision cold drawing production due to its extremely high dimensional accuracy, excellent wear resistance, outstanding fatigue resistance and smooth surface finish. Carbide cold drawn polycrystalline mold is widely used in industries such as wire and cable, metal products, precision instruments and automotive parts.

Features of Carbide Cold Drawn Polycrystalline Die:

1. Extraordinary Wear Resistance And Long Life

● Material Advantages: Made of ultra-fine tungsten carbide powder and cobalt (Co) bonding phase sintered under high pressure, it has a dense and uniform structure and extremely high hardness. It can effectively resist the severe friction and wear of the drawn metal material, and its service life is dozens or even hundreds of times that of traditional steel molds.

● Economic Benefits: The extremely long replacement cycle greatly reduces downtime, reduces mold inventory and replacement costs, thereby significantly improving production efficiency and overall economic benefits.

2. Extremely High Dimensional Stability And Processing Accuracy

● Polycrystalline Structure: Tungsten carbide with a polycrystalline structure has an extremely low thermal expansion coefficient and extremely high rigidity. It is not easy to deform under the heat and tension generated during the drawing process. It can always maintain the stability of the die hole size, ensuring the high consistency and interchangeability of the drawn product size.

● Precision Machining: The inner hole working area (entrance area, lubrication area, compression area, sizing zone, exit area) is precision ground and polished, with smooth contour curves and a surface finish that can reach mirror level (Ra < 0.025μm), effectively reducing the pull-out force and ensuring product surface quality.

3. Excellent Surface Finish

● The extremely hard and smooth die hole surface can minimize adhesion to metal materials, reduce scratches and surface defects, and make the surface of the drawn wire and rod smooth and bright without the need for excessive subsequent surface treatment.

4. Excellent Impact Resistance And Fatigue Resistance

High-quality tungsten carbide has both high hardness and good toughness. It can withstand the inevitable vibration and impact loads during the cold drawing process, and effectively prevent early failures such as chipping and cracking.

Application Areas:

● Wire and cable industry: Wire drawing of copper wire, aluminum wire and alloy wire.

● Metal products industry: precision drawing of stainless steel wire, welding wire, steel wire rope, piano wire, galvanized iron wire, etc.

● Precision equipment industry: Forming of various precision alloy bars and tubes.

● Other fields: Drawing of precision components such as automotive piston rods and hydraulic rods.
