What services we provide
We provide a comprehensive range of PCD (Polycrystalline Diamond) and Tungsten Carbide drawing dies designed for the most demanding industrial wire production. Our PCD dies offer the hardness of natural diamonds combined with the toughness of carbide, making them ideal for long production runs of copper, aluminum, and stainless steel. For larger diameters and specialized shapes, our high-density Tungsten Carbide dies provide the structural integrity needed to withstand extreme pressure while maintaining precise geometric tolerances.
Micron-Level Tolerance
We guarantee hole diameter accuracy within ±0.001mm to ensure your wire stays perfectly on-size.
Superior Surface Finish
Every die is polished to a mirror-like Ra 0.05-0.1 surface roughness to eliminate wire breakage and dust.
Material Integrity
We guarantee 100% virgin raw materials with no recycled scrap, preventing premature cracking or chipping.
Perfect Concentricity
Guaranteed alignment between the die casing and the drawing core for uniform wire reduction.
How We Do It
Sourcing Global Material
We use top-tier PCD blanks (such as Sumitomo or Element Six) and sub-micron grade carbide for maximum wear resistance.
EDM Precision Shaping
We utilize advanced Electrical Discharge Machining (EDM) to carve the initial die geometry with extreme accuracy.
Multi-Stage Ultrasonic Polishing
The die profile is refined through multiple stages of ultrasonic polishing using diamond paste to achieve a flawless internal finish.
Laser Inspection System
Each die is validated by our automated laser measurement system, ensuring the reduction angle and bearing length match your technical drawings exactly.
FAQ
Q: When should I choose PCD over Tungsten Carbide?
A: PCD is recommended for high-speed, long-run production where tool life and surface consistency are priorities. Carbide is more cost-effective for larger wire sizes or short-run specialty batches.
Q: Can you produce square or hexagonal shaped dies?
A: Yes, we specialize in custom-shaped dies including square, rectangular, and hexagonal profiles in both carbide and PCD materials.
Q: What information do I need to provide for a custom quote?
A: Please provide the entry diameter, finish diameter, the material you are drawing, and the specific drawing speed of your machinery.
