Key Application Areas of Special Shaped Wire Drawing Dies

Electronics and Electrical Industry
Used for manufacturing stainless steel strips (thickness 0.05-0.2mm) for smartphone bezels and tin-plated copper stranded wires (complex cross-sectional shapes) for new energy vehicle high-voltage wire harnesses.
In the processing of 5G base station filter cavity, special-shaped molds can achieve a wall thickness tolerance control of ±0.01mm for rectangular tubes.
Aerospace Field
When drawing TC4 titanium alloy tubes, using PCD dies with ultrasonic vibration assisted technology can reduce the surface roughness from Ra0.8μm to Ra0.2μm.
In the processing of rocket engine combustion chamber cooling channels, the manufacturing of tubes with irregular cross-sections (such as those with helical grooves) relies on high-precision molds.
Medical Device Manufacturing
In the processing of nickel-titanium alloy wires (diameter 0.1-0.3mm) for vascular stents, the mold requires a nano-level surface finish to avoid scratches that could cause the material's shape memory effect to fail.
In the production of porous titanium alloy rods for orthopedic implants, special-shaped molds can achieve the forming of complex structures with a porosity of 40%-60%.
