Application Range

Typical wire and process applications

Natural diamond dies provide a hard, smooth working surface for fine and ultrafine wire. Yongyi prepares the bore geometry, bearing and casing around the target size and wire material, then supports the tooling with inspection, repolishing and recutting when required.

Typical applications

Fine copper, alloy and precious metal wire
Fine steel and stainless steel wire
Specialty wire where a smooth surface finish and stable size control are critical
