Typical applications
Aluminum wire, copper wire, stainless steel wire, tire cord and welding wire
PCD dies are selected by blank type, hole range, casing design and recut allowance, then finalized around the drawing process.
Application Range
Typical wire and process applications
PCD dies are selected for long production runs, but service life and finished-wire quality also depend on grain structure, reduction angle, bearing length, back relief, lubrication and the reduction schedule. Correctly matched geometry supports wire roundness, stable sizing and consistent surface finish while reducing unplanned die changes.
Typical applications
- Copper, aluminum and alloy wire drawing
- Steel, stainless steel, tire cord and welding wire production
- Continuous lines where die wear and size stability affect output quality
Selection Guidance
PCD Dies for Multiwire Drawing and Continuous Lines
For continuous or multiwire drawing, compare self-supported and tungsten carbide-supported PCD blanks against wire material, lubrication, machine elongation, pass reduction and target surface finish. Share the start and finish sizes, pass sequence, current die life, wear pattern or size drift so the bore geometry and maintenance plan can be reviewed.
