Polycrystalline diamond stranding, compacting and bunching dies

Weilly Diamond designs and manufactures Polycrystalline Diamond (PCD) stranding, compacting, and bunching dies engineered for long life, dimensional precision, and process stability. Produced from premium-grade PCD and finished through advanced polishing techniques, these dies offer excellent wear resistance, concentricity, and smooth surface quality, ensuring consistent wire flow during cable manufacturing processes.

Available in custom diameters from 0.3 mm to 25 mm, Weilly’s stranding, compacting and bunching dies are designed to suit a wide range of cable and wire harness configurations. The optimized internal geometry and mirror-polished finish promote even strand compaction and improved conductor roundness, reducing wire deformation and extending die lifespan.

Ideal for power cables, communication lines, automotive wire harnesses, and industrial multi-strand conductors, Weilly’s dies provide the precision and reliability required in continuous, high-volume cable production.
