Natural diamond dies for fine wire drawing

Weilly Diamond manufactures Natural Diamond dies (ND) using high-grade, single-crystal natural diamonds with {111} crystal orientation for superior hardness and dimensional stability. Designed for fine and ultra-fine wire drawing, these dies ensure exceptional wear resistance, low friction, and extended service life.

Produced with advanced machining and polishing technology, Weilly’s ND dies feature mirror-finished bores and tight dimensional tolerances for wire diameters from 0.015 mm to 2.5 mm. They guarantee smooth wire flow, reduced drawing resistance, and consistent quality over long production runs.

Applications include copper, aluminum, gold, silver, stainless steel, brass and precision alloys wires. Weilly’s ND dies are widely used in the electronics, medical, and high-precision metalworking sectors where accuracy and surface quality are critical.
