PCD Wire Drawing Dies
JCB diamond wire drawing dies come in three main types: single crystal, PCD, and CVD dies. They are highly wear-resistant and last very long. These dies are widely used for drawing high-precision wires in electronics, radar, TV, instruments, aerospace, and more. They also handle common wires like tungsten, molybdenum, stainless steel, cable wires, and various alloy wires.
Key Features
Long Service Life: Homogeneous PCD structure resists microcracks and extends die longevity.
Superior Heat Conductivity: Rapid heat dissipation preserves die integrity and wire quality.
High Impact Toughness: Dense intercrystalline bonds prevent chipping and fracturing under load.
Precision Geometry: Sub-micron CNC grinding and laser trimming ensure low friction and consistent wire dimensions.
