Precision: 4.1 Die core: Rough drawing (Φ2.2mm-Φ5.5mm): -0.02mm-+0.01mm (the last one is ±0.01mm) Fine drawing (Φ0.8mm-Φ2.2mm): ±0.01mm 4.2 Die case: -0.05mm 4.3 Roundness error: ≤0.005 4.4 Compression angle: Φ1.2mm or less: 10°±2° Φ1.2mm-Φ2.0mm: 12°±2° Φ2.0mm-Φ5.0mm: 14°±2° PCD dies are ideal for long production runs and for drawing abrasive wire materials as they outlast TC, SSCD and ND dies. Polycrystalline diamond dies are available in various grain sizes, both in supported and unsupported configurations. PCD dies provide uniform hardness and extended wear resistance in all directions. Polycrystalline diamond wire drawing die is the longest die life of all materials,which can provide the highest production efficiency and reduce downtime.It is suitable for all applications from large drawing to ultra-fine drawing,with predictable wire surface quality.
