Six-piece combination die

* 6-segment construction – each segment replaceable individually, reducing total die cost by up to 60% compared to solid dies. * Precision-ground mating surfaces – ensure concentricity and alignment within ±0.005 mm, guaranteeing consistent part geometry. * High-grade powder metallurgy steel + PVD coating (TiAlN/CrN) – exceptional wear and impact resistance for stainless/alloy steels. * Optimized split-line design – relieves hoop stress, prevents radial cracking under high forming loads (up to 180 t). * Quick-change capability – segments can be swapped without removing die holder, slashing downtime by 40-50%. * Customizable segment profiles – adaptable to hexagonal, flange, spline, or other special head shapes. * Proven at multi-station headers up to 180 spm – stable performance, scrap rate <0.4% over millions of cycles. * Cavity surface finish Ra ? 0.1 µm – reduces friction, ensures smooth part ejection and bright surface quality. * Optional DLC coating – boosts segment life 2-3× under highly abrasive conditions (e.g., high-silicon steels). * 100% segment-by-segment inspection – each piece hardness-tested (HRC 58-62) and dimensionally verified for full interchangeability.
