Multi-station heavy reducing die

* High-strength powder metallurgy steel + AlTiN PVD coating – withstands extreme extrusion pressures (up to 2,500 MPa) and severe abrasive wear on high-strength steels. * Optimized reducing cone angle & bearing length – enables reduction ratios up to 40% in a single station while preventing material folding or cracking. * Precision-ground tapered cavity (Ra ? 0.06 µm) – ensures smooth metal flow, reduces friction heat, and eliminates galling on the reduced rod surface. * Multi-station compatibility – designed for sequential forming; can be placed after upsetting or before threading, perfectly synced with header timing. * Special venting grooves and relief angles – minimize back pressure and allow easy part release, preventing seizure even at 200+ strokes/min. * Tight diameter tolerance (±0.02 mm) – guarantees consistent rod diameters across millions of pieces, eliminating secondary grinding. * Superior toughness (HRC 56–60) – balances hardness with fracture resistance, avoiding chipping under heavy impact and eccentric loading. * Proven at multi-station cold headers (up to 6 stations) – stable performance with scrap rate <0.5% in high-volume fastener production. * Optional DLC or duplex coating – extends die life 2-4× when reducing highly abrasive materials (e.g., alloy steels with high silicon). * 100% dimensional and ultrasonic inspection – ensures zero internal defects and full interchangeability across different header makes.
