Our precision-engineered cut-off dies are critical terminal components for high-speed roll forming lines. Designed for both static (stop-and-cut) and flying (non-stop) applications, these dies ensure clean, burr-free cuts at high cyclic rates.
Manufactured from premium SKD11 (D2) or Cr12MoV tool steel, the blades undergo vacuum heat treatment to achieve a hardness of HRC 58–62. This ensures exceptional wear resistance and edge retention when processing high-trength materials like AHSS, Stainless Steel, and Coated Steels. The cutting clearance is precisely ground to match your specific material gauge, guaranteeing perpendicular cuts and extending tool life.
