AT Series 2-die 2-blow header

The Asahi Sunac 2-die 2-blow AT Series cold headers are the world's best selling machines of their type.

  • 2-die 2-blow machines, Asahi Sunac's 2-die 2-blow AT Series cold headers are more productive because they deliver on completed workpiece for each ram stroke.--No1 Market Share
  • 2-die 2-blow machines, the AT cold header's two dies not only make it possible to form shank voids, but significantly reduce running vibration as well.
  • Designed to provide a highly stable forging action at high speeds, the AT cold headers use positive drive cams to power the cutoff and transfer systems. The result is a quieter running machine with less vibration and improved operating stability at any speed.
  • AT headers can produce an extremely wide range of workpiece types. Eighteen models are available that can produce workpieces from 4mm to 20mm in diameter with various stroke lengths for producing short, medium, or long length blanks.--Forging Examples
