Combination dies

  • Combined rolling dies for complex parts, e.g.
    – Different threads
    – Thread and knurl
    – Thread and forming area
  • As a rule, 2 or 3 different types of threads or shapes are rolled
  • If the pre-roll size is the same, the options can be rolled directly over one another
  • For different pre-rolling dimensions, the options are rolled one after the other
  • Threads can also be provided with tips, grooves or beads
  • The advantage of such rolling dies is that the parts are finished in one operation
