FeedScrew Rebuilding

TIR can rebuild your feedscrew back to OEM specification using:

  • Colmonoy #83 tungsten carbide hard-surfacing for greater wear resistance
  • Colmonoy #56 for standard processing and industrial hard chrome to protect the sides of the flights and the root diameter of the feedscrew
  • Industrial hard chrome to protect the root diameter and sides of the feedscrew flight from normal wear and corrosive conditions
  • Encapsulation of the root diameter and sides of the feedscrew flight with N-50 or tungsten carbide for high wear processing

TIR feedscrews can be designed to optimize your extrusion or injection molding process.  From blown film to sheet extrusion, TIR can design and manufacture a custom feedscrew that will result in greater productivity for you.
