Parts in the Plastic Injection Molding Industry:

  • Plastic  Injection Moulds
  • Screws
  • Barrels
  • Nozzle tips and nozzle bodies
  • Side-action cores and cavity inserts
  • Ejector Pins and sleeves
  • Slides and lifters
  • Bushings and guide pillars

Requirements for the parts:

  • For high Wear resistance
  • For high Fatigue strength
  • For Reduced friction and adhesion
  • For Corrosion resistance

Ion Nitriding Solutions:

  • Significantly increasing the surface hardness, wear (abrasive and adhesive) resistance and fatigue life of the tools, improving their lifespan and performance.

  • Reducing the friction coefficient  and the adhesion of the plastic material to the tools. Nitriding will also lower the friction for bushings and guide pillars.
  • Increasing the corrosion resistance which is needed for certain additives and processing conditions.

 

Improving these parameters will save from downtime and maintenance costs.

Steel Grades Used:
