TOOL STEEL LINED BARRELS

For all our screw types we are able to apply both gas and Ion Nitration.

NTP also has a variety of tool steel materials available which are used to manufacture barrels.

Tool Steel lined Barrels are high in toughness, Highly abrasion resistant and have hardness of 60-62 HRC with interlocked micro-structures

Our Lining materials are Air-Hardened and Tempered which helps the micro-strucutures to be uniformed.

SPECIFICATIONS:

Available Size: Diameter 50.0 - 200.0MM
Insert Method : Heat & Shrink fit with certain clearance
Support Material : EN-41B (Musco)
Lining Material : D2 , K110 , M2 , S-600

Benefits

  • Increased throughput and product quality through precision fit between the screw and barrel for a longer period of time
  • Improved productivity
  • No degradation or contamination of the process due to no seams trapping polymers (for barrels up to 6100 mm [240″])

Features

  • Optimum resin-tailored feed depth
  • Optimum zone length
  • Optimum metering depth

Applications

  • Highly glass-filled materials
  • Materials with metallic powders or mica fillers
  • Shear-sensitive polymers
  • Undemanding processes
