Component Materials
Barrels, liners, etc....   Screws, end caps, tip assemblies, etc...
  • Standard Bimetallic -
    Injection and extrusion applications requiring superior general purpose wear resistance.

  • High Wear Carbide Bimetallic - Multi-application use. Superior general purpose wear and corrosion resistant.

  • Corrosion Resistant Carbide Bimetallic - High wear and corrosion applications (Metallic and nonmetallic fillers, etc.)

  • D-2 Steel - Excellent general purpose use. Not to be used with corrosive or abrasive materials.

  • 10V Material or Equivalent- Superior tool steel. Excellent wear resistance, maximum hardness capacities.
  • 4140 Pre-Heat Treated

  • D-2 Tool Steel

  • 9-V Tool Steel Material
    or Equivalent

  • 10-V Tool Steel Material
    or Equivalent

  • 420-V Tool Steel Material
    or Equivalent

  • CRU-Wear Steel

  • 17-4 PH Stainless Steel

  • Nitralloy 135m-nitrided

  • Hastelloy C
Remanufactures & Rebuilds
  • Barrels (Quote Request Form)
    We remanufacture barrels as a cost effective solution to new purchasing. We have the capability to reline 120" from one end up to 180" on a full length sleeve. Available materials include both the bimetallic liners and tool steel liners from general purpose applications (STD bimetallic & D-2) to more corrosion resistant alloys, to the most abrasion and corrosion resistant liners available today (tungsten carbide & 10-V).
    We also maintain a large number of barrel cores in our inventory so it may be possible to have a resleeve done while the customer continues to run his operation, thus eliminating unnecessary and costly down time. Where downsizing or upsizing is required call us to discuss a quote.

  • Honing
    Hones are available to not only remove wearmarks or polish barrels but hone barrels oversize and retrofit screws. Back to top.

  • Feedthroats
    Because of the extensive work involved in manufacturing & fabricating new extruder feedthroats, remanufacturing them has become one of our specialties.
    Alloy bronze bushings are manufactured new and seals replaced as needed. Water jackets are pressure tested for coolant flow and can be acid flushed. Finally feedthroats are inspected for concentricity and checked for proper alignment of feedscrew. Back to top.


  • General repair services
    Barrels can be modified in addition to rebuilding, whether it be plugging or relocating a vent, sort pressure transducer hole, or to repair a pressure sleeve. Back to top.

  • ScrewsWe service all types of screws. (Mixing screws & injection screws for example.)
    We can grind, straighten, weld, and repair hard surface flights with alloys applicable to your specific processing that include both the stellite and colmonoy lines.

New Barrels & Screws
  • Barrels (Quote Request Form)
    Barrels can be manufactured with any type of liner material to ensure the best alloy is selected for your processing requirements, whether it be a mild polypropylene or a more complex engineered glass filled resin. Back to top.

  • ScrewsWe service all types of screws. (Mixing screws & injection screws for example.)
    Depending on your intended application, we can place a broad range of products (profiles, geometry's, and materials) at your disposal. We offer 4140 HT, Nitralloy, and various tool steels, hastalloy, and inconel. Stainless and plating processes of chrome, nickel, and titanium are offered along with the nitriding process. In addition to a single flighted general purpose screw, we also manufacture barrier screws, and mixing screws, designed to meet your processing requirements. Back to top.

  • Tip assemblies
    More offers a wide range of 3 and 4 piece Tip assemblies, to accommodate your processing needs, available are materials such as 4140, H13, D-2,
    9V Material, M4 stainless tool steels etc. Back to top.


  • Nozzle adapters and End caps
    We offer nozzle adapters manufactured from materials that encompass 4140, nitralloy tool steels, stainless alloys to whatever material necessary to meet your particular needs. Back to top.
