Bimetallic Barrels

All Plasti-Co® bimetallic barrels are manufactured as one-piece units. This can avoid some of many of the problems that can occur with multi-piece designs. Our superior one-piece design eliminates distortion-related problems common with multi-piece designs.

Here’s a look at our bimetallic barrels for your injection molding or extrusion machines:

  • PC-100 Nickel/Boron Bimetallic Lining: The PC-100 nickel-boron base alloy delivers excellent abrasion resistance, very high hardness and a very low friction coefficient that helps prevent screw and check ring galling. This particular liner works well with low to moderately abrasive materials and has a Rockwell C 60-65 hardness range.
  • PC-700 High Abrasion Resistance Tungsten Carbide Bimetallic Lining:The PC-700 utilizes the best wear and corrosion-resistant, high tungsten carbide content alloy with a chromium-boron-nickel alloy matrix. Over 80% of the alloy has tungsten carbides and chromium borides, achieving hardness of Rockwell C70.

With so many different factors influencing the barrels behavior, it’s important to work with the experts who can evaluate your unique application requirements for the best solution and pairing of your application with the correct selection of barrel and screws.

The barrel of a molding machine is one of the most important components, supporting the rotating and/or reciprocating screw and having consistent heat distribution across the entire barrel. The barrel must be well-suited to the demands of the machine and the materials being processed. Plasti-Co® offers a wide range of barrels for extrusion and injection molding machines, as well as repair services & support, utilizing our expert technicians.
