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.
