Products Overview

QC3 43mm Extruder
  • Designed with Customer Input to Provide What Compounders Need and Want:
  • Quick Change, Quick Clean, and Quality Control
  • Quick Change: Allows for fast, easy screw-set changeovers. New self-alignment feature takes the worry out of installing the screws into couplings, and new design allows screws to only be installed one way – the correct way. Guards come off quickly, and go back on the same way. All necessary tools for changeover and maintenance are mounted at point-of-use on the extruder.
  • Quick Clean: New extruder frame design deflects dust and keeps machine clean under the hood, and Stainless Steel and powder-coated surfaces look great today and 10 years from now. Optional device allows for fast, easy barrel cleaning.
  • Quality Control: All QC3™ twin-screw extruders are engineered and built at ENTEK’s headquarters in Lebanon, Oregon U.S.A. Top-quality components manufactured here in our shop give years of top-quality performance.
  • Better Compounding: Increased production rates (33% higher output shaft torque) with 200HP/1,200rpm motor and increased screw OD/ID for compounding the most challenging formulations.
  • Ease of Use: SMART controls feature enhanced graphics, recipe library, trending software, and web-based connectivity for remote troubleshooting.
