QC3-43mm

Twin-Screw Extruder with a 43mm Barrel Bore Diameter

Entek, Lebanon, OR/USA, a producer of twin-screw co-rotating extruders and microporous separators for lead-acid and lithium batteries, will introduce an all-new 43mm twin-screw extruder at NPE 2015 in Orlando, FL. According to the company, the new QC3 -43MM provides important benefits to compounders.

QC3 stands for Quick Change, Quick Clean and Quality Control. The Quick Change feature 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: The new extruder frame design deflects dust and keeps machine clean under the hood, and, according to the company, stainless steel and powder-coated surfaces look great today and 10 years from now. An 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. Top-quality components manufactured here give years of top-quality performance.

Increased production rates (33% higher output shaft torque) with a 200HP/1,200rpm motor and an increased screw OD/ID make the new extruder suitable for compounding the most challenging formulations. The SMART controls feature enhanced graphics, recipe library, trending software, and web-based connectivity for remote troubleshooting.

The QC3 -43MM twin-screw extruder features a 43mm barrel bore diameter, which is a new size for Entek machines. “Our research has shown that this size is the most common for general material compounding applications,” said John Effmann, Entek Extruders’ Director of Sales & Marketing. “We will continue to provide the industry with our complete range of machines, which run from 27-133mm sizes. For now, the QC3 -43MM is the only Entek twin-screw extruder with these new features, but we will phase in these design changes to our other machines as well.”
