Entek makes innovation the focus of NPE presence
Twin-screw extruder group Entek discussed technology and corporate develop- ments at its NPE 2024 stand. At previous NPE shows, the group has made one of its extrusion lines the centre- piece of the stand, but it took a different approach this year. Linda Campbell, Vice-
President of Sales, said Entek had so many innova- tions following the six-year gap since NPE 2018 that it decided to focus on all these developments, without a spotlight on one extruder. That said, the group provided updates on its new high output HT 162 twin-screw extruder, which is currently in production and scheduled for shipment in the first quarter of 2025. The HT 162 twin-screw is
the largest machine Entek has ever built. It has maxi- mum power of 4,200 hp and a maximum screw speed of 600 rpm. Rated production capacity goes up to 30,000 lb/h for HDPE, LDPE and PP compounding, as well as for PS, SAN and ABS com- pounding. Polyamide compounding can run at up to 23,600 lb/h maximum. The HT line was launched in 2020 with the introduction
18
of the HT 72 machine. The product expansion, in addition to the HT 162, includes the newest machine, the HT 92, which is in development.
Entek displayed a variety
of other new twin-screw machinery technologies, including: vent flow sensor technology, mounted on a 103 mm twin-screw extruder barrel; VFT twin-screw machinery compounding technology for increased output and improved product quality; a 37mm QC3 stuffer, with mounting arm and 4 x 43 mm twin- screw extruder barrels (to show reach/flexibility) as well as ease of switching between vacuum stuffer and side feeder; and Entek’s twin-screw extruder machin- ery controls. In early 2023, Entek launched a new business unit, Entek Wear Parts Division, and opened a facility in Nevada for items such as screws and barrels. Whereas Entek’s work has previously focused mainly on replacement wear parts for its own extruders, the new facility is manufacturing and selling replacement parts for all brands of twin-screw extruders.
COMPOUNDING WORLD | June 2024 There has been an
increase in demand for barrels and screws, and so on, said Tammy Straw, Entek Wear Parts Division Director, explaining the reason for the group’s investment in a new facility. As for the market for non-Entek wear parts, she said: “We are targeting that aggressively.” Since the launch of the new division in February 2023, the company has increased its offerings, added manufacturing shifts, stocked inventory and reduced delivery times. At NPE, replacement
wear parts displays includ- ed: screw layout program 2.0, with new features added since its 2018 launch; 162 mm screws; 133 mm screw set on shafts; 27mm screw set on shafts. After cost and efficiency
programmes that followed Entek’s acquisition of Adaptive Engineering and Fabrication (AEF) in 2022, the focus is now on exploiting opportunities. Rick Buschini, VP Material Handling Sales, said the company is selling turnkey systems. Material handling displays at NPE included a filter receiver and a vacuum loader. �

Additives group Songwon launched a phosphite antioxidant and a UV absorber at the NPE show. Designed for enhanced
hydrolytic stability, SONG- NOX 9228 is a secondary diphosphite-based antioxidant that Songwon says overcomes the limitations of conventional phosphite or phosphonite antioxidants by enhancing the resistance of polyole- fins to oxidative corrosion, especially at high process- ing temperatures. Robert Seeley, Senior Sales Manager for Polymer Stabilisers at Songwon in the Americas, said at NPE that the new grade “gives us more options”, adding to the group’s large portfolio of antioxidants. SONGNOX 9228
blends well with primary antioxidants and other stabilisers, says the company. As a modified version with a small fraction of tri-isopropanol amine, SONGNOX 9228T brings these performance features to Songwon’s solid phosphites. Also on show at NPE was SONGSORB 1164, one of the latest additions to the group’s UVA offering and a complement to its triazine-based UV absorb- ers for polymers portfolio. It was specially developed to maximise the UV stability of polyolefins intended for use in food-contact packaging applications. �
