Super-G High-Speed Extruders
High-Speed Solution with Improved Melt Quality
Processing Technologies International, LLC (PTi), a global manufacturer of high-performance sheet extrusion machinery, has entered the high-speed extruder segment with the launch of its Super-G High-Speed Extruders for the processing of polypropylene (PP) and high-impact polystyrene (HIPS) for the packaging market. The Super-G SGHS3000, which comes in two models and delivers significant performance advantages.
To the manufacturer's product presentation
The new technology offers a high-speed solution that delivers improved melt quality as a result of our Super-G Lobe screw technology and comes with all of PTi's advanced G-Series Configurable roll stand configurations (© PTi)
The Super-G SGHS3000-36D is equipped with a 500 hp motor and runs at a maximum speed of 1000 rpm while the Super-G SGHS3000-42D has a 600 hp motor and runs at a maximum speed of 1200 rpm. Each is capable of faster speeds, however, PTi establishes the maximum rated speed based on an upper motor load threshold of 85 %. For processing of PP, the Super-G SGHS3000-36D has a production output of approximately 3,000 lb/hr. In addition to delivering excellent melt quality, PTi’s high-speed extruders feature carbide-lined barrels and Colmonoy hard-faced feed screws versus case-hardened screws as featured on competitive models.
The Super-G high-speed extruders boast an oversized feed section which promotes higher regrind feed rates (up to +70 %) along with a streamlined feed hopper with support, delivery chute, and tramp metal protection. Other key features include feed screw removal out-the-back of the unit, an easy-cleanout vent chamber, and linear bearing barrel glide support (patent pending). Special air-cooled heater and blower assemblies limit the exterior heater temperature for safety and efficiency purposes (< 110°F) versus competitive models which can be as high as 500°F.
According to the manufacturer, he machine is very energy efficient (i.e.; PP 6-7+ pounds per hour per horsepower) and features a compact footprint of 17.5-ft x 4.5-ft (5.3m x 1.4m) for optimal space utilization. The Super-G High-Speed Extruders are manufactured in the U.S. at PTi headquarters in Aurora, IL.
