On March 10, 2017, Processing Technologies International, LLC (PTi), a leading global manufacturer of high-performance sheet extrusion machinery, announced that it has entered the high-speed extruder segment with the launch of its Super-G (R) High-Speed Extruders for the processing of polypropylene (PP) and high-impact polystyrene (HIPS) for the packaging market. The Super-G (R) SGHS3000, which comes in two models, delivers significant performance advantages and overcomes the limitations of competitive products.
   “Our new high-speed extruder technology sets a new industry standard because of its innovative and unique design and performance,” said Dana Hanson, president of PTi. “This technology offers our customer base a high-speed solution that delivers improved melt quality as a result of our Super-G (R) Lobe screw technology and is offered integrated with all of our advanced G-Series (R) Configurable roll stand configurations.”
   The  Super-G (R) SGHS3000-36D is equipped with a 500 hp motor and runs at a maximum speed of 1000 rpm while the Super-G (R) 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 (R) 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 (R) 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.
   The 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 (R) High-Speed Extruders are manufactured in the U.S. at PTi headquarters in Aurora, Ill. A Model SGHS3000-36D will be ready later this spring for demonstrations and customer trials at PTi’s newly constructed Technology Development Center. In order to meet customer service needs, PTi offers a comprehensive offering of technical services including installation support, process engineering, and operator training along with an extensive spare parts stocking program.
