PTi Launches High-Speed Extruders for PP & HIPS Processing

Published on 2017-03-23. Author : SpecialChem

AURORA, Ill. -- Processing Technologies International, LLC (PTi) has entered into 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, delivers significant performance advantages and overcomes the limitations of competitive products.

New Industry Standards

Dana Hanson, president of PTi, said:
“Our new high-speed extruder technology sets a new industry standard because of its innovative and unique design and performance. This technology offers our customer base a high-speed solution that delivers improved melt quality as a result of our Super-G® Lobe screw technology and is offered integrated with all of our advanced G-Series® Configurable roll stand configurations.”

Super-G® High-Speed Extruders

  • 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.

Key Features

  • 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.

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® High-Speed Extruders are manufactured in the U.S. at PTi headquarters in Aurora, Ill.
