Machine builders at NPE2018 are meeting the need for speed. Plus, the latest Super-G HighSPEED Extruders from Processing Technologies International (Booth W6744) have a significantly reduced footprint, resulting in the highest extrusion output/square foot in the industry, the company claims. This compactness is made possible by introducing an optional tuck-under motor on these models, which are used for processing PP and HIPS for packaging. Several machines have already been installed in the U.S.

Process Technologies International's Super-G SGHS3000-36D model on display features a vertical U-configuration and tuck-under motor to reduce the machine's footprint by more than 33 percent to 12 feet, 8 in., versus 17 ft., 7 in. for the original model. The Super-G SGHS3000-42D model is also offered with the tuck-under option and shows a comparable footprint reduction and similar output gains.

The Super-G SGHS3000-36D has a 500-hp motor and runs at a maximum speed of 1,000 rpm, while the Super-G SGHS3000-42D has a 600-horsepower motor and runs at up to 1,200 rpm. For processing PP, the Super-G SGHS3000-36D has a production output of approximately 3,000 lbs/hr.
