Aurora, Ill.-based Processing Technologies International LLC says its latest extruder developments have resulted in a multi-resin machine with higher regrind recovery rates, reduced maintenance costs, increased throughput and minimal changes to the footprint of the original Super-G highSpeed (SGHS) extruder.
Called the SGHS Model 3500-36D, the extruder features a re-engineered and increased screw diameter from 3 inches to 3 1/2 inches (90 millimeters), a 600 hp motor and a significantly larger feed opening — a 40 percent increase — to handle high regrind recovery rates of up to 70 percent while maintaining consistent output levels. These design changes are the basis for the SGHS3500-36D's ability to achieve a maximum output capacity of 3600 pph, which is a 33-38 percent increase in throughput over PTi's SGHS Model 3000-36D (75mm) extruder.
"We've had such a grand market reception for our SGHS Model 3000 (75mm) over the past three years that we're taking the next steps to expand this offering," PTi President Dana Hanson said in a news release. "Its purpose will bridge the gap between higher levels of both output and regrind consumption and according to its namesake, will operate up to 1000 rpm."
The high-speed extruder uses PTi's patented M-ATEX barrel glide supports to assist in managing thermal expansion and the two-stage SUPER-G lobe screw technology for mixing, melt quality and temperature control. PTi says these features maintain consistent sheet gauge thickness and achieve high clarity for crystalline and semi-crystalline polymers.
While the design of the SGHS3500-36D required an additional 18 inches – an increase of about 8.5 percent — to the overall length of the extruder, PTi says it manages to yield a 20-25 percent increase in manufacturing footprint efficiency and the company still offers the smallest footprint in the category of high speed extruders.
Companies interested in testing their resin and application processes on the SGHS3500 can schedule a trial.
