PTi introduces new high-speed sheet extruder
SUPER-G HighSPEED SGHS3500-36D
This latest extruder improves system performance in output and flexibility, according to a recent press release.
Advancements in technology and design have brought about a multi-resin capable extruder with higher regrind recovery rates, reduced maintenance costs and increased throughput, all with minimal changes to the physical footprint of the original SUPER-G HighSPEED Extruder. When it comes to process applications, the new HighSPEED SGHS3500-36D Extruder achieves reliable, cost-effective, high-density manufacturing— yielding high production outputs within a small machinery footprint.
President Dana Hanson said: "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. Its purpose will bridge the gap between higher levels of both output and regrind consumption and, according to its namesake, will operate up to 1,000rpm."
To achieve the goals of bridging the gap, specific design changes were necessary. A re-engineered and increased screw diameter from 3" to 3.5" (90mm), a L/D of 36:1, a 600 hp motor and a significantly larger feed opening are the featured characteristics of the SGHS3500-36D.
With a 40 per cent increase in area, the unique feed arrangement permits high regrind recovery rates whilst maintaining consistent output levels throughout the production process. These design changes have proven substantial and are the basis for the SGHS3500-36D's ability to achieve a maximum output capacity of 3,600pph, leading to a 33-38% increase in throughput over PTi's SGHS3000-36D (75mm) extruder.
Increased output numbers can prove further significant to the ‘bottom line’ when considering the flexibility for quick changeovers made possible by the SGHS's multi-resin capabilities of processing HIPS, PP, and PET.
