The efficiency and throughput capabilities of Davis-Standard’s high-speed extrusion technology will be on display during K 2016, which is scheduled from October 19-26 in Dusseldorf, Germany. The company states it is one of only a few manufacturers worldwide to offer a high-speed extruder for demanding processes where rates and energy savings significantly impact profitability. Advantages such as better product quality, less machine volume for reduced changeover time and a wider processing window are just a few reasons high-speed extrusion is a cost-effective option.
“We’ve supplied high-speed technology for a while, but there is still a lot of opportunity for those who seek new ways to boost throughput and performance,” says Steve DeAngelis, Davis-Standard VP of sheet and foam. “The potential for improved processing is especially evident for high-speed sheet, fiber and extrusion coating processes. Our design has demonstrated excellent thermal stability and melt quality at throughput rates up to 1,500 kilograms per hour (3,300 pounds per hour). It has also shown increased performance density for PP and PS extrusion. We look forward to discussing these benefits with customers during the show.”
Davis-Standard’s 75mm, 40:1 extruder offers processing versatility due to a favorable surface-to-volume ratio when compared to conventional extruders. The extruder can be supplied with a direct drive AC motor or permanent magnet synchronous motor configuration. Davis-Standard’s high-speed model offers energy savings of 10 to 15 percent when compared to traditional systems. Additionally, the screw speed and drive unit can be adjusted to accommodate different processing conditions. Davis-Standard has done extensive work on screw designs to further support performance.
