Davis-Standard launches SHO extruder

Davis-Standard, based in Pawcatuck, Connecticut, has introduced the latest in its groove feed innovation with the launch of its SHO (super high output) extruder.

According to a news release from Davis-Standard, the SHO is equipped to save space while offering outputs up to 20 percent higher than existing groove feed models and is engineered with an optimized feed section and high-performance, energy-efficient DSB barrier screw. The company says this is especially beneficial for high-viscosity, high-density polyethylene (HDPE) applications like pipe extrusion, where lower melt temperatures, reduced power consumption and improved energy efficiency are paramount.

“Improving energy efficiency equates to tangible savings for your operation while reducing your carbon footprint,” says John Christiano, vice president of technology for Davis-Standard. “The SHO builds upon our existing groove feed technology with a more streamlined, compact footprint and even greater performance in terms of output and energy savings.”

The SHO features Davis-Standard’s next-generation gearcase, which the company says optimizes valuable production space along with a streamlined hopper, low-profile power panel, rugged base and all components fully enclosed.

Davis-Standard says the advantages of the SHO include improvements in output, output consistency, melt quality, reduced purging/changeover time and energy efficiency.

Size ranges for the SHO range from 2 to 6 inches (50 to 150 millimeters) with a length to diameter ratio of 42:1.
