    Davis-Standard LLC says its SHO extruder offers next-level groove feed performance in a space-saving, energy efficient package.

    Pawcatuck, Conn. — Davis-Standard LLC introduced two new machines – one a groove feed innovation for pipe extruders and the other for a wide range of coating applications.

    In a news release about the launch of the SHO extruder, the company says it achieved outputs up to 20 percent higher than existing groove feed models and improved energy efficiency with help from a DSB brand barrier screw.

    This is especially beneficial for high-viscosity high density polyethylene applications such as pipe extrusion, where lower melt temperatures, reduced power consumption and improved energy efficiency are paramount, according to John Christiano, vice president of technology.

    "Improving energy efficiency equates to tangible savings for your operation while reducing your carbon footprint," Christiano said.

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

    In addition to improved output, the extruder provides output consistency, melt quality and reduced purging/changeover time, the release says.

    "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," Christiano said.

    The other machine introduced is the CHP extruder, which Davis-Standard says is a high-performance option for a range of extrusion coating applications.

    The machine has a smaller footprint and is lighter weight to allow for easier addition to an existing carriage or platform structure. The release says this provides processors with a space-saving replacement or coextrusion addition for increasing outputs and line speed.

    This design addresses profitability factors, such as reduced raw material loss, improved outputs, and greater application development, according to Danis Roy, Davis-Standard vice president of sales for films and flexible packaging.

    "The CHP is built for exceptional performance with improved transition times and significantly higher processing rates than conventional extruders. We're excited about the results we'll see in the field," Roy said.

    The CHP is available in sizes ranging from 2 inches (52 millimeters) to 3.9 inches (100 mm). The release says processors benefit from efficient mixing that delivers low pressure, melt-temperature variability, and output rates up to 80 to100 percent higher than current extruder options.

    Davis-Standard has a CHP extruder at its laboratory in Pawcatuck, Conn., for customers to run trials and validate processing opportunities prior to purchase.
