39 Extrusion International 6/2021 Davis-Standard, LLC www.davis-standard.com SHO (Super High Output) Offers Next Level Groove Feed Performance „ Davis-Standard introduced the latest in the company’s groove feed innovation with the launch of its SHO extruder. Equipped to save space while offering outputs up to 20 percent higher than existing groove feed models, the SHO is engineeredwith an optimized feed sec- tion and high-performance, energy-ef fi cient DSB® barrier screw. This is especially bene fi - cial for high-viscosity HDPE applications such as pipe extrusion, where lower melt tempera- tures, reduced power consumption and im- proved energy ef fi ciency are paramount. “Improving energy ef fi ciency equates to tan- gible savings for your operation while reduc- ing your carbon footprint,” said John Chris- tiano, VP Technology. Groove feed extrusion technology contributes to improving your bottom line while providing uncompromising melt quality. “The SHO builds upon our existing groove feed technology with a more streamlined, compact footprint and even great- er performance in terms of output and energy savings.” The SHO features Davis-Standard’s next-generation gearcase to optimize valuable production space along with a stream- lined hopper, low-pro fi le power panel, rugged base, and all components fully enclosed. Advantages include improve- ments in output, output consistency, melt quality, reduced purging/changeover time, and energy ef fi ciency. It is avail- able in sizes ranging from 2 to 6 inches (50 to 150mm) with an L/D of 42:1. Compact CHP Extruder Delivers Big Performance In addition, Davis-Standard is pleased to introduce a new compact extruder designed for extrusion coating applica- tions – the CHP. The machine’s sleek design offers a smaller footprint and lighter weight to allow for easier addition to an existing carriage or platform structure. This provides pro- cessors with a space-saving replacement or coextrusion addi- tion for increasing outputs and line speed. “This design addresses pro fi tability factors such as reduced raw material loss, improved outputs, and greater applica- tion development,” said Danis Roy, Davis-Standard Vice President – Sales Films & Flexible Packaging. “The CHP is built for exceptional performance with improved transition times and signi fi cantly higher processing rates than conventional extruders. We’re excited about the results we’ll see in the fi eld.” The CHP is available in sizes ranging from 2 inches (52mm) to 100mm. Processors benefit from efficient mixing that delivers low pressure and melt temperature variability and output rates up to 80 to100 percent higher than current extruder options. In addition, a reduced residence time of 3:1 with a faster purge between resins and colors sup- ports quick changeovers minimizing raw material loss for bottom-line impact. Davis-Standard has a CHP extruder at its laboratory facility in Pawcatuck, Conn., for customers to run trials and validate processing opportunities prior to purchase. The new CHP extruder is a space-saving, high-performance option for a range of extrusion coating applications Davis-Standard’s SHO extruder offers next level groove feed performance in a space-saving, energy ef fi cient package
