Davis-Standard to Showcase Advantages of Direct Drive Technology at NPE
Pawcatuck, Conn. – To demonstrate the superior performance of direct drive extrusion, Davis-Standard will feature a 3 1/2 (90mm) direct drive extruder at NPE. Based on a recent series of tests conducted at Davis-Standard’s Technical Center in Pawcatuck, Conn., direct drive technology has shown significant advantages in energy consumption, sound level, and output consistency over AC and DC extruder models. Davis-Standard’s engineers will have the information available to NPE visitors at booth W6144.
“We continue to discover ways to manufacture equipment that is environmentally sustainable and supports the profitability of our customers. Our experiment with the direct drive technology is an example of that innovation,” said John Christiano, Davis-Standard’s Vice President of Technology. “Our side-by-side comparison of direct drive versus AC and DC drive technology revealed consistently quieter operation that reduced noise by as much as 70 percent. Screw design optimization in combination with these extruder design enhancements can lead to up to a 15 percent further improvement in energy efficiency.”
Christiano believes there are several factors that contribute to the improved performance of the direct drive extruder model. The direct drive operates on a permanent magnet synchronous motor, which does not require a mechanical gear reducer to multiply torque to rotate the screw. This coupled with an energy efficient screw design enables the extruder to process a greater variety of resins with consistent quality and outputs. An innovative heating/cooling system, narrow footprint, and low-maintenance design further result in operating cost reductions and energy efficiency. Davis-Standard’s direct drive technology is available for processes in several application areas in sizes up to 4 ½ inches (114 mm). It can be customized as needed.
