At the MD&M show next month in Anaheim, CA, one of the exhibitors, a manufacturer of plastics extrusion lines, will run one of its new machines. What makes it special? The extruder does not require a gearbox and so works well in clean rooms or other controlled environments.
Made and marketed by American Kuhne Inc. (Ashaway, RI), the new extruder will be running Feb. 8-10 at the MD&M (Medical Design & Manufacturing) West show, processing a thermoplastic elastomer (TPE) tube. Because it does not require a gearbox, the line does not create any contamination (from drive belt dust and gear oil) and so reduces potential contamination in a clean room environment.
This extruder includes a high torque, low-speed synchronous AC motor with integral thrust bearing that directly drives the screw. According to the manufacturer, the combination of the permanent magnet motor and elimination of the gearbox increase the machine's energy efficiency by at least 10%.
American Kuhne will be demonstrating the line at its MD&M stand, #2330a. The company's offerings include extruders sized from 0.5 inch (12.7 mm) through 12 inches (305 mm). The company maintains two medical tubing lab lines capable of multi-lumen and taper tube extrusions for customer trials in its facility in Ashaway, and at its European facility at Kuhne GmbH in St. Augustin, Germany. —MPW Staff
