Davis-Standard to exhibit HPE Extruder at Chinaplas
Davis-Standard is looking forward to a productive Chinaplas in Guangzhou, May 16-19, (Hall 9.2, Stand J41). As an example of its extrusion technology, Davis-Standard will exhibit an HPE-H extruder for medical tubing applications.
The energy-efficient HPE-H is compact in design, available for a fast delivery, easy to maintain and one of the company’s most widely used models. It is available in 20mm (3/4-inch), 25mm (1-inch), 30mm (1 ¼-inch), 40mm (1 ½-inch) and 45mm (1 ¾-inch) sizes for processing versatility.
Davis-Standard continues to see a strong demand throughout Asia for feedscrews, control systems, medical tubing technology, and its dsX product line for cast film, blown film and packaging applications. Davis-Standard’s regional presence has continued to grow since opening Davis-Standard (Suzhou) Plastics Packaging Machinery in 2012. This facility is Davis-Standard’s manufacturing base in China and houses an R&D laboratory for process development and trials.
“We’ve experienced growth across all platforms in China, but the medical tubing sector has been especially strong for us,” said Sekaran Murugaiah, Davis-Standard vice president of business development, Asia. “Customers appreciate our regional presence and the availability of the medical tubing laboratory in Suzhou to test new resins and processes. These R&D capabilities have been key in ensuring customers in the region are equipped to address market demands.”
The Suzhou lab features direct-drive 19mm and 24mm single screw extruders, each with a polymer melt pump, a sophisticated three-layer spiral flow tubing die, PLC line control with data acquisition, precision vacuum sizing tank for both rigid and flexible products, closed loop ID/OD control via an ultrasonic gauging system, a servo controlled combination puller/cutting system, and a transport conveyer with single-zone air eject. It also includes a single layer tubing line designed specifically for the production of FPVC tubing for IV and fluid delivery applications. Products ranging in size from 2mm OD to 8mm OD can be produced with an accuracy of +/- 50u at line speeds up to 100mpm. Davis-Standard’s facility in Pawcatuck, Connecticut, also has a fully equipped medical tubing laboratory.
Both laboratories support applications for Alternate Polymer, microbore tubing, multi-lumen and catheter tubing, edotracheal and tracheotomy tubing, radio opaque tubing, bubble tube, taper tube, pipette tubing and multi-layer tubing, among others. Complete medical tubing systems support extruder outputs up to 315kg/hr (700 pounds per hour) and line speeds up to 240 mpm (800 feet per minute) for a range of materials including PLA, PLLA, PEEK, FPVC, polyurethane, nylon, PEBAX and FEP.
