Dukane's servo-controlled ultrasonic welder allows for better repeatability than pneumatic systems.

Today at MD&M West, Dukane Corp. (St. Charles, IL) announced the launch of a servo-controlled ultrasonic welding technology designed with the company's Melt-Match technology. The system is designed to offer better repeatability, reduced manufacturing costs, and improvement in validation and calibration as compared with pneumatic ultrasonic equipment. Enabling these system benefits is the Melt-Match technology, which allows for the precise control of the collapse speed. Optimizing the collapse speed during the weld and the hold phase yielded stronger pull test results, according to the company.To support its claims, Dukane conducted an experiment in conjunction with a medical device manufacturer client. The client first welded a polycarbonate filter housing using Dukane's servo-controlled system and then performed the same action employing a pneumatic machine. The customer's results revealed that Dukane's servo-controlled system with Melt-Match technology had an average standard deviation of 1.9%. In contrast, the pneumatic system had an average standard deviation of 6.6%, according to Dukane.The product is housed in the company's iQ-series power supply, which is capable of processing at speeds up to 0.5 ml/sec. Furthermore, because the servo-controlled system does not require compressed air for actuation, energy costs and carbon emissions are reduced.
