Dukane Corp.'s Ultrasonics Division has introduced what it claims it the first servo-controlled ultrasonic welding system for medical applications and other high-value parts.
The iQ welder is based on Dukane's new “Melt Match” technology, which delivers improved repeatability, stronger welds, easier calibration validation and lower manufacturing costs vs. standard pneumatic welders.
Melt Match precisely controls the collapse-speed profile during the weld. According to the company, collapsing too slow may cause material degradation while collapsing too fast could result in cold forming. Melt Match precisely matches the collapse speed during the melt phase — penetrating deeper into the bond and creating a larger affected heat zone, to give superior bond strength.
Typical pneumatic welders continue to travel during the hold phase, but a servo-controlled welder can stop and/or continue to collapse a specified distance and speed during the hold phase.
