专题见解

Ultrasonic weldingis one of the most widely used processes for bonding polymers, valued for its speed, flexibility, and low cost. Recently, there has been a call for more controlled and consistent ultrasonic welding processes, as part designs become more complex and requirements more stringent

Dukane Corporation has taken a significant step to improve the ultrasonic industry’s standard test part. They’re calling it the ISTeP, a two-piece cylindrical part used to test a variety of welded parts’ characteristics. With ISTeP, ultrasonic weld quality and reliability can be determined with e

Dukane Corporation donated apneumatic ultrasonicwelder and loaned aservo-actuator controlled ultrasonic welding systemto David Grewell’s bioplastics research group. The new equipment will be used to study various control algorithms for cutting polylactic acid (PLA) films. Th

QUESTION: I’m getting inconsistent parts even though I’m following the same parameters. Why?ANSWER: You need to look at all elements of the project in order to pinpoint the problem. We suggest looking at the molded parts for warpage, heat sinks and cavity-to-cavity variations. Look at thejoi

QUESTION: In a staking operation, I want the stud to melt at the face of the horn to form a rivet head. Instead, it’s melting at the base of the stud. What’s going on?ANSWER: A couple of things. First, energy is transmitting through the stud to the base. Try pre-triggering the system so that the h

Leo Klinstein, Director of Engineering at Dukane Corporation recently spoke at the2012 UIA 41st Annual Symposiumin San Fransisco, CA. The UIA Symposium is a 3-day symposium that provides a networking opportunity for ultrasonic professionals and colleagues throughout the world. There is t
