A composite horn is actually a half-wave “coupler” horn with two or more half-wave, tuned horns attached to it. This technology was patented by Dukane in 1973. Because composite ultrasonic horn designs can often eliminate the need to invest in additional assembly systems, they reduce equipment costs and minimize production time for customers. Composite ultrasonic… Continue Reading Composite Ultrasonic Horns
The 39th Annual UIA (Ultrasonic Industry Association) Symposium held in Cambridge, MA, included 80 participants from 48 organizations representing 11 countries. The program included one day of industrial presentations on Monday April 12th, two workshops, a poster session on Tuesday April 13th and a day of medical presentations on April 14th. Dukane was a proud… Continue Reading Dukane Participated in 2010 UIA Symposium
The most important factor in troubleshooting problems in ultrasonic welding is understanding the fundamentals of the process. With this basic knowledge, most problems can be easily diagnosed and resolved. Even so, sometimes your time-tested weld recipe may suddenly fail for no discernible reason. Perhaps your ultrasonic welder has been running the same application for months,… Continue Reading What Happened to Your Ultrasonic Weld Quality?
Ultrasonic Probe Plastic welding is the most common application of ultrasonic assembly. To perform ultrasonic plastic welding, a vibrating tip is brought into contact with one of the work pieces as shown in Figure 1–1. Pressure is applied and ultrasonic energy travels through the material, increasing the kinetic energy (or heat) at the contact point… Continue Reading How does your Ultrasonic Probe/Stack work?
Users of ultrasonic welders and ultrasonic cleaners inquire, from time to time about the effect of ultrasonic energy on the health of the operator. This paper is a brief summary of the nature of ultrasonics and its potential effects on health. The Nature of Ultrasonic Energy Ultrasonic energy is mechanical energy as contrasted with other… Continue Reading What are the effects of Ultrasonics on your Health?
When considering a new piece of equipment, it is not all that different from shopping for a new car. Should I buy new, or will used be okay? I don’t want to overspend, but I don’t want to get stuck with a lemon either. The answer starts with an assessment of needs. Is this the… Continue Reading New or used equipment? Buy or lease? How do I decide?
