Composite Ultrasonic Horns

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
