Quick answer: Lower frequency = greater amplitude and more energy per cycle, so 15kHz suits large or thick parts; 20kHz is the all-round choice for general plastic assembly; 35–40kHz delivers low amplitude for delicate, small or electronic components. The fastest way to decide: look at your part size, wall thickness

Ultrasonic Plastic Welder The welding principle of ultrasonic plastic welder is to convert 50/60 Hz current into 15, 20, 30 or 40 kHz electric energy through an ultrasonic generator. The converted high-frequency electric energy is again converted into mechanical motion of the same frequency through the transducer, and then the

It is particularly important to debug before using the ultrasonic plastic welding machine. If the debugging method is not correct, problems may occur during use. Next, let’s learn together what debugging work is required before operating the ultrasonic plastic welder? Connect the ultrasonic wire and control wire between the ultrasonic

Turn on the air pressure of theultrasonic plastic welding machineand maintain a certain air pressure. Use tools to remove the original welding mold from the welder, install the ultrasonic mold of the product to be welded, and ensure that the contact surface between the mold screw of the ultrasonic plastic
