ultrasonic transducer test

Plastic ultrasonic welding machine is a plastic workpiece processing, through the blessing of ultrasonic technology, applied to plastic workpieces to achieve the effect of welding. In order to pursue a good ultrasonic plastic mold, many factories will constantly debug the 20K Ultrasonic Plastic Welder to make its welding more accurate. There are many reasons that affect the welding process of ultrasonic welding machine, including ultrasonic vibration system, the transducer in this system has a great impact on welding, let's understand the ultrasonic welding machine transducer.

20k ultrasonic plastic welder, In the welding of plastic workpieces, plastic workpieces need high frequency longitudinal vibration, so that plastic workpieces up and down the mold can be up and down high-frequency vibration to produce melting phenomenon, forming a welding effect, so ultrasonic welding machine transducer - generally choose is longitudinal composite. The structure of the transducer is relatively simple, the end and end are two metal covers, the middle is composed of piezoelectric ceramic crystal stacks, these crystal piles are generally longitudinally polarized round tubes or circular perforated plates, of course, it may also be radially polarized round tubes, these three parts are tightly fixed by a stress screw.
