Plastic Handheld Welding Spot Machine Ultrasonic Hand Gun Welder

Descripción del producto

The welding principle of ultrasonic spot welder is to convert *0/*0 Hz current into *5, *0, *0 or *0 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 mechanical motion is transmitted to the welding head through a set of amplitude modulator devices that can change the amplitude. The welding head transfers the received vibration energy to the joint of the workpiece to be welded. In this area, the vibration energy is converted into heat energy by friction to melt the plastic. The short pressure maintained on the workpiece after the vibration stops causes the two weldments to solidify into one body in a molecular link. Generally, the welding time is less than 1 second, and the obtained welding strength is comparable to that of the main body. Ultrasound can be used not only to weld hard thermoplastics, but also to process fabrics and films. The main components of an ultrasonic welding system include ultrasonic generator, transducer/amplitude modulator/welding head triple group, mold and frame.
