Application of ultrasonic plastic welding machine
Nowadays, industrial automation is inseparable from the ultrasonic welding process. Ultrasonic welding uses high-frequency vibration to transfer energy to the surfaces of two objects to be welded. Under pressure, the surfaces of the two objects are rubbed against each other to form a fusion of molecules. . Shanghai Jiaocheng uses a variety of frequency specifications of ultrasonic plastic welding equipment and customized various welding heads to meet the different needs of customers.
Principle of ultrasonic plastic welding machine:
Ultrasonic plastic welding machine converts 50/60 Hz current into 15KHZ, 20KHZ, 30KHZ, 35KHZ, 40KHZ high frequency signals through ultrasonic generator. Through the energy conversion system, the electrical energy is converted into high-frequency vibration mechanical energy, which is simultaneously applied to the plastic product by air pressure, and the temperature rises through the friction between the molecules in the surface of the product. When the temperature reaches the melting point of the product itself, the product is made Fast fusion. When the vibration stops, the product keeps cooling under a certain pressure, so as to achieve effective welding. The welding time and welding head pressure of the ultrasonic plastic welding machine can be adjusted, and the amplitude is determined by the selection of the amplitude modulator (amplifier).
