Ultrasonic welding machine
From Plastics Wiki, free encyclopedia
An ultrasonic welding machine consists of four main components: a power supply, a converter, an amplitude modifying device (commonly called a Booster) and an acoustic tool known as the horn (or sonotrode).
Power supply
The power supply changes mains electricity at a frequency of 50-60Hz, into a high frequency electrical supply operating at 20, 30 or 40kHz. This electrical energy is supplied to the converter. Within the converter, discs of piezoelectric material are sandwiched between two metal sections.
Converter
The converter changes the electrical energy into mechanical vibratory energy at ultrasonic frequencies.
