Class Information
Number: 264/442
Name: Plastic and nonmetallic article shaping or treating: processes > Direct application of electrical or wave energy to work (e.g., electromagnetic wave, particulate, magnetic, induction heat, sonic, electrostatic energy, etc.) > Using sonic, supersonic, or ultrasonic energy
Description: Processes directed to utilizing wave vibrations which cover the use of (a) frequencies above the range of normal human hearing, usually above 20,000 hertz and below radio waves (i.e., supersonic or ultrasonic), or (b) frequencies which can be heard by the human ear (from about 15 hertz to approximately 20,000 hertz).
