Definitions for "Ultrasonic welding"
Ultrasonic vibrations are produced by mechanical motion of a converter, expanding and contracting some 20,000 times/sec. The vibratory energy is channeled through a horn and applied to thermoplastic materials. This creates the frictional heat to produce a molecular interaction and weld materials.
Process using vibratory mechanical pressure at ultrasonic frequencies (20 to 40 kHz) to provide heat for welding some types of thermoplastics. See also ultrasonic bond.
A method of joining plastics using ultrasonic vibrations which are produced by the mechanical motion of a converter expanding some 20,000 times per second. The vibratory energy creates frictional heat which is channeled through a horn and applied to thermoplastic materials to produce a molecular interaction that welds the materials.
