Principle of Ultrasonic Plastic Welders:

Ultrasonic plastic welders operate by inducing ultrasonic frequencies in plastic components that is converted into heat between the welded plastic laminates. Frictional heat is produced so that thermoplastic parts melt and an insoluble connection between parts is forged in a very short period of time. The melting points of both working pieces is nearly equivalent which helps to form a uniform weld area. The welded area is usually as strong as the matrix material.
