Effect of the conditions of ultrasound seam welding of polymer films on weld formation and process productivity

Abstract

A technology of ultrasound welding of film materials is developed. It is shown that the parameters influencing the productivity of the process of ultrasound seam welding of polymer films are the amplitude of oscillations, welding pressure, welding speed and the length of the end of the waveguide in the welding direction. The experimental results show that with increase in the length of the contact spot of the end of the waveguide the speed of seam welding increases linearly.
