Computer Simulation of an Impulse Heat Sealing Machine

Abstract

Reduced computing costs and continued development of computational methods of heat transfer make it possible to simulate complicated heat sealing processes on a computer. Such a simulation is developed for an impulse heat sealing machine and is used for a parametric study of the magnitude and duration of the heat pulse and the length of time the clamping jaws remain closed after the heating period ends. The results (i.e., the temperatures at critical points in the material being sealed) are shown to be useful in setting initial design specifications for the impulse heat sealer.
