Solutions to the transient heat conduction equation subject to surface cooling and radiant heating are presented. The problem is associated with industrial methods of heating semitransparent plastic sheets for thermoform processing. Three cases are detailed: symmetric heating, unsymmetric heating, and pulsed, or “on-off,” heating. The results demonstrate the effects of several parameters on the heating characteristics of the sheet. The method employed and solutions presented can serve to optimize thermoforming processes.
