Modeling and Simulation for Cooling System of Thermoforming

Thermoforming is one of the most versatile and economical processes available for polymer products. The cooling process is one of the key processes of thermoforming which effects to quality of final products. In this study, two kinds of 1-d analysis models were developed under the condition of checking the possibility of changing a 2-d to a 1-d problem in a previous study. At first, a model for stability analysis of the cooling system was developed under the condition of considering ABS sheet and mold as lumps. In order to get time-dependent temperature distribution of ABS sheet, another model was developed. The 1-d analysis codes can be widely used for designing the cooling system of thermoforming.
