| Abstract: | The cooling process of the extruded bars of amorphous plastics with rectangular section was simulated based on heat transfer theory and finite difference method. A three-dimensional model of the transient temperature profile on the bar in cooling water was formulated. The model was numerically solved and an effective cooling technique was determined. |
