사출 금형 히터의 센서 기반 제어 방법 연구
Abstract
This study presents the development of an innovative control methodology for heaters used in molding processes. The conventional methodology for regulating heater temperature employs an on/off mechanism, which results in considerable temperature fluctuations across different regions. Hence, a control method is developed to minimize the temperature deviations between regions during the heating process. Applying this method to a sample mold reduced the temperature deviation by up to 69% without increasing the preheating time. Moreover, the efficiency of the proposed method is confirmed from the filling and curing processes. During the filling process, the maximum and minimum temperatures decreased by approximately 5%, respectively, thus indicating a reduction in temperature variation during the process. During the curing process, the minimum cure degree improved by approximately 91%, as evaluated based on the cure degree of the product.
