Control de temperatura para máquinas de rotomoldeo

Abstract

One of the most commonly used plastic modeling methods is rotational (rotomolding). Where, hollow pieces are produced from pouring plastic powder or liquid into a mold that rotates in two axes while heating. This is a temperature highly dependent process, due to any temperature variation can cause inaccuracies in the final product. For this reason, in the present work a control is proposed to keep the temperature stable regardless of the disturbances that may appear. For this, an Arduino-based dynamic closed loop control system was designed. By adjusting the burners temperature values of the system by using servo valves. The proposed system was validated in the production process of 750-liter domestic water tanks. Taking into account the burners response to achieve the operation point, as well as the quality of the resulting tinacos.
