In this work, a temperature control system (SCT) was designed and implemented in the thermoforming process for the manufacture of blocks for wall construction (BCM). The control process in the SCT consists in establishing the reference temperature for the thermoforming and send it to the Mega 2560 microcontroller. This component processes the input signal, obtaining six digital signals that control the surface temperature of each of the external faces of the BCM mold that has a rectangular prism geometry. These signals are sent to the electrical isolation stage where the actuators enable six electrical resistances (200 Watts to 120 Volts). The feedback of the temperature in the control system was made through type-k thermocouples, whose analog signals are compared with the reference signal to regulate the temperature. This project contributes to establish and control the temperature of the resistances, implemented for the thermoforming process, for the elaboration of blocks using multilayer containers.
