<![CDATA[General Background: Industrial automation relies heavily on reliable and efficient electrical control systems to maintain smooth operational workflows. Specific Background: Packaging machines require dedicated electrical control panels capable of managing sequential operations such as film pulling, temperature regulation, and material filling. Knowledge Gap: Small and medium enterprises frequently encounter challenges in designing specialized electrical panels that integrate conventional relay-timer systems with rigorous industrial safety standards. Aims: This study aims to design and construct an electrical control panel for packaging machines to regulate the packaging process. Results: Applying an experimental methodology through component selection, assembly, and functional testing revealed that the designed electrical panel successfully operates the packaging machine with high precision and integrated safety protections. Novelty: This research provides an empirical framework for implementing a cost-effective, relay-timer-based electrical control system tailored for vertical semi-automatic packaging machines. Implications: Deploying this structured electrical control panel ensures responsive system performance, supports compliance with occupational safety regulations, and provides a viable economic alternative for industrial automation. Key Findings Highlights The electrical control panel successfully regulates vertical packaging machine operations with high timing accuracy and responsive control. Integrating digital thermostats ensures stable heater temperature distribution, preventing seal defects during continuous production runs. The relay-timer configuration delivers a cost-effective automation alternative, reducing capital investment compared to complex programmable logic controllers.
