Automated Control and Software Development for Precision Vacuum Casting of Reactoplasts in Small-Batch Production

This paper presents the development of an automated control system and software package for a vacuum casting unit designed for use with reactoplasts. The system addresses challenges associated with small-batch production, such as high mold costs and stringent quality requirements in industries like medical equipment and automotive manufacturing. Key components of the system include an STM32 microcontroller for real-time process management, servomotors for precise dosing and mixing, and a vacuum system to eliminate defects such as air bubbles in the final product. The developed software, implemented in Delphi, enables the operator to configure process parameters and monitor performance in real time, thus optimizing the production cycle. The system was tested with various polymer materials, showing significant improvements in efficiency, quality control, and reduction of production costs. The paper also includes detailed calculations for process stages such as vacuuming, mixing, and casting, demonstrating a reduction in overall cycle time to 13.5 minutes. These advancements position the system as an effective solution for enhancing productivity in small-batch manufacturing.
