? 2022 Elsevier LtdHigh-pressure injection molding is an important industrial process, which requires a precise cooling stage. In this work, we analyzed the reasons for the corrosion failure of the cooling circuit of molds in the molding plant. The cooling circuit was inspected visually and collected samples were further analyzed in a laboratory using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). The main problems were an improper selection of the antibacterial agent and materials of the cooling circuit. Based on the performed analyses, a possible mechanism of the corrosion attack was proposed and recommendations to decrease the number of corrosion-related failures and services were formulated.
