The production of injection moulding components for the automotive market, meeting the highly demanding requirements of the industry, requires a continuous capacity of investment in the maintenance of the machine park. Although many companies perform this maintenance in a corrective lens, others already use the more sophisticated tools that have to avoid possible problems during the manufacturing process, ensuring levels of production and quality required by the automotive industry. This report presents the contributions obtained during an internship in a company of production of injected casting components for the automotive market and whose objective was to apply the methodology of analysis of the mode of failure, effects and criticality (FMECA – Failure mode effects and criticality analysis) to one of the company's most critical machines, the vacuum pressure die-casting machine Work begins with the understanding, in terms of operation and purpose, of the machine under analysis. Subsequently, and given its vital character for the high performance of the vacuum die-casting machine, an analysis is made of the type of failures that may occur in the vacuum equipment of the machine The FMECA methodology is applied to the vacuum equipment in order to identify its potential failure modes and to evaluate the effects that these failures may have on the foundry machine. The contributions resulting from the application of the FMECA methodology gave rise to a specific control plan for the detected problems and to a schedule and mandatory equipment maintenance.
