A brief analysis of the capabilities of the methodological evaluation of foundry technologies effectiveness is presented by the example of temperature condition adjustment of foundry procedure. It has been revealed that the methodological analysis as applied to different variants of foundry technologies allows determining the most effective ways of development of the foundry technology and increase in its efficiency. A reference to various examples shows the presence of the hidden reserves in foundry technologies. The authors conclude that the methodological analysis allows effective and timely adjustment in the development and modification of foundry technologies and enhancement of its effectiveness. The result of the conducted methodological evaluation is elaboration of the guidelines on the enhancement of foundry technologies effectiveness, aimed at the search of the hidden reserves of already functioning technologies.
