Abstract
The article is focused on the use of Quality Management tools to identify causes of formation deviations dimensions in cylinder head castings. Moreover, methods of production of castings made from alloy AlSi9Cu1, heat treatment of castings, as well as requirements of their quality are described. Research of the influence heat treatment parameters on the changes of castings' dimensions, with using Quality Management tools (Ishikawa diagram) is described too. In order to optimize the process for eliminate of deviations, experiment for modelling parameters of heat treatment was designed. The results processed in the Pareto diagram clearly pointed out the causes. Dimensional deviations were created during the heat treatment process. We have found the largest distortions in castings were created during rapid cooling. The article gives important information about using of research results in the production of cylinder head castings.
