The first step in the defect analysis is to identify the major casting defect among the many casting defects. Then the analysis is to be made to find the root cause of the particular defect. Moreover, it is especially difficult to identify the root causes of the defect. Therefore, a systematic method is required to identify the root cause of the defect among possible causes, consequently specific remedial measures have to be implemented to control them. This paper presents a systematic procedure to identify the root cause of shrinkage defect in an automobile body casting (SG 500/7) and control it by the application of Pareto chart and Ishikawa diagram. with quantitative Weightage. It was found that the root causes were larger volume section in the cope, insufficient feeding of riser and insufficient poured metal in the riser. The necessary remedial measures were taken and castings were reproduced. The shrinkage defect in the castings was completely eliminated.}, type={Artykuły / Articles}, title={Investigation of Shrinkage Defect in Castings by Quantitative Ishikawa Diagram}, URL={http://journals.pan.pl/Content/101989/PDF/afe-2017-0032.pdf}, doi={10.1515/afe-2017-0032}, keywords={Casting, Shrinkage defect, Pareto chart, Ishikawa diagram}, }
