Factors Leading to Major Casting Defects and their Influence on Productivity of Foundry

In recent times, with the constant utilization of natural resources, every manufacturing unit is turning towards a lean approach. Foundries are no exception to this. Although the fundamental responsibility of a foundry is simply to convert raw metal into a useful casting, it is imperative on their part that the output confirms with the quality as desired and is free from defects of any kind. However, there may be factors like the rate of cooling of molten metal being poured, mould properties, metallurgy of the molten metal being poured and the mould geometry and rigidity to name a few which may have their influence on the casting quality and the overall productivity of the foundry. While striking a balance between the quality and productivity, there may be certain deviations undertaken from the regular course that may lead to casting defects. This paper intends to highlight such interdependencies and suggest indirectly the most feasible means to control casting defects in order to ensure attainment of both quality and productivity. Casting defects considered for this work shall be those observed at a major scale and those which require adequate attention on account of frequency of occurrence. A conclusion shall be drawn towards the end dictating the major findings of the study.
