Gas permeability of moulds and cores is an important factor to consider in the casting process. In foundries, gas measured by using instruments which give dimensionless numbers. This approach enables comparison values between samples often not quantified units. this study, a custom-made measurement system introduced that applies Darcy’s law, where pressure gradients for different flow rates are...

This research study sought to determine the strengths and weaknesses of the current maintenance practices at a sand casting manufacturing company which is principally a ferrous foundry producing grey and white iron. The work suggested good practices which could be taken on board and others which could be improved on. The generated recommendations can be used by other foundries to enhance their ...
