Porosity in Castings: Porosity may be the most persistent and common complaint of casting users. Forgings, machined parts and fabrications are able to avoid porosity with ingot cast feedstock, mechanical processing and automated inspection of simple shapes. Porosity in castings contributes directly to customer concerns about reliability and quality.

FILTERING MOLTEN METAL: Casting molten metal presents many opportunities for contamination, often with particles as small as a few microns. This contamination may be slag, dross, or pieces of refractory from the melting crucible. Metal that contains impurities will have reduced strength, and this usually requires a heavier section thickness to compensate for the lower strength. Impurities also present serious stress points if they are located on the surface of the castings that are subjected to mechanical forces.
Conceptual Framework for Designing Metal Castings: Well-designed castings are known to be functional as well as cost efficient. Yet, those directly involved in designing and producing castings know that the principles behind castings are difficult to pin down. “Rules of thumb” abound that attempt to define fillets, radii, changes in casting section, minimum section thickness, tolerance capability, estimating shrinkage for different alloys and unconventional solidification/heat transfer phenomenon undergoing at different shapes/contours of component casting.
