Foundry practice is the most economical and easiest way of transforming raw materials into finished products. The increasing demand on the quality of castings made of Al and Mg alloys lead to the technological development of the casting process. One of the advanced casting technologies, namely die-casting, allows for the elimination of defects, specifically the micro-porosity of the casting volume. Castings with complicated shapes and thin walls are cast by the die casting technology, where permanent moulds are exclusively used. One of many such available casting technologies is squeeze casting, which allows for the production of castings with the lowest proportion of defects.
