THE IMPACT OF TECHNOLOGICAL PARAMETERS OF DIE CASTING TO CASTING POROSITY

Abstract

The article deals with the research of the influence of selected technological parameters of die casting on the internal structure of die-casts based on Al-Si alloys. Among the chosen technological parameters of die casting is pressing piston speed and holding pressure. Examined castings internal structure is defined by the percentage of porosity. The article described the course design and preparation of metallographic samples to be investigated by optical microscopy. The measured values are given in tabular and graphical form. At the end of the evaluation is shown the impact of individual parameters on the internal structure and quality of the castings.
