A Study of Auto Pour in Sand Casting Process

Abstract:

Metal casting is a process of metallurgical forming by liquidize of material up to certain high temperature to achieve perfect chemical reaction and high level quality products. Auto pour means pouring the metal liquid into the mould not by manual operation but more than automatically done by a set of machine without any human intervention. This paper aims to describe the process of automation for brake drums where several parameters are compare with manual process. The standard time, cycle time, rejection rate, dimension, chemical composition and product quality have been analyzed. The results shows that the standard time reduce to 40%, rejection rate less 5%, tensile strength 3% higher because of better pouring process. The other parameters are the same for both manual or automatic pouring process. The conclusion of this research is that the auto pour provides better results in term of productivity and quality.
