Abstract
In lost
foam casting process, polystyrene beads are heated to foam and the required
pattern is made by polystyrene foam, which is then coated with refractory and
placed in a flask backed up with un-bonded sand. The molten metal poured, takes
the shape of foam pattern by evaporative action of foam. Whereas in
conventional sand casting, a wooden pattern is used to create mold cavity and
the cavity is filled with molten metal to get the final shape of casting. In
this paper, an experimental analysis was done on lost foam casting process and
compared with sand casting processes. The main objective of this study is to
investigate and compare the physical parameters like dimensional accuracy,
surface finish, and quality of the final product obtained from lost foam
casting process and sand casting process. The results from both the processes
are observed and compared to find the accurate and precise process among the
two processes.
