Abstract
"Considered for years as a metal casting renegade, Expendable Pattern Casting (EPC) is believed by some to be tomorrows long-term casting future. Others, however, see it as an unproven headache-ridden process that makes the simple art of metal casting unnecessarily complex." (Lessiter, 1994, p. 36). The complexity of this process has been largely due to the lack of knowledge surrounding the interaction of the metal front and the dissipating polystyrene pattern.
Since the discovery of EPS as a pattern material, numerous applied research projects have been performed to gain a better understanding of the thermal breakdown characteristics of the material. As a result, knowledge of the reaction is much more thorough today than it was some thirty years ago, yet numerous other problems remain unsolved. Still EPC holds promise as a casting process of the future. The problem of this study is to identify if the loose-sand, vacuum assisted, counter gravitational casting method can be used to cast EPS patterns effectively.
