• 602 Effect of Coat Strength on Dimensional Change of ALuminum Alloy Casting in Expendable pattern Casting Process

抄録

The effect of coat strength on the dimensional accuracy of casting in expendable pattern casting (EPC) process was investigated experimentally. The aluminum alloy casting of the simple shape with the rib was cast by EPC process, and the dimensional change of the casting from the model was measured. When the sand was filled tightly, the dimensional accuracy and the appearance of the casting were good independently of the reduced pressure in the flask. When the sand was filled loosely, the positive different dimension of casting from the model was caused. Under the reduced pressure, this tendency was more remarkable and the leaching of the molten metal by the crack of the coat was observed. When the coat with high bending strength was used, even if the sand was filled loosely the different dimensions of the casting were small.
