Abstract
Phosphate bonded investments are widely used in casting the high- fusing alloys. After casting it always have positively cast nodules on the surface of casting, which cause the fitness of the casting on the die. The purpose of this article is examine the effect of a number of investing variable on the incidence of bubbles cast to wax patterns invested in a phasphate bonded investment. The result of this study showed that the minimum number of adherent bubbles may be achieved by machine mixing investments using a high liquid/powder ratio, and by treating wax patterns with debubblilizer prior to investing them.
