Low Pressure Casting

In low pressure casting, the mold is located above the sprue and metal flows ''up'' the sprue and into the runner system and the casting cavity(s), (Fig. 7.9).The metal flow for the arrangement shown in Fig. 7.9 is accomplished by pressurizing the furnace, which is located below the mold. The rate of metal flow is controlled by the rate of pressurization of the furnace.
