Soluble core for high-pressure casting and manufacturing method thereof

Abstract

According to the method for manufacturing a soluble core for high pressure casting, the method for manufacturing a core by dispersing a heat-resistant hard ceramic powder in a water-soluble chemical salt having a melting point 140° C. to 260° C. lower than a melting point of a cast metal and a heat capacity of 90 J/(mol·K) or more is a very useful technology that can easily manufacture a core for high pressure casting of metals such as aluminum and magnesium, and a method for extracting a core from casting can also be simply performed by heating and extracting the core at a temperature equal to or lower than the melting point of the cast metal, and since the core material can be recycled, it is very advantageous in terms of productivity and economy.
