Investment casting is developed on the basis of ancient wax casting. As an ancient civilization, China is one of the earliest countries to use this technology.
The so-called investment casting/Lost wax casting process, simply put, is to use fusible materials (such as wax or plastic) to make a fusible model (referred to as investment mold or model), and apply several layers of special refractory coatings on it, which are dried and hardened. After forming an integral mold shell, the mold is melted from the mold shell with steam or hot water, and then the mold shell is placed in a sand box, filled with dry sand molding around it, and finally the mold is placed in a roasting furnace for high temperature. Roasting (for example, when a high-strength mold is used, the mold after demolding can be directly fired without molding), after the mold or mold is fired, molten metal is poured into it to obtain a precision casting.
