lost foam casting materials

The lost foam casting materials are used for lost foam coating is typically ordinary dry quartz sand, a dry powdered, environmentally friendly coating. It consists of composite refractory powder, along with a blend of organic and inorganic binders and suspending agents. This coating offers excellent properties such as suspension, adsorption, thixotropy, quick drying, air permeability, brushability, leveling, and high resistance to molten steel and cracking at elevated temperatures.

lost foam casting process producing guide

Note: To prevent mechanical sand sticking, a layer of refractory coating must be applied to the surface of the lost foam pattern. During casting, this refractory layer acts as a critical barrier between the molten metal and the molding sand. It plays a vital role in the gasification of the lost foam pattern, the flow of molten metal, and the successful formation of the casting.
