Introduction to Water Glass Casting
Water glass casting, also known as sodium silicate casting, is a widely - used investment casting process. In this method, water glass (sodium silicate solution) is used as a binder to make the shell mold. The process starts with creating a wax pattern of the desired part. Multiple wax patterns are usually assembled into a wax tree. Then, the wax tree is repeatedly dipped into a slurry made of refractory materials and water glass, followed by a coating of sand. After the shell has reached the required thickness, it is dried. The wax is then melted out of the shell, leaving a cavity in the shape of the part. Finally, molten metal is poured into the shell, and after solidification, the shell is broken away to obtain the cast part.
Water glass casting is favored for its relatively low cost, good dimensional accuracy, and the ability to produce complex - shaped parts. It is widely used in various industries such as automotive, machinery, and hardware.
