Water glass casting is one of the most common investment casting processes in China, but it is rare in other countries. Among investment foundries in China, about 80% of the foundries focus on water glass casting, and the rest are silica sol foundries. So what is water glass casting?

Water glass casting is a lost wax investment casting process that uses water glass as the binder for the shell. Water glass casting originated in Russia. The water glass casting process is what we describe in the investment casting process, and this method is suitable for steel castings, especially carbon steel and alloy steel castings. It allows the production of 0.5kg-60kg steel castings.

Wax injection


For each casting to be made, molten wax is injected into the mold to create a wax pattern of the casting. The wax pattern is made of aluminum and its dimensions take into account the shrinkage of the wax and metal used. Wax tools range from simple two-piece molds to multi-cavity automatic molds and complex molds with water-soluble or ceramic cores.

Wax Assembly

Once the wax molds have cooled and stabilized to a stable size and shape, they are installed onto the gate or tree. The gate is also made of wax and contains all the necessary gates, runners and supports to adequately feed the part during casting.

Shell Building

Wax runners are now "invested" in ceramics to make molds for the metals to be injected. The ceramic consists of two parts, a liquid slurry covered with dry sand. Each runner is covered with layers of slurry and sand until the ceramic shell is thick enough to support it during casting. The shell making process usually takes 24 hours, with 2 days to nearly 2 weeks for the shells to dry completely.

Innovations in foundry process automation, such as the Universal Kinematics Sand Casting Adjuster, make it easier to machine large numbers of castings and improve casting quality

Dewaxing

Once the shell is completely dry, use an autoclave to melt the wax to counteract the expansion of the wax. The casing is then fired to remove any remaining wax residue and to cure the ceramic casing. Once the shells are fired, they are now ready for the casting process.

casting

The machined shell is placed back in the oven to preheat before casting. Once the shell is at the proper temperature and the molten metal has been prepared and qualified, the shell is removed from the furnace and the metal is poured into the shell.

finishing

Hammering, media blasting, vibrating, water jetting, or chemically dissolving (sometimes using liquid nitrogen) the shell releases the casting. The gate is cut and recycled. The casting can then be cleaned to remove traces of the casting process, usually by grinding.
