Water Glass Investment Casting
Water Glass Investment Casting
Introduction
Water glass casting is one of the most common investment casting processes in China, but it is rare in other countries. In China's foundry foundry, about 80% of foundries focus on water glass casting, and the rest are silica sol foundries.
Water glass casting is a lost wax investment casting process that uses water glass as the binder for the shell. The lost wax process keeps the casting surface and internal inspection at a relatively low cost. The origin of water glass casting is in Russia. It is suitable for steel castings, especially carbon steel and alloy steel castings. It allows the production of steel castings from 0.5kg to 60kg.
