Stainless Steel Precision Investment Casting Foundry with OEM Custom Services and CNC Precision Machining Services

in the investment casting process, the water glass binder and coating have stable performance, low price, short shell-making cycle and convenient application. the water glass shell making process is suitable for the production of investment castings such as carbon steel, low-alloy steel, cast iron, copper and aluminum alloys that require less surface quality.

Water glass, also known as Sodium Silicate, is a kind of soluble alkali metal silicate, which is glassy in solid state and forms a water glass solution when dissolved in water. According to the difference of the alkali metals contained, there are two types of potassium water glass and soda water glass. The latter is easily soluble in water, contains less impurities, and has stable performance. Therefore, the water glass for investment casting is sodium water glass, namely Na20mSiO2, A transparent or translucent colloidal aqueous solution formed after hydrolysis. The main chemical components of water glass are silicon oxide and sodium oxide. In addition, it also contains a small amount of impurities. Water glass is not a single compound, but a mixture of multiple compounds.

According to the different binders for shell building, the investment casting could be divided into silica sol binder investment casting, water glass binder investment casting and the investment casting with their mixtures as binder materials.

Investment casting (lost wax casting) is a method of precision casting complex near-net-shape details using replication of wax patterns. Investment casting or lost wax is a metal forming process that typically uses a wax pattern surrounded by a ceramic shell to make a ceramic mold. When the shell dries, the wax is melted away, leaving only the mold. Then the casting component is formed by pouring molten metal into the ceramic mold.
