What is Silica Sol Investment Casting?

Silica sand casting is a casting process that uses silica sand (silica solution) as a binder to make the mould. Metal castings produced by the silica sand casting process have a fine surface and high accuracy, and the general dimensional tolerance is up to CT4 - CT6. This process is RMC's main investment casting process for stainless steel and alloy steel castings.

Application of Silica Sol Casting

Silica Sol is mainly used in precision casting because it has relatively high production costs but delivers very fine, precise dimensions, a good surface finish and overall very good quality.

So if you are looking for a way to produce small parts with high precision, high surface requirements and high corrosion resistance, and don't want to waste time waiting for the quality of your castings to gradually improve, then the Silica Sol investment casting process is definitely an option for you.

Advantages of Silica Sol Casting

Silica sol investment castings have a better size and surface quality, but are more expensive than water glass. As a rule, the cost is twice that of water glass.

Silica sol investment casting uses silica sand as the moulding material and the temperature resistance can reach 2000 degrees. This moulding material is very expensive.

The surface quality of silica sand investment casting is very good, very smooth, with very few surface and internal defects.
