Silica sol investment casting

The Silica Sol investment casting process is used to cast complex high-quality parts with requirements of a very good surface finish and close dimensional tolerances. This process can range from a weight of just a few ounces to approximately 80 pounds. If you are concerned with precision in very small parts, we are especially proficient at very fine detail work including teeth and serrations. Silica sol wax is middle temperature, water glass wax is low tempearture. The major difference betwen the two investment casting process are in the surface roughness and cost of production. Compared with water glass investment casting, the silica sol casting method can be used to cast the complex-shape casting parts which offer design flexibility. And the componnets cast using silica sol typically have smooth and flawless surface finishes, reducing the need for additional post-proecssing.

What is Investment casting process?

Investment casting is an industrial metal casting process based on lost-wax precision casting, generally used for producing complex-shaped metal components that require tighter tolerances, thinner walls and better surface finish than other sand cast parts. Baoding Guokun can produce various investment casting parts in low-carbon steel, mild steel, alloy steel, stainless steel for pump, valve, agriculture, railway, road, forklift, tillage, mining, automotive, medical, food, and aircraft, etc.

Two types of investment cast processes: Silica Sol process and the water glass process.

The water glass casting process is typical of the process in the early stages of investment castings. It generally is capable of much larger castings than the Silica Sol process, but does not have as good of surface finish or tolerances. The water glass process provides parts that have better surface finish and dimensional tolerances than sand castings. This process may range in weight from several ounces to approximately 200 pounds.

Metal used for water glass investment casting process:

Metal for investment casting
Stainless steel	Stainless steel is a popular choice for investment casting because it’s durable and resistant to corrosion.
Carbon steel	Carbon steel is a low-cost material that comes in many grades. Heat treatment can improve the strength, ductility, and performance of carbon steel.
Alloy steel	Alloy steel is steel that is alloyed with a variety of elements in amounts between 1.0% and 50% by weight, typically to improve its mechanical properties.
Copper alloys	Many types of parts can be cast from copper-based alloys, such as brass and bronze. Beryllium copper is the strongest copper alloy and is resistant to corrosion.
Aluminum	Alloys like A-356, A-357, C-355, and F-357 are commonly used in investment casting. These alloys are resistant to corrosion and can be welded.
