Investment Casting

Description

What is precision casting process?

Precision 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.

China water glass investment casting process

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

The Silica Sol precision 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.

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.

First article layouts and spectrometer material certifications are provided with all first article samples.

Custom service: A variety of secondary operations can be performed on both types of precision investment castings. They include heat treatment, machining, plating, painting, polishing and buffing, assembly services and even custom packaging.

Metal used for precision investment casting process:

Metal for investment casting
Stainless steel precision casting	Stainless steel is a popular choice for investment casting because it’s durable and resistant to corrosion.
Carbon steel precision casting	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 precision casting	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 precision casting	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 precision casting	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.
