Description

What is copper-based alloy investment casting?

The copper-based alloy investment casting is the copper casting components produced by lost-wax investment casting techniques or silica sol precision casting process. The copper investment casting components are with good corrosion resistance, ductility and conductivity. Baoding Guokun can use investment casting process to produce the copper alloy casting parts for pump housing, pump parts, pump impeller, valve body, valve disc, marine, engine and other industrial casting parts.

What is copper base alloys?

The coppers (C80100-C81200) are high-purity metals with a minimum designated copper content of 99.3%. The copper investment casting has many advantages, including corrosion resistancem high conductivity, excellent apperance and others.

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.

Investment Casting Process Steps

The process of Baoding Guokun Investment casting involves several steps after producing a professional tool or mold in high-grade aluminum alloy, including:

No.	Steps	Details
1	Patterns Makings	Hot wax is poured into the mold patten and allowed to harden, and then adding sprues to the wax model to create a tree-like structure.
2	Shell Building	Coating the wax pattern with a layer of fire-resistant paint, and then to be sprinkled with sand, so after a period of hardening, the surface will form a layer of fire-resistant thin shell.
3	Dewaxing	Removing the wax, the shell is placed into an oven, melting the wax so that it can run out of the shell.
4	Pouring	Pouring the molten stainless steel into the shell, and waiting for solidification under room temperature.
5	Post treatment	After cooling, knock the shell and cut the sprue gate by grinding machinery to achieve net shape impeller castings. Then shot blasting to move mill scales to assure the smooth casting surface.
6	Machining	CNC Machining

Advantages of Lost-wax investment casting

High dimensional accuracy: Investment casting can achieve dimensional accuracy of about +/-0.005 in per inch, more precise than sand casting process.

Excellent surface finish: The investment casting produced by Baoding Guokun can achieve excellent casting surface finish of 125 Ra, which often can eliminate the further machining’s need.

Extremely complex and intricate metal parts are castable: Investment precision casting process can create complex geometries and intricate designs.

Widely alloy selection: Almost any metal can be casted, for example, low-carbon steel, mild steel, alloy steel, stainless steel, even aluminum, brass and bronze.

No flash or parting lines should exist: Compared with close die forging or mold forging parts, the investment casting parts are with no flash and parting line. This will help to improve the effective utilization of metals and enhance surface aesthetics.

Low Cost: The investment casting of Baoding Guokun is cost-effective because that our steel investment casting parts are with near-net shape, high production yield, fine surface finish and reduced machining needs. And investment casting process has lower tooling or mold costs than other metal casting methods.

Copper alloy castings work best with investment casting but sand casting and centrifugal casting process is also avaible. Baoding Guokun metal casting factory can produce the aluminum bronze, red brass and copper based alloys for large production runs for complex components, for example, pump housing, pump casing, pump volute, pump impeller, vane impeller, valve body, valve disc, pump bearing frame, marine bushings, crusher bushings, etc.
