Brass Investment Casting

Part name: Brass investment casting connetcor

Metal casting process: Lost wax investment casting process

Brass investment casting is a metal casting process that uses wax models to create precise, lightweight, and required parts using molten brass. Brass is a popular choice for investment casting because it’s versatile, corrosion resistant, and has a low melt temperature and viscosity. Brass investment casting will be used for valves, pumps, boilers, railway, plumbing and marine. Please mail your inquiry to gina@guokuncasting.com or call us 86-18132789710( WhatsApp or Wechat)

Bronze Castings

Description

Brass (C83300-C87900) are copper alloys in which zinc is the principal alloying addition. Brasses may also contain specified quantities of lead, tin, manganese and silicon. There are five subcategories of cast brasses, including:

Copper-Tin-(Lead)-Zinc Alloys: C83300-C83810 and C84200-C84800, the red and leaded red brasses and semi-red and leaded semi-red brasses, respectively;

Copper-Zinc-(Lead) alloys: C85200-C85800, yellow brasses and leaded yellow brasses

Manganese bronze and leaded manganese bronzes, C86100-C86800, also known as high strength and leaded high strength yellos brasses;

Copper-Silicon alloys: C87300-C87900, which are called silicon brasses, or silicon bronzes if they contain more silicon than zinc. Silicon Brass Investment Casting

The machined brass casting parts are with resistance to corrosion and rust, high strength and wear-resistance, good electrical conductivity and superior machining and polishing characteristics. So the brass casting components can be used in may industries, such as pump, valve, gears, engine, marine, etc.

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.
