Cast gray iron is a type of cast iron which made up of carbon, silicon, and manganese. The grey iron is the most common cast iron and is named for its gray color when it fractures due to the presence of graphite flakes. Due to high thermal conductivity, excellent vibration damping, good corrosion resistance, and easy to machine, the cast gray iron is mainly used for automotive, construction, cookware, pump, valve, truck, agriculture, mining, such as gearbox housing, pump shell, valve body, motor housing, etc.

Gray cast iron: ASTM A48 Standard Specification for Gray Iron Castings

This specification covers gray iron castings intended for general engineering use where tensile strength is a major consideration. Castings are classified on the basis of the tensile strength of the iron in separately cast test bars. The casting surface shall be free of adhering sand, scale, cracks and hot tears, as determined by visual examination.

Baoding Guokun can use grey cast iron to produce the following products:

Pump casting: Pump casing, pump housing, pump shell, pump back liner, pump cover plate, hydraulic pump parts and other customized pump replacement parts.

Valve casting: Valve body, valve seating, industrial valve fittings and other valve casting components.

Automotive casting: engine blocks, brake systems, brake disc, clutch plates, cylinder liners, and positions, etc.

Agricultural machinery casting parts: plow shares, tillers, irrigation system components, and other tractor casting parts.

Depending on your pump types and requirements, Baoding Guokun can cast and machine different pump replacement parts in heat-resistant stainless steel, ductile iron, gray iron, aluminum alloys and other metals.

What's the pump casing?

Thepump casingis a metal casting outer housing, pump volute or pump shell that holds a pump and protects the internal pump parts, allowing fluid to flow through while maintaining pressure and preventing leaks by sealing off the inside of the pump from the atmosphere.

The two main types of casings in centrifugal pumps arevolute casingsand diffuser casings. A very common classification of pump casings is the diffuser construction. A diffuser is actually a series of vanes surrounding the impeller which accepts the discharge of liquid from the impeller.

Guokun Casting, of Baoding Hebei is an ISO 9001-2008 registered iron and steel foundry &supplier of high quality carbon steel, cast iron and machined castings used in power, mining, railway, agricultural, tillage, truck, automobile, pump, valve, motor, pipe fittings and gear industry. Baoding Guokun has been specialized in the designing and manufacturing of various valve components for ball valve, gate valve, globe valve, butterfly valve, through conduit gate valve, knife gate valve, bellow valve, strainers and flow control components.

What is avalve disc?

The valve disc is an important movable component within avalve that controls the flow of fluid by either allowing it to pass through or block it, depending on its position; essentially, it's the valve components that directly regulates the fluid flow by creating aseal against the valve seat when closed.

A broad line of materials is offered and fabricated in Baoding Guokun.

Steel material ranges from cast steel, forged steel to special alloy steel like Monel, Duplex.

Cast iron materials in GG20, GG25 or ductile iron of GGG40, GGG50, etc.

Aluminum, brass, copper and bronze valve parts can be produced in our factory.

What's the best material for avalve disc?

Stainless steel is the most common valve disc material because of its anti-corrosive, anti-heat and anti-contamination properties. The Baoding Guokun stainless steel casting valve disc is made asinvestment casting process, or lost-wax casting process that results in asignificantly improved surface finish &casting tolerance and valve disc quality than other sand cast stainless steel valve disc and bronze valve disc.
Two types of investment cast processes: Silica Sol process and the water glass process.

The Silica Sol process is used to cast complex high-quality parts with requirements of avery good surface finish and close dimensional tolerances. This process can range from aweight of just afew 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 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: Avariety of secondary operations can be performed on both types of investment castings. They include heat treatment, machining, plating, painting, polishing and buffing, assembly services and even custom packaging.

Drop forging, also called closed die forging is ametal shaping process where aheated metal billet is placed between dies and struck by ahammer or press to form the desired shape. It is commonly used for high-strength components like hydraulic cylinder yokes, connecting rods, gears.
The hydraulic cylinder yoke is acritical component that connects the cylinder to other heavy-duty machinery, such as construction equipment, excavators, loaders, cranes, agricultural machinery, tractors, harvester, mining &industrial hydraulic lifting equipment.

Advantage of Baoding Guokun drop forged yokes

Superior strength: Grain flow follows the yoke's shape, enhancing structural integrity.

High durability:Resists fatigue, impact and heavy loads better than cast yokes or welded yokes.

Precision &consistency: Tight tolerances ensure reliable performance in hydraulic systems.

Cost-effective for mass production: Lower per unit cost compared to machining from solid billet.

Better surface finish: Reduced porosity compared to casting.

The pump impeller is the rotating component in the pump that directly transfers the energy from the motor into the fluid being pumped. Pump impellers are classified as one of three types: Open impeller, semi-open impeller, or closed impeller. Their classification is based on whether they have aprotective shroud or not.

Baoding GuokunInvestment castingstainless steel pump impeller's steps:

1. Patterns Makings: Creating awax mold of the desired stainless steel pump impellers, and then adding sprues to the wax model to create atree-like structure.
2. Shell Building: Coating the wax pattern with alayer of fire-resistant paint, and then to be sprinkled with sand, so after aperiod of hardening, the surface will form alayer 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. CNC Machining &Balancing

Lost-foam casting is atype of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax. The lost foam casting techniques take advantage of the low boiling point of polymer foams to simplify the investment casting process by removing the need of melt the wax out of the mold. Compared withinvestment casting methodandsand casting techniques, lost foam casting is one of the most cost-effective and environmentally friendly metal casting process for creating complex and intricate metal parts by using afoam pattern that evaporates when molten metal is poured into it.
Usually, the material of motor housing is cast iron ASTM A48 or ASTM A536 for the larger motor casing. But the material is no longer limited to steel and pig iron as in the past, the thin and lightweight stainless steel and aluminum alloy are also more popular.
