Gravity casting
Gravity casting is a metal casting process. Its core principle is to utilize Earth's gravity to inject molten metal from a gating system into a metal mold.
Unlike die casting, which requires high pressure to force metal into the mold, gravity casting relies entirely on the weight of the molten metal itself to fill the mold cavity. This makes the production process relatively smooth, resulting in a denser internal structure in the product.
Main characteristics of gravity casting
Good surface finish: Due to the smooth inner wall of the metal mold.
Excellent mechanical properties: Due to the rapid cooling rate of the metal mold, the casting has finer grains, a denser structure, and higher strength and hardness.
High dimensional accuracy.
Applicable materials: Primarily used for non-ferrous metals such as aluminum alloys, magnesium alloys, and copper alloys.
Main application areas
Parts produced by gravity casting are widely used in various industries, especially in areas requiring strength, sealing, and surface quality:
Automotive industry: Engine cylinder heads, pistons, wheel rims, brake calipers, gearbox housings.
Motorcycles: Engine crankcases, cylinder heads.
Electronics and communications: Radiators, housings.
Home appliances: compressor housings, washing machine counterweights.
Aerospace: various high-requirement aluminum alloy structural components.

Heavy Forging Press Capacity
Our heavy-duty forging presses support open-die forging and deformation of large-section forgings, including discs, shafts, blocks, and custom components. This capability enables us to meet the demanding forming requirements of heavy industrial applications.
Heat Treatment Capability
Heat treatment is a critical step in achieving the mechanical properties required for heavy-duty forgings. Our process capabilities meet the strength, toughness, and structural stability requirements for forged components used under demanding operating conditions.
Heavy Shaft Machining
We offer machining capabilities for large forged shafts and long cylindrical components, supporting both rough and finish machining. This capacity is suitable for stepped shafts, rotor shafts, rollers, and other heavy-duty forged shaft components.
Ring Forging Machining
Our machining facilities are capable of handling large ring-shaped forgings and circular parts that require precise turning, face machining, boring, and contour control. This capability is suitable for industrial ring blanks, heavy-duty circular parts, and machined ring forgings.
Cylindrical Forging Machining
We offer machining solutions for heavy-duty cylindrical, hollow, and tubular forgings. This capability supports the machining of sleeves, cylinders, and other thick-walled forged components used in pressure vessels, rotating systems, and general industrial applications.
Inspection & Testing
Quality control is integrated into our production process through the inspection and testing of forged and machined parts. Our capabilities help verify the dimensional accuracy, condition, and quality consistency of industrial forgings prior to delivery.
Packing & Delivery
Finished forgings are properly protected and packaged to minimize the risk of damage during storage and transportation. Our packaging methods ensure the safe domestic delivery and export shipment of machined and high-value forged components.
