We offer a variety of solutions
From automotive and aerospace to agriculture, valves, and industrial tools—Longchao provides tailored forging solutions to meet the specific needs of different industries.
Forged components play a key role in industrial machinery, where high strength and durability are critical under heavy loads and repetitive motion. Forgings are widely used in construction equipment, mining machinery, presses, and material handling systems.
Common forged parts include drive shafts, gears, spindles, rollers, couplings, and bearing housings. These components are typically made of alloy steel and heat-treated to meet specific performance requirements such as wear resistance, fatigue strength, and impact toughness.
In automotive applications, forged components are widely used in areas subject to high impact and stress. A typical vehicle can contain over 250 forged parts, most of which are made from carbon or alloy steel.
These parts are essential in engine and drivetrain assemblies, including connecting rods, crankshafts, transmission shafts and gears, differential gears, drive shafts, clutch components, universal joints, and cross shafts.
Additional forgings such as camshafts, pinions, gears, and rocker arms are often selectively hardened to enhance performance and durability.
The oil and energy sector demands forged components that can perform reliably under extreme pressure, temperature, and corrosive environments. Forgings are used in drilling equipment, valve bodies, flanges, pump parts, and pipeline components.
Due to the harsh operating conditions, components are often made from high-strength alloy steels or stainless steel, with precision machining and rigorous testing to meet international standards such as API, ASME, and NACE. Forged parts enhance safety, reduce failure rates, and extend equipment life in oilfields and power plants.
Forgings are essential in a wide range of general-purpose industrial equipment, including pumps, compressors, gearboxes, and lifting systems. These applications require parts that combine strength, precision, and cost-efficiency.
Typical forged components include shafts, gear blanks, flanges, yokes, and brackets. With flexible production capabilities, Longchao can meet both low- and high-volume demands while maintaining consistent quality for various equipment manufacturers.
