Precision spline shaft forging
Spline shaft forgings are precision components used to transmit torque and coordinate the motion between mechanical components. Its grooves or teeth precisely match with the hub or gear, forming a stable and efficient connection. Each spline shaft is formed using closed die forging technology, followed by CNC machining and heat treatment to refine the grain structure and improve strength. These shafts perform reliably in applications that require high precision and durability, such as transmissions, hydraulic systems, and heavy machinery.
Manufacturing process
Material selection - Choose alloy steel and carbon steel, such as 42CrMo, 4140, and 20CrMnTi, to achieve good fatigue strength and impact strength.
Closed die forging - forging the heated billet in a precision mold to form a dense and continuous grain flow.
Heat treatment - quenching and tempering can improve hardness, wear resistance, and toughness.
CNC machining - splines, keyways, and threads are machined with strict tolerances to ensure reliable fit in spline shaft couplings or transmission systems.
Inspection and Testing - Each spline shaft forging undergoes UT, MPI, and dimensional inspection in accordance with ISO 9001:2015 standard.

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.
