Forged Shafts We Manufacture
With comprehensive manufacturing capabilities, we support your unique design with precision and reliability.
Forged Step Shafts
Step shafts with varied-diameter steps optimize power transmission for gears and bearings. HDC Manufacturing ensures fillet continuity via precision forging.
Forged Hollow Shafts
Hollow shafts are widely used in the aerospace industry. By deep hole drilling, HDC Manufacturing ensures high coaxiality and uniform wall thickness, resulting in lighter weight and stable rigidity.
Forged Flanged Shafts
Flanged shafts serve in marine propulsion systems and heavy-duty generator sets. Through precision forging, we achieve integral molding, thereby avoiding welding problems and improving structural strength.
Forged Eccentric Shafts
Forged eccentric shafts are widely used in presses and pumping systems. Forged eccentric shafts manufactured by HDC Manufacturing exhibit strong fatigue resistance even under offset loads.
Forged Spline Shafts
Forged spline shafts find application in gearboxes and steering structures. By forging, precision machining, and surface hardening, HDC Manufacturing can meet your design tolerances and improve the wear resistance of key teeth.
Forged Crankshafts
Forged crankshafts play a key role in reciprocating machinery, including internal combustion engines and compressors.HDC Manufacturing forges complex custom crankshafts that withstand frequent, high-intensity cyclic loads.

FAQs
Do you supply standard forged shafts?
No, HDC Manufacturing is focusing on providing custom metal forging solutions to customers. Standard products are not supplied.
Which is better, cast or forged shafts?
Forged shafts are stronger and last longer in tough conditions. Cast shafts are cheaper and fine for stock applications. If the application involves high RPM, heavy loads, or high torque, forged is the better option.
What are the common applications for forged shafts?
Forged shafts are used in demanding applications like heavy machinery, automotive drivetrains, wind turbines, and industrial gearboxes—wherever high torque, heavy loads, and reliability matter most.
What is the typical lead time for a custom gear order?
Lead time depends on shaft type, size, and quantity. Small to medium batches typically ship within 4–6 weeks. We provide detailed lead time estimates with each quote.
Do you provide after-sales support?
Yes. We stand behind our quality. We provide comprehensive after-sales service, including rapid response to any quality discrepancies, ongoing technical support, and full traceability with our material and inspection reports.
Can you arrange door-to-door delivery?
Yes. We offer hassle-free global logistics. Besides EXW, FOB, and CIF, we provide DDP (door-to-door) shipping services via international express, air freight, or sea freight, tailored to your project timeline.
