Custom Forging Service for Gear Manufacturing
Backed by advanced forging and CNC technology, HDC offers one-stop solutions for custom-built gears. From forged gear blanks to precision finished gears, we forge them exactly for your project
Gears We Manufacture
With comprehensive manufacturing capabilities, we support your unique design with precision and reliability.
Gear Blanks
If you have manufacturing capabilities to cut teeth and finish the gear, or need to specify a machining manufacturer, HDC can provide mass gear blanks at a competitive price.
Cylindrical Gears
Cylindrical is the most common gear shape. HDC can fabricate it with a spur tooth or a helical tooth for various of industrial applications, such as the transmission box in a car.
Bevel Gears
Bevel gear is widely used in the differential and steering mechanisms. By forging, we enable near-net shape forming, resulting in better production efficiency and tooth root strength.
Face Gears
For engineers who are chasing a compact layout and high load capacity, a face gear is definitely the right answer. By forging, we further enhance its properties in high-end applications.
Worm Gears
HDC primarily supplies unprocessed worm gear blanks. If you require, we can also finish it according to your design.
Benefits of Forged Gears
Why forge gears instead of casting and machining? Here are the answers.
Better Gear Tooth Strength
Through close-die forging, you can get a stronger tooth root structure created by controlled grain flow.
Longer Serving Life
Forging produces a dense, uniform microstructure, helping your gears last longer under repeated cyclic loads.
Minimal Waste & Cost Effective
Close-die forging produces gear blanks very close to the final shape, which requires less machining and leads to cost-effectiveness.
High Consistency
Forging with a precision-machined die, we produce gear blanks with consistent and predictable quality.
HDC Core Capabilities
HDC controls all the manufacturing processes for stable and consistent quality.
Forging
We utilize close-die forging to produce gear blanks with optimized strength, setting a solid foundation for the gear you require.
Heat Treatment
We apply heat treatment in-house, ensuring that every batch of gears reaches the mechanical properties in your design.
Machining
Combined with CNC machining, we finish your gear with accurate geometry and tolerances, ensuring it is ready for real applications.
Quality Control
We utilize CMM, gear profile testers, and hardness testers to ensure every gear meets ISO/DIN standards before shipping.

Materials for Forged Gears
We work with a wide range of materials for your custom forged gear project.
For gear used in agricultural machinery and general industrial equipment that has moderate performance requirements, we recommend carbon steel due to its excellent formability and lower cost. Carbon steel grades we offer include: 1045, C45, etc.
Surface & Heat Treatments Options
For customers who need finished gears that are ready to use, we offer comprehensive surface and heat treatment options for you to choose from. Which including:
- Quenching & Tempering
- Hardening
- Bead Blasting
- Coating
- Polishing
We apply surface & heat treatments based on your requirements and the metal used to achieve desired results.

FAQ
Why should I choose forged gears over fully machined ones?
In short, forging is a mature process for the mass production of gears. Usually, it needs to be combined with CNC machining, that is, forging for the blank and CNC finishing the details.
Full CNC-machined gears are not practical in real applications; in most situations, it’s used for prototype and functional validation.
Do you provide finished gears or just blanks?
Both. We supply forged gear blanks for customers with their own machining, and fully finished gears with CNC precision, heat treatment, and surface treatment as needed.
Do you provide heat treatment reports and material certifications?
Yes, heat treatment reports and material certifications are available upon request.
Can you reverse engineer from a sample?
Of course, send us the sample, we will scan it, create the CAD drawing, and manufacture a perfect replacement.
What is the typical lead time for a custom gear order?
Lead time depends on gear type, size, and quantity. Small to medium batches typically ship within 3–6 weeks. We provide detailed lead time estimates with each quote.
Can HDC support international shipments?
Absolutely. We export forged gears globally, including Europe, North America, and Asia. Logistics and packaging are handled professionally to ensure safe delivery.
