- Ensure proper forging and heat treatment to avoid defects like cracks or uneven hardness.
- Perform non-destructive testing (e.g., ultrasonic or magnetic particle inspection) to ensure quality.
- Optimize gear design for load distribution and efficiency.
42CrMo4 forged gears shaft can deliver reliable performance in gear motor applications.

Drop forging is a highly valued metal forging process that uses a pair of impression dies and a heavy hammer to form and compress metal bars or billets into complex shapes. The steel forging parts are with high density, good mechanical properties and wear resistance, compared with casting components.
Baoding Guokun’s drop forging process
| Close die forging or mold forging process | |
| Material Selection | Choose the appropriate metal (e.g., carbon steel, alloy steel, aluminum, or titanium) based on the component’s requirements. Ensure the required steel meets the required chemical composition and quality standards. Baoding Guokun will test the material’s chemical composition before storage. |
| Billet Preparation | Cut the raw material into billets of the required size. And heat the billet to the forging temperature (typically 1100°C–1200°C for steel) to make it malleable |
| Die design and preparation | Design the dies (upper and lower) to match the final shape of the component. Dies are typically made from high-strength tool steel and are precision-machined. |
| Forging | Place the heated billet into the lower die. Apply pressure using a hydraulic or mechanical press to force the metal into the die cavity. The metal fills the die, taking the shape of the mold |
| Flash Formation & Trimming | Excess metal, called flash, flows out of the die cavity through small gaps. Remove the flash and excess material using trimming dies or machining |
| Cooling | Allow the forged part to cool slowly (for some materials) or control the cooling rate to achieve desired properties. |
| Heat Treatment | Perform heat treatment processes like normalizing, quenching, and tempering to enhance mechanical properties (e.g., hardness, toughness) |
| Finishing | Machine the forged part to achieve precise dimensions and surface finish. Apply surface treatments (e.g., sand blasting, coating) if required |
