Our Drop Forging Process
Raw Material Selection
We source high-quality metal billets or bars tailored to required mechanical properties and chemical composition.
01
Cutting and Heating
The material is cut to length and uniformly heated to forging temperature, ensuring plasticity and structural integrity.
02
Die Preparation
Precision-machined forging dies are prepared and aligned to ensure accurate shaping and repeatability for each forging cycle.
03
Drop Forging Operation
A heated billet is placed in the die, then repeatedly struck by a drop hammer or press to form the desired shape.
04
Trimming and Flash Removal
Excess material (flash) is trimmed from the forged part using a secondary die or trimming press.
05
Heat Treatment (Optional)
Parts may undergo quenching, tempering, or annealing to enhance strength, hardness, and fatigue resistance based on application.
06
Surface Cleaning
Forgings are cleaned using shot blasting or pickling to remove scale, improve appearance, and prepare for further processing.
07
Machining and Finishing
Critical dimensions are CNC machined, and additional finishing processes are applied for precision and surface quality.
08
Main Drop Forging Types
Closed Die Drop Forging
- Metal is compressed in shaped dies to form precise, near-net parts.
- Best for high-volume production needing tight tolerances and part consistency.
- Common in automotive, aerospace, and industries requiring complex, strong components.

Open Die Drop Forging
- Heated metal is shaped with repeated blows between flat or contoured dies.
- Ideal for large parts needing strength and controlled grain structure.
- More shape flexibility, but requires machining for final dimensions.
