Our Drop Forging Process

Material Selection

The process begins with selecting the appropriate material, typically billets or bars. The choice of material affects the mechanical properties and performance of the final component. 

Heating the Material

The selected material is heated to a specific temperature, usually between 1,500 and 2,200°F. Heating improves flexibility, allowing the material to deform more easily during forging. 

Forming the Workpiece

The heated material is placed in a die set of two halves. A high-velocity hammer or press strikes the material, forcing it to fill the die cavity and achieve the desired shape. 

Cooling and Removal

Once the forging operation is complete, the component is allowed to cool before being removed from the die. This cooling process can also involve controlled methods to ensure the material retains its desired properties. 

Trimming and Finishing

After removal, excess material, such as flash or unwanted features, is trimmed off. Additional finishing processes like machining or surface treatment may be applied to achieve tight tolerances and specific surface finishes. 

Quality Control

The final components undergo rigorous quality checks to ensure they meet specified standards. This may include dimensional inspections, mechanical property testing, and non-destructive evaluations to verify integrity and performance. 

Drop Forging Materials

Drop forging utilizes high-strength metals to produce durable components with excellent integrity. This process minimizes defects and enhances performance, meeting rigorous industry standards.

How does the temperature of the metal affect the drop forging process?

The temperature significantly influences the flexibility of the metal. Heating the metal reduces its yield strength, making it easier to deform and fill the die cavity, ensuring precise shaping without cracking. 

What role does die design play in drop forging efficiency?

Die design is crucial for achieving optimal material flow and minimizing waste. Properly designed dies to facilitate uniform deformation, reduce the need for secondary machining, and ensure tight tolerances in the finished components. 

How is material flow controlled during the drop forging process?

Adjusting the strike force and die geometry controls the material flow. Accurate control of these parameters ensures that the material fills the die, minimizing defects and enhancing mechanical properties. 

What are the typical post-forging treatments applied to drop-forged components?

Post-forging treatments may include heat treatment, surface hardening, and machining. These processes improve the mechanical properties, such as tensile strength and fatigue resistance, while achieving the required surface finish.
