4. Wide Material Compatibility:

• Suitable for almost all forgeable metals, including those for high-temperature or high-stress environments.

5. Extended Lifespan:

• High resistance to failure under heavy loads or extreme conditions.

Process Overview of Walkson Open-Die Forging:

An open die forging diagram illustrates the steps involved, helping engineers understand how the metal is shaped and formed.

1. Heating the Material:
The billet or ingot is heated to a malleable temperature in a furnace.

2. Positioning on the Die:
The workpiece is placed on a flat or simple die, and controlled hammering or pressing is applied.

3. Shaping the Metal:
Skilled operators manipulate the workpiece between hammer blows or press strokes to achieve the desired shape.

4. Cooling and Post-Processing:
After forging, the product is cooled and often undergoes heat treatment or machining to achieve final specifications.

Limitations of Walkson Open-Die Forging:

• Less Complex Shapes: Cannot produce intricate or detailed geometries without additional machining.

• Requires Skilled Operators: Precision depends on the expertise of the operator and the tools used.

• Material Waste: Some excess material may need to be removed during machining.

Summary:

Walkson Open-die forging products are large, durable components with excellent mechanical properties, widely used in industries requiring strength and reliability. This process is ideal for creating custom parts, particularly for heavy-duty applications in heavy machinery, power generation, oil & gas, and marine industries.
