Open Die Forging, also known as  "Hand Forging" or "Forged Block", is a versatile and cost-effective metal forming process that utilizes flat dies to shape metal without the need for complex tooling. This method is particularly advantageous for producing large, custom, or low-volume components in various industries.

In open die forging, metal billets are heated and then deformed between flat or simple dies through repeated hammering or pressing. The dies do not fully enclose the material, allowing for lateral movement and the creation of custom shapes. This process is ideal for producing parts that require specific grain orientations or larger sizes that closed die forging cannot accommodate .

Advantages of Open Die Forging

• Enhanced Material Properties: The forging process refines the grain structure, resulting in improved fatigue resistance, increased strength, and a finer grain size .

• Continuous Grain Flow: Open die forging maintains continuous grain flow, which enhances the mechanical properties of the forged components.

• Reduced Voids and Porosity: The process minimizes the chance of internal voids or porosity, ensuring high internal quality.

• Cost-Effectiveness: Without the need for complex tooling, open die forging offers a more economical solution for low to medium production volumes.

• Flexibility in Design: It allows for the production of custom shapes and sizes, accommodating unique design requirements.
