Product Selection Differences for Hammered and Upset Forgings

Hammered and upset forgings are two common methods used in metalworking to shape metal parts. Here are the key differences between the two processes:

  1. Method of Forming:

    • Hammered Forging: In hammered forging, the metal is shaped by applying repeated blows with a hammer or a mechanical forging press. This process is typically used for smaller parts or intricate shapes.
    • Upset Forging: Upset forging, also known as upsetting, involves compressing the length of a metal piece to increase its cross-sectional area while reducing its length. This process is often used for forming larger and simpler parts.

  2. Application and Complexity:

    • Hammered Forging: Hammered forging is more suitable for forming complex and detailed parts that require precision shaping.
    • Upset Forging: Upset forging is commonly employed to produce parts where a larger section of material is needed, such as in bolts, screws, and other fasteners.

  3. Material Properties:

    • Hammered Forging: Hammered forgings can help improve the grain structure of the metal, making it stronger and more durable.
    • Upset Forging: Upset forging can be utilized to increase the density and strength of the material in the forged area.

  4. Tooling and Equipment:

    • Hammered Forging: Hammered forging may require specialized hammers, dies, and presses to shape the metal effectively.
    • Upset Forging: Upset forging typically involves specialized dies and equipment designed to compress and shape the metal through axial force.

  5. Cost and Efficiency:

    • Hammered Forging: Hammered forging can be more labor-intensive and time-consuming, especially for crafting intricate designs.
    • Upset Forging: Upset forging may be more efficient for producing large volumes of simpler parts due to reduced shaping times.

When choosing between hammered and upset forgings, consider factors such as the complexity of the part, desired strength and density requirements, production volume, and cost-effectiveness to determine the most suitable forging method for your specific application.
