berita perusahaan tentang What is Free Forging?

Free forging, also known as open-die forging, is a metalworking process that shapes metal without the use of a die to confine the workpiece. Instead, the metal is deformed between two simple, flat or shaped dies, allowing it to move and expand in all directions. This method is one of the oldest and most fundamental forging techniques, dating back to ancient times.

The process typically begins with a heated metal ingot or billet, which is then placed on a lower die. An upper die, attached to a hammer or press, then strikes or presses the metal. Operators use manipulators or cranes to control the workpiece, turning it and moving it between blows to achieve the desired shape. This flexibility allows for the creation of unique, large, or complex shapes that would be impossible to produce with closed-die forging.

• Production of Large Components: It is the ideal method for creating massive parts, such as shafts, rings, and discs, for industries like power generation, shipbuilding, and aerospace.

• Improved Material Properties: The intense hammering or pressing refines the metal's internal grain structure, eliminating porosity and improving its mechanical properties like strength, ductility, and fatigue resistance.

• Cost-Effectiveness for Small Batches: Since it doesn't require expensive, custom-machined dies, free forging is a cost-effective choice for producing a small number of specialized or prototype parts.

• Flexibility in Shaping: The process allows for greater design flexibility, enabling the creation of unique geometries and complex cross-sections that are difficult to achieve with other forging methods.

In summary, free forging is a critical manufacturing process that combines ancient craftsmanship with modern technology. Its ability to create large, high-strength metal components with superior properties makes it an indispensable technique in a wide range of heavy industries.
