Rolled Press Forging is a metalworking technique where a heated metal billet is shaped by a combination of rolling forces between rotating rolls and compressive pressure from a press, essentially combining the shaping aspects of both rolling and press forging to achieve a desired form, often used to create seamless rings with precise dimensions and improved grain structure.
The most common application is for producing seamless metal rings, where a cylindrical billet is first pierced to create a donut shape, then further shaped by the combined rolling and pressing forces.
Benefits of rolled press forged parts:
Improved grain flow: The combined rolling and pressing action results in a more uniform and aligned grain structure, enhancing the mechanical properties of the final product.
High dimensional accuracy: This process allows for precise control over the ring's dimensions and tolerances.
Reduced material waste: By utilizing the entire billet, material waste is minimized.
