    | Product Description

    Rough-machined forgings are semi-finished components produced by forging processes and then subjected to preliminary machining. They feature superior strength, refined grain structure, and excellent mechanical properties. Compared with castings, forgings provide higher density, greater durability, and longer service life. These forgings are widely used in automotive components, mining machinery, construction equipment, oil & gas, energy, and heavy industries, serving as the solid foundation for subsequent precision machining.

They are ideal for manufacturing critical components that require high load capacity and long service life. With optimized forging and machining processes, they ensure structural integrity and strength for subsequent finishing operations.

    FAQ | Frequently Asked Questions

    Q1: Can you manufacture rough-machined forgings based on customer drawings?

    A1: Yes, we provide OEM/ODM services based on customer drawings and samples, meeting specific size, tolerance, and material requirements.

    Q2: What is the difference between forgings and castings?

    A2: Forgings have denser metal structures, superior mechanical properties, better fatigue and impact resistance, making them ideal for critical parts.

    Do rough-machined forgings undergo heat treatment?

    Yes, depending on requirements, heat treatments such as normalizing, quenching, and tempering can be applied to enhance strength and performance.
