Manufacturing Processes

Forging
Metal billets are plastically deformed under high pressure using forging equipment to produce parts with superior mechanical strength, precise shape, and reliable dimensional stability.

Precision Casting
Molten metal is poured into molds through controlled casting processes, including both sand casting and specialized casting methods, to produce complex parts with consistent quality and performance.

Precision Machining
Components are machined with high accuracy based on detailed technical drawings, ensuring strict adherence to OEM specifications.

Surface Treatment
Components undergo precision heat treatment processes to achieve optimal hardness and wear resistance for heavy-duty applications. Core processes include annealing, normalizing, quenching, tempering, hardening & tempering, aging treatment, carburizing, and nitriding to enhance material properties and extend component service life.
