Cold‑headed parts are primarily used to manufacture miniature precision fasteners, such as internal screws for mobile phones and interface pins, ensuring high strength and consistent quality. Stampings are widely applied in areas like PCB shielding covers, connector housings, and antenna spring contacts, enabling mass production of thin‑walled, complex‑shaped components. Machined parts are used for base‑station filter cavities, heat sinks, and high‑precision structural components, meeting stringent dimensional tolerances and surface finish requirements to guarantee signal stability and equipment reliability.
