Description
Rolled and punched metal parts are precision-engineered components designed for structural support, mounting, and enclosure applications in industrial and electronic equipment. These parts are manufactured through a combination of metal rolling and punching processes, ensuring accurate cylindrical or curved shapes together with consistent hole positioning.
The rolling process forms flat metal sheets into round or semi-round profiles with uniform diameters and smooth curvature, providing excellent dimensional stability and mechanical strength. Punching operations are then applied to create mounting holes, ventilation openings, or functional cutouts with high repeatability and clean edges.
A wide range of materials can be processed, including stainless steel, aluminum, and carbon steel, allowing the parts to meet different strength, weight, and corrosion resistance requirements. Various surface treatments such as zinc plating, powder coating, anodizing, or polishing can be applied to improve durability, appearance, and environmental resistance.
Rolled and punched metal components are commonly used in equipment housings, brackets, protective covers, and mounting structures. Custom dimensions, hole patterns, and finishing options are available to support OEM and ODM projects with stable quality and scalable production.
