Product Features

Custom Automotive Sheet Metal Parts

Designed for automotive structural and assembly applications, we manufacture brackets, connecting plates, mounting plates, fasteners, and other non-standard metal components based on your technical drawings—tailored to meet specific structural design and assembly requirements.

Complex Sheet Metal Fabrication

For components featuring multiple bends, numerous holes, irregular contours, or multi-part assemblies, we evaluate the optimal manufacturing process based on your drawings—ensuring strict adherence to dimensional specifications, structural integrity, and assembly feasibility.

Aluminum Polishing and Surface Treatment

We assess and apply appropriate surface treatments—such as polishing or brushing—based on the product’s aesthetic and functional requirements. The specific process is determined by factors including the aluminum alloy grade, material temper, part geometry, and required surface finish standards.

Scope of Application

- Automotive Components: Mounting brackets, retaining clips, connectors, sheet metal covers, and auxiliary structural parts.

- Complex Structural Assemblies: Multi-bend sheet metal parts, custom-shaped panels, components with multiple mounting holes, and modular metal structures.

- Aluminum Aesthetic/Visible Parts: Aluminum alloy panels, decorative panels, equipment covers, and parts requiring polishing or brushed finishes.

- Industrial Equipment: Equipment enclosures, control panel faces, mounting base plates, mechanical brackets, and protective structures.

- Electronics and Automation Equipment: Equipment frame accessories, mounting plates, connecting plates, and precision sheet metal assemblies.

For specific automotive-related parts, the intended use shall be determined by the customer’s design, material specifications, and applicable industry requirements.
