Customized Sheet Metal Prototype Manufacturing in China

Looking to turn your concept into a precise metal product? At Hongmingsheng, we specialize in customized sheet metal prototypes that help you validate and refine designs before mass production. One-stop fabrication with tight tolerances and fast lead times.

Why Partner With Us?

● Rapid prototyping: lead times as short as 3–5 working days ● Full engineering support: DFM, CAD files, and optimization ● Diverse materials: stainless steel, aluminum, carbon steel, and more ● High precision: CNC cutting, bending, and forming with tight tolerances ● Surface finishes: powder coat, anodize, plating, polishing, silk screen

From Idea to Execution

Start with your sketch or CAD. We create engineering drawings and 3D models, run manufacturability checks, and produce working prototypes via sheet metal fabrication, cutting, and bending.

● Laser cutting: ±0.15 mm precision, full CAD/CAM workflow ● Waterjet: no heat-affected zone, material integrity preserved ● Plasma: fast and efficient on thicker materials ● Flame: economical for high-thickness carbon steels

Sheet Metal Bending – Key Design Tips

We ensure precise bends with proper radii, clearances, and part orientation. Guidance for slots, hems, curls, and notches helps prevent deformation and speeds assembly.

Welding Capabilities

● 5 CNC robotic welding stations with seam tracking ● MIG, TIG, stick, and pipe welding for Al/SS/CS ● Certified welders with full weld inspection

Post-Processing & Secondary Services

● Heat treatment for enhanced mechanical properties ● Finishes: powder coat, anodize, galvanize, polish, paint ● Assembly and packaging per your specifications
