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 prototype manufacturing to help global clients validate and refine their designs before mass production. Whether you're in the early R&D phase or ready for small-batch manufacturing, our team offers one-stop fabrication support—designed to meet tight tolerances and fast lead times.

Why Partner With Us?

• Rapid Prototyping: Lead times as short as 3–5 working days
• Full Engineering Support: We assist with DfM, CAD drawings, and optimization
• Diverse Material Selection: Stainless steel, aluminum, carbon steel, and more
• High Precision: Tight tolerances with CNC cutting, bending, and forming
• Surface Finishes: Powder coating, anodizing, plating, polishing, and silk screen

From Idea to Execution

Our process begins with your idea or sketch. We help develop engineering drawings and 3D models, perform manufacturability analysis, and produce working prototypes using processes like sheet metal fabrication, cutting, and bending.

Sheet Metal Cutting Techniques

• Laser Cutting: ±0.15mm precision with full CAD/CAM integration
• Waterjet Cutting: No heat-affected zone, maintains material integrity
• Plasma Cutting: Fast and efficient for thicker materials
• Flame Cutting: For high-thickness carbon steels

Sheet Metal Bending – Key Design Tips

Our expert engineers ensure high-precision bends through proper design clearances, bend radii, and part orientation. We also offer guidance for slots, hems, curls, and notches to prevent deformation.

Welding Capabilities

• 5 CNC robotic welding stations with seam tracking
• Support for aluminum, stainless steel, and carbon steel
• Certified welders and full welding inspection
• MIG, TIG, stick welding, and pipe welding options

Post-Processing & Secondary Services

• Heat treatment to enhance mechanical properties
• Powder coating, anodizing, galvanizing, polishing, and painting
• Assembly and packaging per custom specifications
