prototype sheet metal parts
Custom Sheet Metal Prototyping
Functional sheet metal prototypes for design verification, assembly testing and pilot production.
Hongming Sheng supports low-volume and complex sheet metal parts with laser cutting, CNC bending, welding, hardware installation and finishing.
Our engineering team reviews the design, material and manufacturing route so the prototype can provide useful feedback before larger production.
Laser CuttingProfiles, holes, slots, cutouts and complex flat patterns.
CNC BendingFlanges, folds, covers and formed sheet metal structures.
WeldingTIG, MIG and suitable joining for prototype assemblies.
Hardware InstallationPEM nuts, studs, rivet nuts, hinges and specified fasteners.
Surface FinishingPowder coating, anodizing, brushing, plating and marking.
Assembly SupportMechanical fit checks and subassembly support where required.
What a Prototype Helps You Verify
Part dimensions, bend results and component fit
Connector openings, mounting holes and fastener positions
PCB, power supply and cable-routing clearance
Cover alignment, access panels and serviceability
Surface appearance, color and product presentation
Assembly sequence and possible production improvements

Engineering Support Before Production
Our engineers can review bend radii, hole locations, hardware, weld access, part clearance, surface finish and other details that may affect manufacturability or assembly.
For an accurate quotation: provide the latest drawing or model, material, thickness, quantity, finish, critical tolerances and target delivery requirements.
Confidential Prototype Development
Customer drawings, samples and technical information are treated as confidential project information. NDA support is available for OEM prototype projects.
