Hongming Sheng provides OEM metal fabrication and custom welding services based on customer drawings, CAD files and engineering specifications.

We combine welding with laser cutting, CNC bending, machining, tube fabrication, hardware installation and final assembly for built-to-print metal components and structures.

Built-to-Print OEM Fabrication

Parts are manufactured according to customer drawings and specified dimensions, materials, welding details and surface finishes.

• 2D drawing and 3D CAD-based manufacturing
• Custom brackets and structural parts
• Sheet metal enclosures and housings
• Tube and profile structures
• Welded frames and support assemblies
• Mechanical subassemblies

Welding Processes

• TIG welding
• MIG welding
• Spot welding when applicable
• Robotic welding for suitable repeat parts
• Fixture-assisted welding
• Weld grinding and finishing

Sheet, Tube & Structural Fabrication

Different OEM projects may combine sheet metal, tube and structural profiles into one finished fabricated assembly.
