CUSTOM SHEET METAL PARTS · CHINA OEM MANUFACTURING
One supplier for sheet metal parts, enclosures and complete assemblies

Hongming Sheng manufactures custom sheet metal components from customer drawings, 3D files or approved samples. We support prototypes, low-volume builds and repeat production for equipment manufacturers and OEM projects.

Our engineers review material, thickness, tolerances, bends, welds, hardware, finish and assembly requirements before establishing the manufacturing route.

Engineering and Quality Support

Design Review

  • Material grade, thickness and availability
  • Bend radius, flange size and hole-to-bend distance
  • Weld access, assembly sequence and distortion risk
  • Hardware, connector openings and service access
  • Finish buildup, masking and cosmetic surfaces

Inspection Planning

  • Critical dimensions and drawing datums
  • Hole patterns, bend angles and assembly fit
  • Threads, installed hardware and mating features
  • Weld location and agreed appearance criteria
  • Surface color, texture and packaging requirements
“One-stop” does not mean one process fits every part. A laser-cut prototype, a repeat-production stamped part and a welded enclosure may require different tooling, fixtures and inspection plans. The route should be selected around geometry, volume and application.

Example: Stainless Steel Equipment Bracket

Drawing Review → Cutting → Forming → Finish → Inspection

For a brushed stainless steel bracket, the team first confirms material grade, thickness, grain direction, bend radius, critical dimensions and cosmetic face.

The blank is laser cut, formed with suitable tooling, deburred and brushed in the specified direction. Hole positions, bend angles, overall size and visible surfaces are then checked against the approved drawing.

Actual tolerances and inspection methods depend on the part geometry and must be agreed during quotation.
