ON-DEMAND METAL MANUFACTURING · OEM / ODM
Custom metal parts manufactured from your drawings, 3D files or approved samples

Hongming Sheng supports product developers, engineers and purchasing teams with sheet metal fabrication, metal stamping, CNC machining, welding, surface finishing and assembly.

From one-off CNC parts and prototypes to repeat production, we review the geometry, material, critical requirements, finish and quantity before proposing a suitable manufacturing route.

One Manufacturing Process

From Drawing Review to Delivery

1

RFQ Review

Confirm files, material, quantity, finish, critical features, application and delivery requirements.

2

DFM & Quotation

Evaluate a practical process route, tooling needs, secondary operations, inspection and cost drivers.

3

Prototype or Sample

Manufacture and check dimensions, fit, finish and agreed functional requirements before repeat production.

4

Production & Shipment

Produce against approved drawings and samples, complete specified inspection, finishing, packing and shipping preparation.

What to Include for an Effective Quotation

Technical Information

  • 2D drawing and 3D CAD file
  • Material grade and thickness
  • Critical tolerances and interfaces
  • Finish, color and cosmetic surfaces

Commercial Information

  • Prototype and production quantities
  • Target delivery date
  • Inspection and documentation needs
  • Packaging and destination requirements

Discuss Your Custom Metal Part

Send drawings or sample information directly by email for engineering review. If your files are not ready, use the inquiry form to leave contact information and basic project details first.
