Mounting plates
- Key requirements
- Hole patterns and datum locations
- Verification to agree
- Dimensional inspection against the approved drawing; record critical hole positions.
- Supply scope
- Flat sheet-metal components
Drawing-based manufacturing
Precision Metal Stamping
Review material, sheet thickness, formed geometry and inspection requirements together. Start with the drawing and the features that must fit.
Engineering geometry
Blank geometry & formed interfaces
Blank + bend + mounting holes
The flat blank and formed angle share mounting holes, but the bend changes the relationship between the mating faces. Dimension the final formed condition as well as the flat pattern.
For a mounting bracket, identify bend direction, hole position, edge condition and the surfaces that contact the assembly. Review the specified sheet material and finish with those interfaces.
Process selection
Plates, brackets & finished components
Use the drawing to identify each part’s mating features and acceptance criteria.
Flat plates and formed brackets connect components through a small number of critical features. Ningbo Empire coordinates the drawing review, forming route and downstream work through its strategic metal-manufacturing bases.
Formed brackets
- Key requirements
- Bend position, flange angle and mating faces
- Verification to agree
- Review the formed part, not only the flat pattern; inspect the assembly interfaces.
- Supply scope
- L-shaped and U-shaped brackets
Finished components
- Key requirements
- Edges, coating and protected contact areas
- Verification to agree
- Agree edge condition, finish inspection and packing with sample approval.
- Supply scope
- Project-defined finishing and repeat supply
Material ranges, thicknesses, tolerances and the manufacturing location are confirmed during project review. No universal stamping capability or qualification is implied.
Verification & production
Spring features & mating parts
Tooling and sample approval follow the formed-part drawing and specified sheet thickness.
- Locate: datum faces, hole positions and mating surfaces.
- Form: bend position, flange angle and springback acceptance.
- Finish: burr direction, edge condition and protected contact areas.
Inputs for This Manufacturing Route
- Material grade, sheet thickness, blank and formed geometry
- Burr direction, edge/hole tolerance, bends and mating interfaces
- Tooling, surface treatment, sample quantity and inspection plan
Verification & production
Progressive forming route
Material, forming sequence, tooling and downstream work are reviewed against the drawing and agreed sample.
Drawing & material
Confirm drawing revision, material specification, sheet thickness and critical interfaces.
Blank & form
Review blank geometry, holes, bend sequence and the effect of formed features on fit.
Tooling & samples
Agree tooling responsibilities, sample requirements and the approval route.
Inspect & supply
Define critical features, inspection records, packaging and repeat-order needs.
