Material & thickness
Specify alloy or steel grade and nominal thickness.
← SANHE HomeSheet Metal FabricationSheet metal for enclosures,
Sheet metal for enclosures,
panels and mounting parts
Connect formed structures with the components they support. Review material, bends, joints, finish and assembly requirements together.
Panels, brackets and formed covers
Sheet-metal details have different jobs: creating access, securing components, guiding airflow or enclosing an assembly.
- 01
Panels and access openings
Define connector openings, ventilation slots, fixing holes and cosmetic surfaces together.
- 02
Mounting brackets
Check flange reach, bend access, hole position and clearance for fasteners.
- 03
Formed covers
Review seams, joining sequence and final shape before specifying the visible finish.
Connect the enclosure to the assembly
Rails, trays and mounting interfaces need to fit the parts they support.
Identify the assembly datum and fastener positions early. CNC parts and formed parts can then be reviewed against the same interface drawing, including coating allowance and grounding contacts.
Cutting to finished assembly
The supplied workshop information includes laser cutting, CNC punching, CNC bending, coating and assembly processes.
- 01
Cut and punch
Produce profiles, slots and hole patterns; deburr edges before downstream work.
- 02
Bend and form
Arrange bend order around tooling access and the finished assembly envelope.
- 03
Join and fasten
Select welding, riveted hardware or screws around loading, access and service needs.
- 04
Finish and assemble
Confirm powder coat or paint, masking, colour reference and protection of finished surfaces.
What to specify on a sheet-metal drawing
These details connect appearance, manufacturing and installation.
Bends & interfaces
Identify bend direction, internal radius and critical hole locations.
Visible surfaces
Mark cosmetic faces, colour samples, texture and protected contacts.
Final checks
Check overall size, interfaces, edge quality and final assembly fit.
PROJECT SCOPE
Define the complete requirement
Use the drawing and assembly context to set the manufacturing and supply scope.
01Formed edges
Bends, returns and access
02Joining features
Welds, inserts and fasteners
03Assembly interfaces
Panel openings and mating parts
- Material & blank
- Specify grade, thickness, grain or cosmetic direction and the released flat pattern.
- Bends & joints
- Review forming access, bend relationships, welds, inserts and assembly access.
- Mounting interfaces
- Match hole patterns, contact faces and the mating CNC components.
- Finish & inspection
- Agree visible faces, protected fits and the final assembly condition.
PROJECT STAGES
Move forward with a shared baseline
Approval points depend on the actual part and project scope.
- 01
Drawings & context
Released model/drawing, target material and expected quantity.
- 02
Engineering review
Process access, interfaces, appearance and open questions.
- 03
Sample / trial
Agree approval features and record any changes before the next quantity.
- 04
Release & delivery
Confirm the revision, acceptance records and protective packing.
ACCEPTANCE & DELIVERY
Review the finished assembly condition
Include dimensional references, appearance and the records needed at receiving.
- Functional features
- Identify locating/mating features, checking conditions and approval requirements.
- Appearance reference
- Specify visible faces, texture/colour references and permitted contact areas.
- Records & identification
- Agree part/tool identification, revision, quantity and delivery documentation.
PROJECT QUESTIONS
Before you send your files
You can discuss NDA requirements before technical files.
What should I send for a quotation?
Provide the model/drawing, material, quantity, application and critical interfaces. Add assembly references when the part joins other components.
Can I begin with a sample or incomplete drawing?
Yes. Explain the known dimensions, function and available files so the review can identify what still needs definition before manufacture.
How is the final supply scope agreed?
Agree the included operations or tool components, sample approvals, inspection and records in the project quotation and confirmed order.
