Custom Sheet Metal Fabrication
Laser cutting, bending, welding, hardware insertion, and finishing for custom enclosures, panels, and brackets.
- Laser cutting and punching
- Press brake bending
- Welding, riveting, and PEM insertion
- Powder coating and marking
Service overview
Cutting, bending, joining, hardware, and finishing in one plan.
Kewei supports custom sheet metal enclosures, chassis, panels, brackets, covers, and welded assemblies. The route can combine laser cutting or punching, press brake bending, welding, riveting, PEM hardware insertion, grinding, surface finishing, marking, and simple assembly.
A fabrication review connects flat-pattern geometry with material thickness, bend direction, inside radius, tooling access, hole-to-bend distance, weld distortion, visible surfaces, hardware, and final assembly fit.
Representative folded enclosures, chassis, brackets, and panels with realistic sheet construction.
Key capabilities
Process planning connected to the drawing and end use.
The manufacturing route is reviewed around geometry, material behavior, critical features, appearance, inspection, and downstream assembly.

Materials
Material options linked to technical guidance.
Surface Finishes
Surface Finishes reviewed for material and application fit.
Tolerances and design guidance
Define what is functionally critical.
Sheet metal dimensions are affected by material thickness, bend radius, bend sequence, springback, welding heat, hardware insertion, and coating. Drawings should distinguish formed dimensions, flat-pattern references, and final assembly requirements.
DG 01
Keep holes, slots, and hardware clear of bend deformation zones.
DG 02
Use practical inside bend radii for the selected material and thickness.
DG 03
Define weld locations, weld type, grinding, and appearance expectations.
DG 04
Account for coating thickness at hinges, inserts, grounding points, and close-fitting assemblies.
Quality assurance
Inspection planning starts with the drawing.
Inspection points are selected from the controlled drawing, functional risk, process behavior, appearance criteria, and documentation requested for the project.

Manufacturing workflow
A controlled route from RFQ to shipment.
The exact route changes with process and project risk, but each stage keeps the approved drawings and requirements in view.

Sheet Metal questions from engineering and sourcing teams.
What should I provide for a sheet metal fabrication quotation?
Send a 3D CAD file when available, a 2D drawing for critical dimensions and tolerances, material, quantity, finish, inspection, and delivery requirements. An engineer reviews the package before quotation.
Can one project include cutting, bending, welding, and coating?
Yes. These operations can be reviewed as one route together with hardware insertion, marking, simple assembly, inspection, and packaging.
Should I provide a flat pattern?
A controlled 3D model and finished-part drawing are preferred. A flat pattern can help, but the fabrication team should still verify bend allowance, material thickness, bend radius, and formed dimensions.
How is lead time determined?
Lead time depends on geometry, material availability, quantity, tooling or setup requirements, surface finishing, inspection, and delivery needs. Timing is reviewed with the quotation rather than presented as a fixed promise.
