Flat profiles
Review outlines, holes, edge condition and important distances. Define the exact stock and any later forming or surface requirements.
PARTNER-SUPPORTED MANUFACTURING / SHEET PARTS
Sheet metal fabrication. Define the final shape and the route between operations.
A flat cut profile, formed bracket and fabricated assembly need different manufacturing and acceptance questions. Connect stock, bends, joints and finish to the delivered interface before comparing offers.
KeepWin coordinates partner-supported review. Exact material, responsible operations, process availability, dimensions, inspection, commercial quantities and timing are confirmed in the project proposal; no universal capability or certification is promised.
Generated sheet-part geometry reference. It does not establish sheet grade, thickness, measured dimensions or actual fabrication capacity.

RouteCutting, forming and assembly
AcceptFinal geometry and evidence
01 / ROUTE SELECTION
Choose the operation chain around the finished part.
Begin with function and geometry rather than selecting a cutting label alone. Subsequent forming, joining or coating may define the actual accepted state.
Formed parts
Identify flanges, bend relationships and mating interfaces. Review tool access, sequence and final-state dimensions for the actual material.
Fabricated assemblies
Provide component definitions and joining intent. Agree locating, fit, finish and responsibility for the assembled result.
02 / DESIGN INPUTS
Show which relationships matter after forming or joining.
A flat pattern and a finished drawing answer different questions. State the controlling definition and ask for the route assumptions to be reviewed.
Controlled geometry
Send units, revision and whether flat or formed geometry governs. Resolve file conflicts before preparation instead of assuming the flat pattern is final.
Features and bends
Mark holes, notches, reliefs and nearby bends. Review interference and distortion questions for the offered stock and tooling.
Assembly intent
Show mating components, datums and joint purpose. Ask how the operation chain preserves critical relationships.
Protected surfaces
Map visible, contact, electrical or sealing-related faces. Confirm permitted marks and any protection needed through processing.
03 / STOCK & FINISH
Specify the delivered material and surface condition.
Alloy family, thickness and finish affect the operation plan. A generic metal description does not control every stock or treatment requirement.
| Decision | Provide | Confirm |
|---|---|---|
| Stock | Exact grade, thickness and supplied condition. | Offered supply and permitted alternatives. |
| Formed state | Bends, datums and critical interfaces. | Tooling approach and final-state checks. |
| Joining | Component map and joint purpose. | Available method and responsible operations. |
| Finish | Surface reference and protected areas. | Compatible process and dimensional effects. |
04 / OPERATION HANDOFF
Keep cutting, bending, joining and finish responsibilities visible.
Different operations may be performed through a partner route. The proposal should explain scope and the conditions passed between them.
Supplied sheet-cutting equipment reference. It does not identify the machine used for every project or establish universal material and thickness capability.
Edge completion
State relevant burr, sharp-edge and surface limits. Confirm any deburring or refinement included after cutting.
Forming sequence
Review access and critical feature relationships after bends. Proposed radius or relief changes need approval where they alter function.
Assembly and coating
Define which work precedes the final acceptance. A fit checked before joining or coating may not represent the delivery.
Identity and changes
Connect stock, files and variants to records where required. Review material or sequence changes against earlier sample evidence.
05 / ACCEPTANCE
Inspect the finished condition the assembly needs.
Dimensions, edge condition, appearance and material identity are distinct evidence scopes. Agree methods and quantities for the actual delivery.
| Area | Define | Record |
|---|---|---|
| Geometry | Final datums, bend relationships and fits. | Method, sample scope and revision. |
| Edges | Functional edge and burr requirements. | Completed operation and accepted reference. |
| Appearance | Visible faces, texture/color and viewing basis. | Physical sample and finish state. |
| Material | Grade and requested supply evidence. | Identity and applicable record scope. |
06 / QUOTE PREPARATION
Compare complete fabrication offers.
A cut blank and a finished assembly are different deliverables. Make secondary operations, evidence and transport assumptions visible.
Part brief
Send controlled files, material/thickness, quantities, variants, destination and target milestones. Include joint purpose and important final interfaces.
Commercial scope
Identify preparation, cutting, forming, joining, finishing, sample work, inspection, records and packing where relevant.
Approval basis
Agree sample purpose, change owner and final-state criteria. Exact capacities, MOQ, available records and timing require proposal confirmation.
07 / QUESTIONS
Before a sheet-fabrication enquiry.
The final shape, stock and surface state belong in one brief.
Is a flat pattern enough?
Provide the formed or assembled requirement and state file precedence. A flat profile may not explain datums, final fit, joints or finish intent.
What thicknesses and sizes are available?
These depend on material, geometry, operations and the responsible route. No universal numerical range is published.
Are deburring and finish included?
Only the agreed work should be assumed. State edge condition, visible faces, protected areas and final acceptance.
Can the bend radius change?
Review its effect on shape, interfaces and later work before approving a proposed change.
Are all processes performed in-house?
This is partner-supported review. Responsible operations and actual site scope are confirmed for the proposal.
PREPARE THE NEXT DECISION
Send the formed requirement and the stock specification.
Include CAD and drawing, units and revision, material and thickness, bends and joining needs, critical interfaces, surface map, quantities and destination.
