01 / DFM REVIEW
From customer drawings to a build plan.
Review the customer drawing package, identify manufacturing risks and agree on practical design actions before sampling and production.
01 / Receive & Align
Check 2D drawing and 3D CAD revisions, assembly interfaces, target quantities and finish requirements. Confirm missing information and flag critical dimensions.
02 / Assess Requirements & Define Actions
| Customer requirement | DFM assessment | Review output |
|---|---|---|
| Application category · Consumer electronics | Clarify use conditions, appearance expectations, access and ventilation needs. | Agreed functional and cosmetic criteria. |
| Component scope · Enclosures, panels & internal mounts | Review wall sections, cutouts, hole spacing, fastener access and assembly clearances. | Marked-up geometry and interface actions. |
| Material · Zinc alloy | Confirm alloy grade and stock form; assess process suitability, wall thickness and tooling access. | Proposed manufacturing route and material queries. |
| Surface treatment · Powder coating (baked finish) | Review surface preparation, color, texture, coating build, curing and masking of mating surfaces. | Finish specification and masking plan. |
| Finish function · Corrosion protection | Confirm exposure conditions; agree on pretreatment, coverage and any required corrosion testing. | Coating acceptance criteria and agreed test scope. |
| Dimensional tolerance · ±0.3 mm | Check tolerance applicability, datums, stack-up and coating allowance; define the inspection stage. | Critical-dimension list and inspection plan. |
03 / Feedback, Customer Confirmation & Release
Return a marked-up drawing and DFM action list with proposed changes and open questions. Resolve actions with the customer, confirm the drawing revision and release the agreed package for prototyping.
DFM handover: reviewed drawings + action log + material / finish requirements + inspection plan. Sample approval precedes production release.
02 / FROM PHOTOGRAPH TO STRUCTURE
A closer look at the enclosure.
Open-front mounting chassis: simplified views based on the supplied image.
CONCEPT DRAWING / NOT TO SCALE / NO DIMENSIONS
Reconstructed from the customer photograph. Hidden geometry, thickness and radii are simplified. For visual review only; production requires approved CAD and drawings.
03 / DESIGN TO DELIVERY
From an approved concept to finished components.
01 / Design & DFM
Review CAD, interfaces, alloy grade and manufacturing feasibility.
02 / Prototype & approve
Check sample fit and finish; approve drawings and coating requirements.
03 / Produce components
Follow the approved process; check geometry, openings and assembly fit.
04 / Prepare & powder-coat
Prepare surfaces, mask interfaces, apply powder and cure to specification.
05 / Inspect & release
Verify ±0.3 mm requirements, coating appearance and agreed quality criteria.
06 / Pack & deliver
Protect finished surfaces, label parts and arrange shipment with records.
Bending machining
Bending and forming form part of the component production route before coating and assembly.
