Front panels located indicators and carried equipment identification with a consistent cosmetic finish.
The customer’s challenge
Markings wore away, indicator brightness was uneven and inaccurate holes impaired panel installation.
Material and fabrication route
2.0 mm aluminum; 1.0 mm steel.
Process route: Laser cutting → bending → anodizing / powder coating → printing / laser marking → window assembly → inspection.
Manufacturing changes
Paint-filled engraving, a light-guide arrangement, tighter hole control and coordinated finishing addressed the issues.
Engineering analysis
The front panel combined mechanical location, visual consistency and durable identification. A correctly sized opening would not solve uneven indicator appearance or markings that wore away. The project therefore coordinated the finish, light-guide arrangement and marking method with the hole pattern. The wipe-cycle result applies to the tested marking system; replacement artwork and finish changes should remain revision-controlled.
Inspection and project results
Markings withstood the reported wipe test, indicators appeared uniform and the panels fitted consistently.
| Project measurement or production detail | Recorded value |
|---|---|
| Marking wipe test | ≥500 cycles |
| Hole-position tolerance | ±0.05 mm |
| Approximate 1U panel | 482 × 44 mm |
| Visual inspection | 100% |
These figures describe the project configuration and production scope above. Dimensional, material and production details are identified separately from performance tests. For a new order, the inspection method and acceptance criteria should be agreed against the released drawings.
Planning a similar OEM component
A useful RFQ for this application should make the following interfaces and acceptance requirements clear:
- Indicator and connector layout.
- Approved artwork and marking method.
- Cosmetic reference and finish.
- Wipe-test and hole-position acceptance.
Include the current drawing revision, mating-component information, quantities and required delivery sequence. Identifying unresolved requirements at quotation stage helps distinguish fabrication work from the equipment-level checks that the project needs.
