Le defi

"The main challenge was to deliver precision CNC parts while controlling anodizing color against approved sample coupons, agreed lighting conditions, and facultatif colorimeter checks."

Key Requirements

  • Precision CNC: Tight dimensional control for multi-face assembly.
  • Color Consistency: Anodizing had to be checked against approved sample coupons under agreed lighting and viewing conditions.
  • Surface Finish: Sanded smooth with sandpaper to prepare for optimal color absorption and premium look.

Our Execution

We implemented a strict quality control loop for manufacturing and surface finishing.

Advanced Machining

Combines 3 and 4 axis CNC machining, EDM, and laser marking to achieve the demand of air tight sealing and ensure proper multi-face assembly.

Color Matching Process

We naturally use RAL or Pantone color codes. We produce a sample coupon first, adjust the dye formulation, and only once it passes the colorimeter test, apply the same parameters for the ready parts.

Final Verification

Parts are checked against the approved master sample and color target, with colorimeter readings used when the acceptance criteria are agreed during RFQ.

Evidence basis

Ingenierie evidence record

Color anodizing evidence record. This public case summary is based on anonymized RFQ notes, engineering review, inspection planning, and packing handoff records; customer-sensitive details removed.

Last reviewed: 2026-07-01
Customer industry
Consumer / device hardware prototype; customer-sensitive details removed.
Part use
CNC aluminum appearance parts where dimensional fit and cosmetic color consistency both mattered.
Quantity
Prototype and low-volume review batch; final quantity was confirmed after sample approval.
Material
Aluminum alloy confirmed before machining and anodizing route selection.
Process
3/4-axis CNC machining, deburring, surface preparation, sample coupon review, and color anodizing.
Critical dimensions / tolerances
Mating edges, screw bosses, flatness, visible edges, and cosmetic surfaces controlled per drawing.
Finition de surface
Anodized color controlled against approved sample coupons, agreed lighting condition, and cosmetic acceptance notes.
Max manufacturing risk
Anodizing shade can shift with alloy batch, surface preparation, part geometry, rack position, and sealing process.
DFM before / after
Before: color target was described only as a visual preference. After: approved sample coupons, lighting condition, facultatif colorimeter reading, and Delta E acceptance criteria were agreed before production.
Inspection method
Dimensional checks plus visual color review; facultatif colorimeter / Delta E readings can be documented when defined during RFQ.
Shipping documents
Packing photos, commercial invoice, packing list, and agreed inspection / finish notes included when scoped.
Lead time / result
Acheteur approval was tied to sample coupon and cosmetic review, not an unsupported universal color-match percentage.
Customer authorization
Representative case shared with customer-sensitive details removed; public photo use is limited to approved imagery.
Evidence basis
Based on anonymized RFQ notes, finish sample review, inspection planning, and packing handoff records. Last reviewed: 2026-07-01.
Devis boundary: This case does not imply default CMM, FAI, certification, regulatory approval, or production readiness. Inspection method, shipping documents, customer authorization, and documentation package must be agreed during RFQ.

Comment préparer un RFQ exploitable

Color anodized CNC case evidence

Color anodizing cases should prove both machining quality and finish handling. The buyer needs to see finish comparison, surface protection, inspection notes, and packing before shipment.

Finish decision

Compare raw machining, natural anodizing, black anodizing, and cosmetic surface requirements before approving batch production.

Donnees pour devis

Send aluminum grade, target color, gloss expectation, masked areas, threaded features, cosmetic faces, quantity, and tolerance notes.

Inspection focus

Check coating consistency, scratch risk, edge protection, critical dimensions after finishing, and packaging method before shipment.

Acheteur risk

Anodizing color can vary by alloy, surface prep, geometry, and batch, so reference samples and acceptance standards should be agreed early.

Comment préparer un RFQ exploitable

Before quoting, send the part purpose, CAD revision, material target, finish, tolerance-critical features, inspection expectations, packaging needs, and destination so engineering can price the correct route.

Ce dont les ingénieurs ont besoin pour examiner précisément

Une RFQ plus solide précise l’objectif fonctionnel, les cotes critiques, les exigences d’aspect, la quantité, les contraintes flexibles et les preuves d’inspection attendues avant expédition.
