How do you keep anodize or finish color consistent across batches for Smart Home actuator shaft & ge
Why color drifts
For Smart Home actuator shaft & gear with a visible finish, batch-to-batch color shift comes from alloy lot, bath chemistry and current density. LusterControl controls it with in-house anodize/electropolish, batch-locked process parameters and a color check against an approved master — so your quiet runout & cosmetic finish concern stays contained.
What to agree
- A signed color master (Pantone or sample).
- One alloy lot per production run where possible.
- A color-check record in the lot traceability file.
Spare-part reproducibility and rework assurance.
