A buyer-focused guide to anodizing, passivation, polishing and finish callouts for precision-machined components.
Anodizing can improve corrosion resistance, wear performance and appearance, but coating thickness and masking requirements must be considered at tight interfaces. Define cosmetic zones separately from functional surfaces.
State finish type, color range, thickness, protected threads, contact points and acceptable appearance standards. Approved samples are especially useful for repeat cosmetic requirements.

CNC machining may have no technical MOQ, but every order carries fixed engineering, programming, tooling, setup, inspection and administrative cost. For one to five parts, unit price is dominated by t
First protect production: identify the affected drawing revision and lot, stop use, segregate stock and define a verified sort. Then establish measurement agreement, disposition authority, root cause,
Select a finish from function first: substrate, corrosion exposure, wear, electrical contact, appearance, dimensional allowance and compliance. Then define color/texture samples, masking, rack marks,
