Finishing and plating
Anodize, Gold Plate and Laser Mark in Sequence
Machined aluminum rarely ships bare. We run anodizing in clear, color, hardcoat and conductive types, plus electroless nickel, zinc, silver and gold plating. Gold plating on aluminum needs a proper zincate and nickel strike underneath, otherwise the deposit blisters at temperature or flakes at the edge of a thread.
Masking decisions get made at the drawing stage, not after plating. If a grounding pad or a press-fit bore must stay conductive, we call it out before the parts go to the line. Laser marking is available to a minimum character height of 1.5 mm, which is the practical floor for a readable mark on a curved surface.
