Choosing a Surface Finish for a Machined Part

What this page covers

• Anodizing, mainly for aluminium, for a hard, coloured, corrosion-resistant surface
• Electroplating, including chrome and nickel, for bright, hard or protective metal surfaces
• Powder coating and painting for colour and protection on metal parts
• Polishing, brushing and sandblasting for mechanical finishes, and PVD and DLC for hard, thin metal treatments

What to confirm before ordering

Each treatment is a line item in the finishing list, not a separate service page. The right finish depends on the base material, the environment and the appearance required — state all three when you send the drawing. Before ordering, confirm minimum order quantity and lead time for your drawings.

Drawing checklist

Send the drawing with units and scale stated, the material and grade, the critical dimensions and tolerances marked, and the finish required. State the quantity you need checked and the question the part must answer: fit, function or appearance. Uploaded files are used only for the quotation, and non-disclosure agreements are supported.

Quality checks

Parts are inspected with a coordinate measuring machine, a projector and height gauges, with quality control at each production stage, and a dimension report can be provided for a project on request.
