Specify zinc plating by requirement
Zinc plating services should be quoted against a defined substrate and customer specification. Identify the material grade and required coating standard, including the stated thickness or class where applicable. Color or passivation requirements should be named explicitly rather than inferred from the term zinc plating.
Protect fits, threads and functional surfaces
Mark areas to mask, threads, mating faces and dimensions that need post-plating review. If the part has a heat-treatment or strength-related requirement, state it so the process route can be reviewed against the drawing and applicable customer requirements. Do not assume every plating sequence is interchangeable.
Plan inspection and documentation
List the measurement method, sample plan, coating records and packaging requirements. Use the current drawing revision and quantity, and identify any acceptance samples or approval steps. For performance or regulatory requirements, provide the controlling specification and required evidence.
For overall finishing scope, see CNC surface finishing services. For anodized aluminum requests, see anodizing services for machined parts.
