Electroplating
Electroplating is an electrochemical finishing process that deposits a controlled metallic coating onto a conductive substrate. It is used to improve corrosion resistance, wear performance, electrical contact properties, solderability, and appearance across a wide range of precision industrial components.

Manufacturing overview
Electroplating uses electrical current to deposit metal ions from an electrolyte onto a prepared component surface.
Common coating metals include zinc, nickel, copper, tin, silver, and chromium.
Typical applications include fasteners, electrical contacts, connectors, precision hardware, automotive components, and industrial fittings.
Coating selection depends on the intended functional requirements.
Zinc plating is frequently used for corrosion protection, while tin and silver coatings may be selected for electrical applications.
Nickel coatings can provide decorative appearance, corrosion protection, and selected wear-related properties.
Design considerations include coating thickness distribution, recesses, internal features, surface preparation, and dimensional effects.
Buyers should specify substrate material, plating metal, coating thickness, applicable standard, appearance requirements, and post-treatment.
High-strength steel components may require additional controls to manage hydrogen embrittlement risks.
Inspection may include coating thickness measurement, adhesion testing, corrosion testing, and visual verification.
