Different finishing services for lock products(Part 1)

There are many metal finishing services for lock products, including electroplating, polishing, painting, lacquering and spraying, electrophoretic coating, anodizing, and powder coating.


Different finishing services for lock products:

Different finishing services for lock, Electroplating is a process of plating a thin layer of other metals or alloys on some metal surfaces by electrolysis. It is a process of attaching a metal film to the surface of metal or other materials by electrolysis in order to prevent metal oxidation such as rust, improving wear resistance, electrical conductivity, light reflectivity, corrosion resistance, and appearance.

Electroplating includes tin plating, silver plating, gold plating, chrome plating, nickel plating, copper plating, satin finishing, barrel plating, zinc plating, etc.

Tin Plating

Tin plating is a kind of electrolytic process. The purpose of tin plating is to protect the metal surface from corrosion. Tin is often applied to the first coating of copper.

Benefit of tin plating

Tin stannate tin plating is a coating which has lower cost than the other protective coatings. Tin has good conductivity enhancement properties, which is different from silver with higher conductivity. Tin can be welded easily, so it is a coating that is necessary for later welding of  components.

Colour of tin plating

Tin plating has a “gray-white” hue and often does not have a bright nickel layer for decorative coatings because of the dull appearance of tin.

Applications of tin plating

Due to the easily welding and good electrical conductivity performance of tin, tin plating can be used for electronic components with low technology such as electronic connectors, commercial cooking equipment and welding parts

Tin can be plated on most metal substrates. However, it is often used in substrates with low value such as copper alloys or mild steel.

Design matters of tin plating

Since this is an electrolysis process, it is necessary to use a jig, rack or wire to provide current conduction. It is necessary to add gates or holes. If you plan to use this process, please consult your plating consultant before finalizing the design.
