Different plating finishes can be executed based on the use of the product.
Choosing the right electroplating method is
important for achieving optimal results and minimizing the risk of damage to
the final product.
Decorative chrome plating creates a shiny, bluish tint, mirror-like finish. The chromium layer protects the nickel from oxidation and
tarnish, as well as rust and wear when products get exposed to corrosive conditions. Chrome plating
serves an essential role in many industries. Although it does not offer the
same strength and durability as hard chrome, decorative chrome finishes provides
a thin protective coating when applied to materials such as automobile parts, tools, musical instrument hardware and utensils.
This plating is used to create the
ultimate wear and corrosion resistant coating as a barrier coating under hard chrome.
The application of bright nickel rely on the nickel for a decorative appearance with corrosion protection and wear resistance.
Many items around the house, including hand tools, are
plated in bright nickel to improve their appearance, wear and corrosion
protection. Such items may include plumbing supplies, light fixtures, wire racks, components on furniture, walkers and/or wheel chairs.
This finish is primarily used as an undercoat rather than a cosmetic finish as it covers minor imperfections in the base metal. It is easy to buff or polish copper, giving it a high gloss. As a highly conductive material, it is prone to be an excellent coating for printing on circuit boards or as a coating on steel wire used to conduct electricity. Copper is among the least expensive metals and is in relatively stable supply. More leveling can be obtained for the cost of the metal electroplated than for any other metal.
This is one of the more
versatile finishes due to its excellent corrosion protection properties
and the fact that it is relatively inexpensive.
Zinc plated parts can be chromated with different colors after plating
to achieve different results for a product. The colours include black, clear, olive, yellow and blue.
Mechanical polishing is a highly specialized process and involves the utilization of processes such as grinding and buffing in order to remove scratches, gouges, and other damage appearing on the surface of a material.
The polishing process includes grinding,
polishing, and buffing, done in that order. During mechanical polishing,
defects that
may affect a part’s appearance, as well as its functionality — are eliminated.
Choosing the right electroplating method is important for achieving optimal results and minimizing the risk of damage to the final product. The 2 applied processes for plating multiple workpieces are barrel and rack plating. They both have different advantages, as well as points the plater and customer must consider when determining the most appropriate method for their project.
Barrel and rack plating are the two most applied plating techniques to work pieces.
Rack plating is different to barrel plating because parts are attached to metal racks/jigs with screws, wires or spring fingers. The parts remain stationary upon immersion of the jig into the plating solution. Rack plating is best for delicate parts that might not be able to withstand the tumbling or cascading action produced by barrel plating and also works well for large or complex components.
In addition to affording increased protection against damage to parts, the rack process can plate contours and intricate shapes more efficiently.
Disadvantages of rack plating include higher cost and increased labor requirements. In many cases, it may be necessary to design and manufacture a customized rack for specialized applications which also increases the cost.
Barrel plating entails placing the parts inside a barrel constructed of polypropylene. The barrel contains danglers with a conductive tip that conduct the electrical current. The barrel rotates slowly while immersed in the electrolytic plating solution. This causes the parts to tumble and make contact with the conducting tips and each other which provides an even, uniform coating.
Typical barrel plating applications include enhancing corrosion protection, increasing aesthetic appeal and producing an engineering finish that protects the parts against wear and tear.
Barrel plating is a cost-effective way of plating high volumes of a wide range of small parts. On the downside, most barrel plating techniques require a low electrical current, which increases the time that the parts are exposed to the plating solution.
