Electroplating is to deposite a metal on a conductive surface of CNC machining workpiece. Some of benefits for plating include: increased resistance to corrosion, improved hardness, superior strength, resistance to wear, improved IR reflectivity improved ductility, improved solderability, improved paint adhesion, altered conductivity and for other purposes.
 
Different plating chemicals incorporated into the process deliver anything from a semi-bright and fully bright cosmetic effect, matte or satin finishes.

Anodizing is an electrochemical process that could convert the surface of aluminum alloy into a decorative, durable, corrosion-resistant, oxide layer finish. Aluminum is ideally suited to anodizing. Magnesium and titanium also can be anodized. The CNC machining parts being anodized will be featured with:

• Better anti-corrions resistance
• Decorative appearance
• Electrical insulation
• Enhanced adhesion for coating

Alodine is one of chromate conversion coating that protects aluminum and other metals from corrosion, also called chemical film or chemical conversion. 

Black oxide is an exceptionally thin process which is an iron based oxide film. It is formed by putting iron parts into a hot and strong alkaline aqueous salt solution with nitrates and other ingredients. However, it is also possible to oxidize non-ferrous metals under suitable conditions to form black oxides. It is recommended to apply an after-finish treatment for black oxided component, such like with an oil or wax to achieve excellent anti-corrosion protection.

Zinc plating is widely used for anti-rust purpose in industrial components. Zinc plating is to electrodeposit a thin layer of zinc metal onto the surface of metal object, known as a substrate. The zinc coating layer creates a physical boundary that prevents rust from reaching the underlying metal surface.

There are generally two plating methods for applying zinc coatings include the use of rack and barrel plating processes. We normally apply rack zinc plating for smaller or delicate parts which couldn't withstand rotating tumbling barrel. As for barrel zinc plating, it is much more cost effective for plating many parts at once.

Electroplating is to deposite a thin metal layer on a conductive surface of CNC machining workpiece. Some of benefits for plating include: increased resistance to corrosion, improved hardness, superior strength, resistance to wear, improved IR reflectivity improved ductility, improved solderability, improved paint adhesion, altered conductivity and for other purposes. Different plating chemicals incorporated into the process deliver anything from a semi-bright and fully bright cosmetic effect, matte or satin finishes. Generally speaking, chrome plating is much brighter than nickel plating.

Another choice of chrome plating, hard chrome is available for reducing friction, improving durability through abrasion tolerance and wear resistance in general. Hardness can be up to HRC65~69.

Electroplating is to deposite a metal on a conductive surface of CNC machining workpiece, usually on a metal one. Some of benefits for plating include: increased resistance to corrosion, improved hardness, superior strength, resistance to wear, improved IR reflectivity improved ductility, improved solderability, improved paint adhesion, altered conductivity and for other purposes.

Different plating chemicals incorporated into the process deliver anything from a semi-bright and fully bright cosmetic effect, matte or satin finishes. The main benefits for nickel plating is likely cosmetic and anti rust purpose.
