Why you may choose plating as the precision machining

DALIAN, China - May 5, 2024 - PRLog -- What Is Plating?

Plating is a common finish used for CNC machined components, a surface covering process where a thin layer of metal is added after machining.

While much plating is done for decorative purposes, still more is done to increase the durability and corrosion-resistance of softer materials. Most automotive parts, appliances, housewares and flatware, hardware, plumbing and electronic equipment, wire goods, aircraft and aerospace products, and machine tools are plated for durability.

Types of Plating

Electroplating:

Involves immersing the part in an electrolyte solution containing metal ions, such as nickel, chrome, zinc, or gold. An electrical current is passed through the solution, causing the metal ions to deposit onto the part's surface.

Electroless Plating:

Unlike electroplating, electroless plating does not require an external electrical current. Instead, it relies on chemical reactions to deposit metal coatings onto the part's surface. Common metals used in electroless plating include nickel, copper, and gold.

Benefits Of Plating In CNC Machining

Enhanced Appearance:

Plating can improve the aesthetics of machined parts by providing a smooth, uniform, and lustrous surface finish.

Corrosion Resistance:

Plating with corrosion-resistant metals like nickel or chromium can protect parts from rust and corrosion, extending their lifespan in harsh environments.

Wear Resistance:

Certain plated coatings, such as hard chrome or electroless nickel, can increase the part's resistance to wear and abrasion,protecting components from environmental factors and extending their lifespan.

Electrical Conductivity:

Plating with metals like gold or silver can enhance the part's electrical conductivity, making it suitable for electronic applications.

Solderability:

Plating with metals like tin or lead can improve solderability, making it easier to solder electronic components onto the part's surface.
