Plating is a process where a conductive surface is covered with a thin layer of metal. It is commonly used to prevent corrosion, increase durability, alter surface friction, and improve appearance.

Black oxide is a low-cost finishing method for adding corrosion resistance, reducing reflection, and enhancing the appearance of parts. As a final step, an after-finish of oil, wax, or lacquer is applied for added corrosion resistance.

Polishing is one finishing loose abrasive process, used to generate surfaces with very high tolerances in geometry, surface integrity, and roughness characteristics, either through physical rubbing of the part or by chemical interference.

Powder coating forms a durable, wear resistant and corrosion resistant layer on the surface of parts. Powder coating can be used to apply colors to parts and is compatible with any metal.

Painting is commonly specified by engineers to enhance a part’s appearance and corrosion resistance. In addition, painting can have a protective effect on parts. For example, surface painting is an effective method to protect metal from oxidation and corrosion.

Surface grinding is a process that creates a precise, smooth flat-surface by moving a workpiece back and forth under an abrasive grinding wheel. They are commonly used when making machine tools, reference surfaces, jig plates, and optical platforms.

Laser marking is a low-cost method of adding text, logos, and graphics to parts. Similar to engraving, but using a CO2 or fiber laser.
