Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the product to obtain a bright and smooth surface. It is the modification of the surface of the product with polishing tools and abrasive particles or other polishing media.

Anodizing refers to the electrochemical anodizing of metals or alloys. Under the corresponding electrolyte and specific process conditions, aluminum and its alloys form an oxide film on the aluminum product (anode) due to the action of the applied current.

Sandblasting is the process of cleaning and roughening the surface of the substrate by the impact of high-speed sand flow. Due to the impact and cutting effect of abrasives on the surface of the product, the surface of the product can obtain a certain degree of cleanliness and different roughness.

Painting refers to the surface coating processing of industrial products. Spray the specified color according to the customer's ments.

This is a coating process that uses corona discharge to make powder coatings adhere to the product. A wide variety of colors are available to create the desired aesthetic.

It refers to the treatment method of chemically reacting metal with chromate to form a stable chromate film on its surface.

Passivation refers to the process in which the metal is oxidized by a strong oxidant or electrochemical method to make the surface into an inactive state.

This process is done by coating the part in a flux and dipping the part into molten zinc. The molten zinc forms a bond with the steel, creating a protective layer on the surface of the part.

Nickel plating is a process used to electroplate a thin layer of nickel onto a metal part.

Electropolishing is an electrochemical process used to clean metallic surfaces and reduce micro-roughness of stainless steel parts. Useful to remove a thin (up to 10μm) layer of material.
