Electroplating process, give new life to metal! AFI Industries' plating services give your products a bright coat that enhances durability and beauty.
Electroplating Process
Electroplating is an electrochemical process used to coat a metal film on a metal or non-metal surface. This process involves using the part to be plated (usually metal) as the cathode and the metal to be plated as the anode, both of which are immersed in a plating solution containing the same metal ions. By applying direct current, the metal on the anode will dissolve into ions into the plating solution, while the metal ions on the cathode will be reduced into metal atoms and deposited on the surface of the plated part to form a uniform, dense metal film. The following are the basic steps of the electroplating process:
Pretreatment
The pretreatment stage of electroplating process is the key step to ensure the quality of the final coating. The purpose of pretreatment is to remove various pollutants on the surface of the substrate through a series of physical and chemical treatment means, so that it can achieve a good activation state, laying the foundation for the smooth progress of the plating process, including cleaning and degreasing, alkaline cleaning, pickling and passivation.

About Electroplating
Before electroplating, the metal surface may appear dull, vulnerable to corrosion and wear, and after electroplating, the metal surface is not only bright and smooth, but also has enhanced corrosion resistance and wear resistance, while the plating layer can provide additional protection, extend the service life of the metal, making the product appearance and performance have been significantly improved.

Electroplating Material
Electroplating can be applied to a variety of materials, mainly including the following categories:
Metal plating materials:
Steel electroplating materials: such as zinc plating, chromium plating, etc., are favored for their excellent mechanical properties and wide range of uses.
Copper and copper alloy plating materials: Copper and its alloys have good electrical and thermal conductivity, often used in electronics, construction and other fields, such as copper plating, gold plating and so on.
Nickel and nickel alloy electroplating materials: Nickel and its alloys have excellent wear resistance and corrosion resistance, and are widely used in aviation, automotive, electronics and other industrial fields.
Precious metal plating materials: such as gold, silver, etc., because of its excellent electrical conductivity, gloss and chemical stability, often used for surface decoration and functional coating.
Non-metallic electroplating materials:
Plastic electroplating material: plastic has good processing performance and light characteristics, through electroplating can form a metal coating on its surface, improve its electrical conductivity, wear resistance and other properties.
Glass and ceramic electroplating materials: Glass and ceramics are specially treated and can be electroplated to form a uniform metal coating that enhances their aesthetics and functionality.
Composite electroplating materials:

Frequent Asked Questions
It is a heat treatment process that heats and then rapidly cools a metal to increase its hardness and strength.
Because it can greatly affect the final properties of a metal by changing its molecular structure.
Quenching is commonly used for iron, steel, aluminum, and some alloys, but can also be used for non-metallic materials such as glass and polymers.
The process of heating a metal at a high temperature and rapidly cooling it causes a rapid change in the internal structure of the material, resulting in smaller, more uniform grains, which can increase the hardness and wear resistance of the metal.
Depending on the material and the desired properties of the product, the quenching methods that can be selected include air、oil、water, and salt quenching.
Metals can warp or crack during rapid cooling, as well as develop internal stresses that can affect the final shape and strength of the metal. It is important to carefully control and monitor the quenching process to avoid these problems.
