Custom Keychains come in a variety of shapes, including cartoon shapes, brand shapes, and simulation models. Copper, aluminum, rubber, plastic, and other materials are commonly used, and the zinc alloy surface is nickel-plated or rhodium-plated with anti-rust elements. Why should we use the electroplating process for the metal keychain if the outside will be electroplated?
The process of plating a thin layer of other metals or alloys on the surface of a metal keychain using the principle of electrolysis is known as electroplating. It is the process of attaching a layer of metal film to the surface of a metal keychain using electrolysis to prevent oxidation. (Such as rust), improve the metal keychain's wear resistance, conductivity, reflectivity, and corrosion resistance (copper sulfate, etc.), and enhance the metal keychain's beauty.

The electroplating keychain requires a low-voltage, high-current power supply to the electroplating tank, as well as an electrolytic device made up of an electroplating solution, the keychain to be plated (cathode), and the anode. The composition of the electroplating solution varies depending on the plating layer, but they all contain the main salt of the metal ion that provides the metal keychain, as well as the complexing agent, which can complex the metal ions in the main salt to form a complex and is used to stabilize the electroplated keychain solution, PH buffer, anode activator, and special additives.
The electroplating process involves reducing the metal ions in the plating solution to metal atoms via the electrode reaction under the action of an external electric field, and then depositing the metal on the cathode of the metal keychain. As a result, this is a metal electrodeposition process for metal keychains involving liquid phase mass transfer, electrochemical reaction, and electrocrystallization. When electroplating metal keychains, the quality of the anode material, electroplating solution composition, temperature, current density, power-on time, stirring intensity, precipitated impurities, power waveform, and other factors will affect the coating quality and must be controlled promptly. To begin, the electroplating solution for metal keychains contains six components: the main salt, an additional salt, a complexing agent, a buffer, an anode activator, and additives.
The electroplating solution of metal keychains, the electroplating reaction of metal keychains, the principle of electrodes and reactions, and the electrodeposition process of metal keychains are all aspects of the electroplating principle.
Metal keychain coatings are typically a single metal or alloy, such as titanium palladium, zinc, cadmium, gold or brass, bronze, and so on; some metal keychains also have a dispersion layer, such as nickel-silicon carbide, nickel-graphite fluoride, and so on; and there are metal keychain cladding layers, such as copper-nickel-chromium layer on steel, silver-indium layer on steel, and so on. Non-ferrous metals are used as the base material of electroplated metal keychains, in addition to iron-based cast iron, steel, and stainless steel.
