Electroplating, as a common product process in production enterprises, is believed to be familiar to everyone. Moreover, the heavy metal electroplating wastewater that is difficult to treat after passing through the electroplating process needs to be treated. Xihai Environmental Protection is particularly skilled in electroplating wastewater treatment and recycling technology, and even meets the standards in Table 3. Now, let me briefly introduce how electroplating is classified:

Electroplating made of materials

Metal plating, plastic plating

Metal electroplating: The substrate is metal, such as iron, zinc alloy, copper alloy, etc

Plastic electroplating: The substrate is plastic, mainly ABS

The pre-treatment techniques are completely different for different substrates, but the subsequent electroplating is basically the same

Electroplating according to the process

Electroplating, vacuum electroplating;

Electroplating: The process of depositing metal or alloy on the surface of a workpiece using electrolysis to form a uniform, dense, and well bonded metal layer is called electroplating. We understand this relatively simple concept as a combination of physical and chemical changes

Vacuum electroplating: including sputtering electroplating, ion electroplating, and vacuum electroplating. This is actually a process of depositing a series of metal and non-metal films on the surface of plastic parts through distillation and sputtering under vacuum conditions. Compared to thin surface electroplating, this method has a series of advantages such as good adhesion and fast speed. However, this electroplating is also expensive and has few types of operable metals. It is generally used for functional electroplating of high-end products, such as internal shielding

Electroplating according to the electroplating layer

Aluminum plating, tin plating, nickel plating, silver plating

Classify according to electroplating materials

Electroplating according to purpose

Functional electroplating, decorative electroplating;

Functional electroplating: Utilizing other properties of electroplating to enhance product functionality. These functions include mechanical functions, chemical functions, thermal functions, magnetic and electrical functions, biological functions, etc. Mainly represented by hard chrome plating

Decorative electroplating: mainly used for exterior surfaces and accessories to achieve clean and bright white eyes
