How to choose the plating method

With the wave of Industry 4.0 sweeping the globe, China officially released the 10-year plan of "Made in China 2025", a new generation of information technology, high-end CNC machine tools and robots, aerospace, marine engineering equipment and high-tech vessels, advanced rail transit equipment , Energy-saving and new energy vehicles, electrical equipment, high-performance medical equipment and other areas of vigorous development, will promote the rapid development of electroplating industry.

As the most important modern processing technology, electroplating technology has long been not only the means of metal surface protection and decoration, but also the advantage of giving other functions of metal or nonmetal.

According to incomplete statistics, more than 60 kinds of industrial coatings are available now, of which over 20 are single-metal coatings, covering almost all commonly used metals or precious metals. There are more than 40 alloy coatings, but more than 240 alloys are under study. And according to the actual production situation, developed a different plating treatment.

Here are some common plating processing methods:

Plating is the use of electrolysis principle in some metal surface coated with a thin layer of other metals or alloys, is the use of electrolysis to metal or other materials attached to the surface of a layer of metal film process to play a protective, decorative and even Given the special functions and so on.

Plating is divided into hanging plating, barrel plating, continuous plating and brush plating and other ways, mainly to be plated pieces of the size and volume related.

Hanging plating, barrel plating, continuous plating and plating of the applicable object

(1) Hanging plating is a process that the workpieces are clamped on the hanger, which is suitable for large parts, each batch can be plated with a small number of products and the coating thickness is over 10μm. Such as car bumpers, bicycle handlebars and so on. Hanging plating production line can be divided into manual line, automatic line.

(2) continuous plating, in short, is an object according to the process of non-stop electroplating through different plating tank to complete the entire plating process, suitable for mass production of wire and strip.

(3) Brush plating is an electrode or brush that is connected to the anode and provides the electrolyte required for plating. It is a method of selective plating that moves on a workpiece as a cathode and is suitable for partial plating or repair.

(4) barrel plating is usually suitable for small parts. Rolled plating is strictly speaking called drum plating, he is a certain number of small parts placed in a special drum, a conductive state in the rolling state of the parts deposited on the surface of a variety of metal or alloy coating to achieve the surface protection decoration And a variety of functional purposes of a plating processing methods. According to the use of different drums, the common plating in the plating production is divided into horizontal barrel plating, barrel plating and vibration when inclined inclined barrel three categories.

The above 4 is a common plating processing methods, and with the development of technology, electroplating process showed a diversified development. Plating baths, formulations and additives, electroplating power also continue to develop.
