Electroplating technology, as a very important modern processing technology, has not only been a means of metal surface protection and decoration processing, but also the advantages of giving metal and non-metal other functions.
According to incomplete statistics, there are more than 60 kinds of industrial electroplating available at present, among which there are more than 20 kinds of single metal plating, which almost contains all the common metals or rare metals. There are more than 40 kinds of plating, but there are more than 240 kinds of alloy under study. Then according to the actual production situation, different plating treatment methods have been developed.
The following describes several common electroplating processing methods:
Electroplating is the process of electroplating a thin layer of other metals or alloys on a metal surface using the principle of electrolysis. It is the process of using electrolysis to attach metal film on the surface of metal or other material components to play the role of protection, decoration, and even special functions.
Electroplating can be divided into suspension plating, rolling plating, continuous plating and plating and other methods, mainly involving the size and batch of electroplated materials.
1) Suspension plating refers to the workpiece is installed on the hanger clamp, suitable for large parts, each batch of products can be plated less, plating thickness of more than 10m process, car bumper, bicycle steering wheel, electroplating line can be divided into manual line, automatic line.
2) Continuous electroplating, simply put, is an object along the flow of continuous electroplating, across the different plating tank to complete the plating process, suitable for mass production of wire and strip.
3) Electroplating is a method of selective electroplating by moving the electric end or brush connected with the positive end and able to supply the electrolyte required for electroplating on the product as the negative end. It is suitable for local electroplating or repair.
4) Roller plating is usually suitable for small parts, roller plating is strictly called roller plating, is a certain number of small parts into the special roller, in the rolling state of indirect electricity, so as to accumulate a variety of metal and alloy plating on the surface of the parts, surface protection decoration and various functions for the purpose of plating processing, according to the use of different rollers, The common drum electroplating methods in electroplating production can be divided into horizontal drum electroplating, tilted drum electroplating and vibrating drum electroplating.
At present, the diversification of electroplating processing methods, choosing the correct electroplating processing methods, is conducive to the plating factory standard, scientific and orderly production, as the traditional metal surface treatment technology, electroplating processing needs to be more careful in production, with the development of science and technology, electroplating technology has been gradually replaced by environmental protection innovative alloy catalytic solution, in the actual production, Electroplating technology has seriously hindered the growth of enterprises. The alloy catalytic solution in the field of metal surface treatment has improved the production defects of electroplating technology.
