For the surface condition and processing requirements during electroplating, select the appropriate steps to carry out necessary trimming and processing on the surface of the parts, so that the parts have a smooth and clean surface, which is an important link to obtain high-quality coating. In the pretreatment process of plating, the main equipment used are grinding, polishing machine and brush

At present, most of the rectifier transformers are three-phase five column core energy-saving transformers, which eliminates the balance reactor than the six phase double reverse star rectifier with balance reactor. Electroplating equipment manufacturers reduce costs and improve efficiency. The maintenance of thyristor power supply is more complicated. During maintenance, the fault position shall be distinguished first, and the multimeter DC shall be used first

The automatic control of crane on electroplating production line is the key to the automatic control of electroplating production line. The electroplating production line is completed by 4 cranes according to its process requirements, and each crane runs according to its own program. This production line is composed of 32 stations, and station slots 7, 15 and 22 are used for traveling

The control of process temperature is the top priority in the electroplating process. If the temperature fluctuates greatly, it will directly affect the quality of electroplating and cause energy waste. The existing electroplating equipment has taken this into consideration when designing, and the pre heating function is set on its human-machine interface, through which the pre heating

The common power supply of electroplating equipment has the following five types: 1. DC generator DC generator belongs to the early electroplating power supply, which has the advantages of stable power supply and large overload capacity, but it has large energy consumption, low efficiency, large noise, and poor economy. Large electroplating workshops are seldom used, and only small-scale temporary production electroplating workshops are used. 2、 The rectifier is generally composed of casing, rectifier element

1. Process flow of high-speed electroplating line without isolation coating:<br>transmission steel belt on the frame clamp (manual tangent feeding, flap feeding or automatic magazine feeding) → chemical or electrochemical degreasing → hot water spray cleaning → surface deoxidation → pure water spray → surface activation → electrotinning → pure water spray coating → acid-base neutralization → hot purity
