1. Cathode current density Any electroplating solution has a range of current density to obtain a good coating. Within the specified range of the process, with the increase of cathode current density, the cathode polarization also increases, and the finer the coating crystallization, especially when the cathode polarization rate is large, the effect is more obvious; However, when the cathode current density exceeds the allowable upper limit

According to the electrolytic law, only the average thickness of the whole surface of the plated part can be counted. Practice has proved that even on the plane cathode with the same cathode distance, the distribution of current density and coating is uneven. The coating thickness on the sharp corners and edges is obviously greater than the average thickness, and the thickness on the central surface of the plane cathode is significant

The production process carried out by the electroplating workshop can be divided into three links, namely, surface treatment before plating, electroplating treatment and post plating treatment. Electroplating equipment generally refers to the above production equipment that directly processes parts. The electroplating process includes base color electroplating, color barrier coating, laser pattern, secondary electroplating, color barrier coating removal and protective film spraying& nbs

The plating pen is the main tool for brush plating, which is composed of a handle and an anode. The anode is the working part of the plating pen. Graphite and platinum alloy are ideal insoluble anode materials, but graphite is the most widely used. Platinum iridium alloy is only used when the anode size is too small to use graphite. Wrap absorbent cotton sheath on graphite anode

Whether the selection of electroplating power supply is correct or not is directly related to the coating quality, bath production capacity, energy consumption and investment benefits. DC motor has been basically eliminated due to its high energy consumption and low efficiency; The price of silicon rectifier power supply is low, but the efficiency is not ideal. In order to further improve the efficiency of rectifier equipment, reduce the overall volume and weight

1. The last method of brush plating is called "brush plating": it is an electrodeposition technology, and not all parts are immersed in the electrolyte during the electroplating process. In this electroplating technology, only a limited area is electroplated, and there is no impact on the rest.. 2. Fingering

Electroplating equipment Electroplating technology, also known as electrodeposition, is one of the main methods to obtain metal coating on the surface of materials. It is the process of making the metal ions in the solution deposit on the surface of the cathode plated parts under the action of the DC electric field and forming a circuit by the anode and cathode in the electrolyte solution (plating solution); Current efficiency: for

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
