Mainly include the following types:
1. Electroless plating (autocatalytic plating) autocalytic plating
On the surface of the activated substrate, in the plating solution The process in which metal ions are catalytically reduced to form a metal coating. This is a process project that is mostly involved in our process. Through this process, we can carry out post-processing such as electroplating, and it is mostly used as a pre-processing process for plastic parts.
2. Electroplating
The process of using electrolysis to form a uniform, dense, and well-bonded metal or alloy deposition layer on the surface of a workpiece. This process is relatively complicated, but it has There are many advantages, such as the variety of metal types that can be deposited, the variety of colors that can be obtained, and the lower price compared to similar processes.
3. Electroforming
The process of manufacturing or replicating metal products by depositing metal on the mold through electrolysis (which can separate the mold from the metal deposit). This processing method is used when we require the final product to have special surface effects, such as clear and obvious polishing and etching dividing lines or special acute angles. Generally, copper material is used to make the shape of a component, and then through the electroplating process The method is to deposit the alloy on its surface, usually with a thickness of several tens of millimeters, and then cut the cavity and insert them into the cavity of the mold respectively to inject the plastic parts. The parts processed in this way have edges and corners and several faces There will be special effects on the boundaries to meet the design needs. Usually we see a lot of plastic parts with clear boundaries between high-gloss and etched plating effects after electroplating. Those with higher quality requirements usually use this method for design. If the angular key board is manufactured using electroforming technology, it will achieve a good appearance.
4. Vacuum plating
Vacuum plating mainly includes vacuum evaporation, sputtering and ion plating. They are all used under vacuum conditions, through distillation or Sputtering and other methods are used to deposit various metal and non-metallic films on the surface of plastic parts. In this way, a very thin surface coating can be obtained. It also has the outstanding advantage of fast speed and good adhesion, but the price is also high and can be operated. There are fewer types of metals, and they are generally used for functional coatings on higher-end products, such as internal shielding layers.
