Advantages and drawbacks of electrodeposition coating technology in the actual production process

No matter metal or plastic is directly exposed to air, it will inevitably be oxidised, this is because the composition of air is very complex and impurities are many, no one can guarantee that long exposure to air can still keep the product brand new, especially some metals, such as iron, it is the most vulnerable to corrosion by oxygen and moisture in the air.

In order to overcome this phenomenon, people have invented electrophoretic coating processing, the so-called electrophoretic coating is to spray paint the surface of the product, wrapped with a layer of electrophoretic coating, effectively preventing the metal or plastic from being corroded by the air. 

So what are the advantages and drawbacks of electrophoretic coating when it comes to the specific process?

1. Generally speaking, electrophoresis processing with guaranteed quality and operating techniques can result in a high degree of transparency and lustre, making the surface of the metal very bright, which has a very good effect on the aesthetics of the product. 
2. In addition, the hardness of the electrophoretic coating is so high that some metals that may not be hard on the surface can be made very strong by the electrophoretic process. 
3. Of course, the purpose of the electrophoresis process itself is to resist corrosion and rust, which is naturally needless to say, and is quite reliable as the air and impurities are kept out and the metal itself is protected by a sealed layer of electrophoresis coating on the outer surface.

However, in the actual production process, people also find that electrophoresis processing has some drawbacks. For example, many manufacturers find that the electrophoresis processing equipment is expensive, and the maintenance and operation costs are also relatively high, and the usual management requirements have to be done very strictly, which is troublesome for people. 

And for different metals, the electrophoresis processing needs to adjust different working voltages, which means that the simultaneous electrophoresis processing operation cannot be carried out for different metals. 

The pendant of the electrophoresis processing equipment is also more difficult to clean, and belongs to the easily consumed material, so it needs constant attention, which also increases the usual workload and management volume.

In general, the development of electrophoresis processing technology still has a long way to go, we should not only appreciate the advantages of electrophoresis processing technology, but also the shortcomings of the technology in the specific production process should be improved, so as to obtain a long development in the road.
