The form of expression of letter box craftsmanship

In fact, there are many types of electroplating for letter boxes, and there are many kinds of plating methods for letter boxes. Electrophoresis also has types of electrophoretic paints. Spraying also needs to consider what is sprayed, and baking paint also depends on the process and the type of paint. Therefore, the corrosion resistance and cost cannot be simply compared, and it depends on the specific industry.

Take the anti-corrosion of stainless steel letter box, it is generally phosphating as a whole, then electrophoresis, repainting, and finally glaze sealing, and for wheel electroplating, there are no less than 12 layers of coating on it, but the cost of simple galvanizing is only a few Divided, so it is impossible to directly compare, it depends on the specific application.

If the letter box is sprayed, frankly speaking, it is electrostatic spraying. Generally, it is sprayed with paint. In fact, is the paint a liquid plastic? In a wide range, it includes baking paint. It can be passivated and phosphated before. The shell of digital products has many applications.

If you have to compare personal opinions, electroplating should follow the general procedure. If there is a single type of plating, the corrosion resistance of electroplating is not as good as that of electrophoresis and plastic spraying, because electroplating is mostly just plating a layer of sacrificial metal on the metal surface, which will be corroded sooner or later. Yes, electrophoresis, plastic spraying, and baking paint add an insulating coating to the surface. How can plastic be more corrosion-resistant than metal, and the other three are not easy to compare. Under normal circumstances, the corrosion resistance is good. It should be able to meet the general requirements, and the cost is generally the other way around. Electroplating can be very cheap. The market requirements for letter boxes are constantly increasing.
