When did the electroplated nameplate quietly become popular?

Electroplating signs used to be called electroformed signs, but now more and more people call them electroplating signs, because the layer of metal outside the signs is plated, but no one will say it was cast. Why do people not use pure metal to make signs, but to be coated with a layer of this metal? In fact, the reason is very simple, because some metals themselves are more expensive, if the whole brand is made of this metal, the price will be very, very high and unacceptable. Therefore, people use the inner layer as a low-priced metal and the outer layer as a coated metal. It is slightly similar to the silk screen label. Then Cangnan Dake brand factory will introduce some principles of electroplating signs. Electroplating is actually a chemical reaction, also known as electrolysis. Two metals pass electrolysis in the electrolyte, and another metal ion will be adsorbed to the surface of another metal, therefore, the coated label is also formed, because current is needed in the process, so it is called electroplated label. In the first stage, more and more electroplating brands are favored, because it is light, cheap and can meet the needs of customers, so corrosion signs are continuously developing.
