After the product is put on the market, it is called nameplate, which is fixed on the product and provides users with information such as manufacturer's trademark identification, brand differentiation, product parameters and so on. Nameplate, also known as nameplate, is mainly used to record some technical data and rated working conditions of the manufacturer, so as to use it correctly without damaging the equipment.

Generally speaking, there is no patent number on the nameplate, but if the manufacturer needs special customization, it can also specify the printing patent number.
