Nameplate refers to the nameplate that is fixed on the product and provides users with information such as manufacturer's trademark identification, brand differentiation and product parameters. After the product is put on the market, it is also called signboard.

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. Nameplates are made of metal and nonmetal: metal includes zinc alloy, copper, iron, aluminum, stainless steel and so on. However, aluminum is mainly used in production because the processed nameplates are high-grade, durable and do not rust. Non-metals include plastic, organic acrylic board, PVC, PC, paper and so on.

For example, electrical appliances are printed on paper, and the outer packaging is engraved with a metal plate, which mainly records the name of the manufacturer and the rated technical data of the product. The characters and symbols used on Chinese nameplates shall all use the legal standards of China, and the imported products that need to be equipped with Chinese nameplates shall also be handled accordingly.

Nameplates are divided into concave-convex nameplates and plane nameplates. Ordinary concave-convex nameplate, the paint filled in the concave part is nitrocellulose paint. The painting method is to completely paint the front of the nameplate.

Then remove the pigment from the font or pattern to expose the metal characters or pattern lines. High-grade concave-convex nameplates are only painted with baking paint, or partially painted with colored paint, or painted with transparent varnish, as required. The plane nameplate is mainly made of aluminum alloy, and its surface color is not paint, but anodized color, which can be monochrome or 2-3 colors according to different process methods. The plane nameplate has high decoration and low price. There are also screen-printed nameplates, and the color used is ink.
