Nameplate is a nameplate fixed on the product to provide users with information such as manufacturer's trademark identification, brand differentiation, product parameters and so on after the product is put on the market.

The nameplate is mainly used to record some technical data and rated working conditions of the manufacturer, so as to be used correctly without damaging the equipment. Nameplates are made of metal and nonmetal. Metals include zinc alloy, copper, iron, aluminum, stainless steel, etc. Among them, aluminum is mainly used for production, because the processed nameplate is relatively high-grade and durable and does not rust. Non-metals include plastic, organic acrylic board, PVC, PC, paper and so on.

Nameplates are divided into concave-convex nameplates and plane nameplates. Ordinary concave-convex nameplate, the paint filled in the concave part is nitrocellulose paint. 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.
