Metal Stamping Parts (XINGHUI) is the act of forming, trimming, embossing, flanging, piercing, or restriking a metal blank (usually steel sheet metal). It's strongly associated with the automobile industry, simply because each car has many parts that can be made from steel. Outer car panels, like hoods and fenders, are common examples of parts made using metal stamping processes.

Sheet metal is used to make many different parts, not just those associated with automobiles, of course. But, since most people have seen a car and have a basic understanding of its outer sheet metal parts, most of the references used in this article will refer to stamped metal car panels. Plastic has been substituted for sheet metal in many industries, wherever it's reasonable to do so. Plastic molding is less costly than metal forming, but many automakers will still use steel for parts that simply look better when stamped as metal, or for other concerns such as passenger safety.

This was done with a machine that presses, or forms, the metal by applying pressure to it (metals used to make coins are obviously softer than steel, and therefore more ably pressed into shape). This pressure forming is a big part of what metal stamping is. Machines are built to repetitively stamp metals, like coins, in a process known as mass production. The same concept is applied when stamping car parts from sheet metal. There are still machines all over the world, running twenty-four hours a day, that travel up and down as they stamp sheet metal. Such machines are called presses.
