The materials commonly used in sheet metal processing include cold-rolled plates, galvanized plates, copper plates, aluminum plates, stainless steel plates, aluminum materials, etc. Their functions are different. As for how to choose, it is generally necessary to consider its purpose and cost. Sheet metal parts are thin metal parts that can be processed through stamping, bending, stretching, and other methods. A general definition is parts with constant thickness during the processing. Correspondingly, there are castings, forged parts, machined parts, etc. For example, the outer iron shell of a car is a sheet metal part, and some cabinets made of stainless steel are also sheet metal parts. Usually, the three most important steps in sheet metal processing plants are cutting, punching/cutting, and folding.
Sheet metal, also known as plate metal, comes from the English word "platemetal". It is usually made by manually or by stamping some metal sheets with molds to produce plastic deformation, forming the desired shape and size. It can be further welded or processed with a small amount of machinery to form more complex parts, such as chimneys, iron furnaces, and car shells commonly used in households. Sheet metal processing is called sheet metal processing. For example, using sheet metal to make chimneys, iron drums, oil tanks and pots, ventilation ducts, elbow heads, sky gardens, funnel-shaped structures, etc., the main processes are cutting, bending edges, bending forming, welding, riveting, etc., which require a certain amount of geometric knowledge.
