In general, the three most important steps in sheet metal fabrication are shearing, punching/cutting, and folding. Sheet metal and plastic sometimes, this word is derived from the English sheet metal, usually to some sheet metal by manually or stamping mould make its produce plastic deformation, forming the desired shape and size, and can be further by welding or a small amount of machining to form more complex parts, such as chimney is commonly used in family, tin furnace, and motor shell are automobile sheet metal parts.
Sheet metal processing is called sheet metal processing. For example, the use of plates to make chimneys, iron barrels, oil tanks, ventilation ducts, elbow sizes, round places, funnel-shaped, etc., the main procedures are shearing, bending and buckle edge, bending forming, welding, riveting, etc., which requires certain geometric knowledge.
Auto sheet metal parts are sheet metal parts, which can be processed by means of stamping, bending, stretching, etc., a general definition is the thickness of the parts in the process of processing. Corresponding is the casting, forging, machining parts, such as the outside of the car iron shell is auto sheet metal parts, stainless steel made some cabinets are also auto sheet metal parts.
