Sheet metal processing is called sheet metal processing. Specifically, for example, the use of plates to make chimneys, iron barrels, oil tanks, ventilation pipes, elbow sizes, round places, funnel shapes, etc., the main processes are cutting, bending, bending, welding, riveting, etc., which requires certain geometric knowledge. Sheet metal is sheet metal hardware, that is, parts that can be processed by stamping, bending, stretching and other means, and a general definition is the parts that do not change in thickness during processing. The corresponding parts are cast parts, forging parts, machined parts and so on.

Sheet metal process in general, the basic equipment includes Shear Machine (Shear Machine), CNC Punching Machine/laser, plasma, water jet Cutting machine (Cutting Machine), Bending machine (Bending machine) Machine), drilling machine and various auxiliary equipment such as: uncoiling machine, leveling machine, deburring machine, spot welding machine, etc.

In general, the four most important steps of sheet metal process are cutting, punching/cutting/folding/rolling, welding, surface treatment, etc.

Sheet metal working

Sheet metal is sometimes also known as metal plate, the word comes from the English platemetal, is generally some metal sheet through manual or mold stamping to produce plastic deformation, form the desired shape and size, and can be further through welding or a small amount of mechanical processing to form more complex parts, such as the chimney, iron furnace commonly used in the family. And the shell of the car is all sheet metal.

Sheet metal is sheet metal hardware, that is, parts that can be processed by stamping, bending, stretching and other means, and a general definition is the parts that do not change in thickness during processing. Corresponding to casting parts, forging parts, machining parts, etc., such as the iron shell outside the car is sheet metal parts, and some cabinets made of stainless steel are sheet metal parts.

Modern sheet metal processes include: filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending, die forging, water jet cutting, precision welding, etc.

The surface treatment of sheet metal parts is also a very important part of the sheet metal processing process, because it prevents parts from rusting and beautifies the appearance of products. The role of surface pretreatment of sheet metal parts is mainly to remove oil, oxidation, rust, etc., which is to prepare for surface post-treatment, and then the main treatment is to spray (bake) paint, spray plastic and plating anti-rust layer.
