Generally, the three most important steps in a sheet metal factory are cutting, stamping/cutting and folding.
Sheet metal processing is called sheet metal processing. Specifically, such as making chimneys, iron drums, oil tanks, oil pots, ventilation pipes, elbows, round places, funnels, etc. Through the use of plates, the main processes are cutting, bending, forming, welding, riveting and so on. This requires a certain knowledge of geometry.
Modern sheet metal processes include filament winding, laser cutting, rework, metal bonding, metal stretching, plasma cutting, precision welding, roll forming, sheet metal bending forming, die forging, water jet cutting and so on.
