What is sheet metal processing
Sheet metal parts are sheet metal hardware, that is, parts that can be processed by the wrist by stamping, bending, stretching, etc. A rough definition is: parts with constant thickness during processing. Corresponding to castings, forging , Machining parts, for example, the iron shell on the outside of the car is sheet metal, and some cabinets made of stainless steel are also sheet metal.
The materials commonly used in sheet metal processing include cold-rolled plates (SPCC), galvanized plates (SECC), copper plates, aluminum plates, stainless steel plates, aluminum materials, etc. The functions are different. As for how to choose, generally need to use its use and The capital came up to think. This is mainly due to the following reasons. Consumption can only make progress. China is becoming an international processing and manufacturing center, and foreign investment is increasing from time to time.
The punching accuracy of sheet metal processing is usually about ± 0.1mm, and the bending accuracy can generally reach ± 0.5mm. Therefore, for sheet metal processing, the accuracy is much lower; the profit is high, such as stamping can generally reach about 30%, Laser cutting can reach 50% or more.
The demand for metal processing talents increases from time to time, and the electrical control boxes and machine housings in the metal processing industry are generally sheet metal parts. Therefore, the demand for sheet metal processing capabilities is constantly improving, the processing accuracy is low, and it is easy to get started.
As far as sheet metal processing is concerned, precision is very common in a few wires, and the complexity of the process is higher than that of some parts. Therefore, sheet metal processing enterprises usually require a variety of machinery and equipment to meet different process requirements.
