What are the processes of sheet metal processing?
First, the metal is cut into flat plates. These metal plates are then formed into the desired shape using various methods such as stamping, bending or welding. Finally, the object is completed by adding a coating or surface treatment.
Shearing:
It is the use of a shearing machine to cut metal sheets. It is mainly used for die punching and forming preparation processing. It has low cost and precision less than 0.2mm, but it can only process non-holes and cannot cut corner strips or blocks.
Stamping:
It is the use of a punch press to punch parts on the sheet in one or more steps to form materials and parts of various shapes. Its advantages are short cost and time, high efficiency, high precision, low cost, and suitable for mass production, but molds must be designed.
CNC cutting:
CNC flame cutting and CNC plasma cutting are the two main ways to cut metal in sheet metal processing, mainly used for complex graphics processing and small batch production.
Water jet cutting:
It can cut materials into any shape. Moreover, no heat-affected zone is generated during water jet cutting, and it is mainly used to process materials that are not suitable for heat treatment.
Laser cutting:
It uses laser cutting to cut structural shapes on large plates. Like NC materials, laser programs need to be written. It can be plates of various complex shapes. The cost is high and the accuracy is 0.1mm. Sawing: It is mainly used for cutting aluminum, square tubes, drawn tubes, and round bars. It has low cost and low accuracy.
