In the process of mechanical processing and production in Dalian, the process of changing the shape, size, position, and properties of the production object to make it a finished or semi-finished product is called a process. It is a major part of the production process. The manufacturing process can be divided into casting, forging, stamping, welding, mechanical processing, assembly and other processes. The mechanical manufacturing process generally refers to the sum of the mechanical processing process of parts and the assembly process of machines.
