Source:本站Time:2024/2/14 9:15:49

Automotive mold machine is a device used for manufacturing automotive parts, which usually consists of the following parts: mold, press machine, mold support system, cooling system, and control system. Firstly, manufacture molds based on the design drawings of automotive components. The mold is made of high-precision metal materials and has a shape identical to that of automotive components. Then, install the mold on the press machine and apply pressure to the mold through the press machine, causing the metal material in the mold to melt at high temperatures and form the shape of the automotive parts. In the manufacturing process, it is necessary to ensure the stability of the mold and the quality of the components through the mold support system and cooling system. Finally, the operation of the press is controlled by the control system to ensure the manufacturing accuracy and efficiency of automotive components.
