An automotive mold machine is a device used for manufacturing automotive components, typically consisting of a large metal frame and a set of movable molds. The working principle of a mold machine is to heat and cool the metal, causing it to deform and form the desired shape. Mold machines can be used to manufacture various automotive parts, including body parts, engine components, wheels, and interiors. The manufacturing process of mold machines usually requires multiple steps such as design, manufacturing, testing, and debugging to ensure that they can accurately produce the required components.
