The main body of the Three Stations Fully Automatic Plastic Pvc Fruit Box Vacuum Forming Machine: Fruit Box Vacuum Forming Machine is formed by splicing and welding steel structure profiles such as square pass and channel steel, which is used for assembling heating, mold table forming, mold table punching, and auxiliary devices. The overall steel structure frame is guided by the, and all the parts involved are fully in line with: high-quality selection of materials, blank production methods, machining, heat treatment, parts assembly, machine operation, machine maintenance, and other technological foundations, To ensure that the movable device that transmits and transforms motion and force has sufficient strength and rigidity. All metal surfaces are treated with anti-rust and the bottom layer is sprayed with anti-rust paint; common parts and standard parts are used in the structure, which is convenient for later maintenance and replacement of all parts.
