With the advancement of society and technology, automated machinery and various equipment are gradually becoming key factors in the optimization process of various industries, such as automobiles, electronic products, robots, etc. Usually, the appearance of these automated machinery and equipment is often uniquely designed, with various curves, surfaces, and irregular structures. They have their own characteristics in function, size, and appearance, and require personalized shell design. The shape needs to be specially designed according to the internal components and layout and usage scenarios. Vacuum forming technology can well adapt to the manufacturing requirements of these complex shapes. The vacuum-formed shell can also be more easily processed with a variety of surface effects. It can bring more beautiful surface effects such as various colors and patterns through painting, silk screen printing, lamination, etc., and different textures can be made directly on the board. At the same time, compared with some other manufacturing processes, such as injection molding, the mold manufacturing cost of vacuum forming is much lower. For the shells of robots and equipment that are updated and iterated quickly, the short production cycle is also convenient for changing the mold design, which can also bring good economic benefits. In addition, the plastic materials used in vacuum forming, such as ABS, ASA, PS, PP, PC, and other materials, all have a certain degree of strength and toughness, can withstand certain external impacts and wear, and protect internal parts; plastics also have good insulation properties, which can improve the reliability and safety of the equipment. Some service robots need to have flexible movement functions. Compared with other materials, plastics also have the advantage of being lightweight. The shell made by vacuum forming can also make the robot run faster and more efficiently. In addition to insulation, materials with UV resistance, anti-slip, anti-corrosion, and other properties can be made to increase the service life of the shell.
