Self-service terminal products are widely used in our daily life, such as bank self-service teller machines, self-service printing terminals, charging piles, self-service selling terminals, etc. Compared with ordinary consumer products, self-service terminal design is more complex and precise, and the requirements are higher. As far as its appearance design is concerned, it needs to do more surface treatment to achieve the desired effect of the designer.

The sheet metal process is a surface treatment process needed by the self-service terminal. It is a complex process involving many aspects, including the sheet metal construction method, the design of sheet metal punching and cutting, grooves and punching, modeling printing, molds and punching, bending, etc. Whether the sheet metal material can be scientifically and reasonably applied to the production and manufacture of products, the proficiency of sheet metal technology plays a great role. The higher the proficiency of sheet metal process, the easier it is to realize the production and manufacture of products.

Sheet metal is a commonly used material for self-service terminals. Due to its complicated process, it is difficult for self-service terminal design to realize rich surface changes in appearance. If the surface treatment is improper, the equipment will appear rough and heavy, without quality feeling, and it is difficult to meet the personalized consumption needs of users. In response to this, the professional industrial design department seeks intuitive and concise design on the appearance of self-service terminal design, and on the basis of the existing technology, it does more and more delicate process treatment on its surface, and focuses on details. Specialize, make the texture of the equipment comfortable, and give people an intuitive, concise and atmospheric beauty. The treatment of the appearance surface of the self-service terminal design can also indirectly reflect the professionalism of the designer and the industrial design company, the delicate surface process treatment, the atmospheric and beautiful shape, and the professionalism of the equipment can be highlighted.

Of course, the difficulty of surface processing is only one of the problems encountered in the design process of self-service terminals. To do a good job in the appearance design of self-help terminals, designers also need to comprehensively consider the modeling design, color expression, material selection, etc., and on the basis of realizing the structure and function of the equipment, integrate their own creative and flexible design, so that the equipment is simple and beautiful and comfortable to use.
