Whether it is the production of structural prototypes or appearance prototypes, it is very important in the process of product production and promotion. The designed product is tested by the prototype to check whether the appearance and structure design is reasonable. It is the most intuitive way to find the problems in the early stage. It provides a visual inspection basis for the subsequent smooth mass production and avoids the risk of direct mold opening.

The early prototype model was restricted by various conditions, and most of its work was done by hand. This made the prototype model's processing period long and it was difficult to strictly meet the size requirements of the appearance and structure drawings, so its inspection appearance or structure Sexual functions are also greatly reduced.

With the advancement of science and technology, the rapid development of CAD and CAM technology provides better technical support for prototype model manufacturing. The popularization of CNC machining centers (CNC), precision engraving machines, CNC milling machines, laser forming machines and post-process production supporting equipment has made prototype production truly accurate and fast.

CNC (Numerical Control Processing)

The advantage of CNC machining is that it can accurately reflect the information and material characteristics expressed in the drawings. The surface quality is high, but the technical requirements are high. At present, the production of prototype models based on CNC technology has become an industry and the mainstream of the prototype manufacturing industry. The prototypes mentioned in the industrial design industry generally refer to prototypes made by CNC machining.

The typical processing process of the prototype model industry can be roughly divided into 9 processes, including drawing files, pre-analysis, CNC programming, CNC processing, manual correction, polishing and polishing, spraying and silk screen printing, manual assembly, quality inspection and delivery.
