Prototype processing is a method of quickly manufacturing product prototypes. The main purpose is to quickly verify the correctness of product design, test product performance and other related factors, so as to guide process adjustment and design optimization before mass production. Hand plate processing is usually processed by CNC processing equipment, which can be precisely processed according to CAD design drawings. Common prototype processing materials include ABS, PC, PP, PVC, PMMA and other engineering plastics and aluminum alloy and other metal materials. Prototype processing can produce fine and accurate product prototypes, which can visually display the designer’s ideas, and facilitate the testing and verification of product performance and structure.
