Nowadays, metal prototype can be made by 3D printer and cnc machining, and other processed, such as: sheet metal, welding, rapid casting, .etc. But the production cost of metal part is too much with 3D printing, and surface is rough, not easy to polish. In western country, many prototype manufacturers have 3D printing machine for printing metal part. But in China, just a few, we often make metal prototype parts by CNC machining in China. So CNC metal prototype is popular in Chinese prototype factory.
Because of lower of the labor cost in China, we have much more competitive in CNC service prototype to compare with western supplier. With more and more communication with western customers, Chinese manufacturer know how to produce the high quality prototype parts to meet customer requirements from all over world.
