Mold design is better, fitter and CNC belong to the mold industry, but they are mainly operators or frontline workers. From the development space, working environment and salary level, the design is not good. Generally speaking, the CNC machining center is around 2000, and the programming is better. Some work experience can reach 3000 or more, but few can reach 5000. Mainly depends on the technical level, assemblers should. Mold design, the primary mold designer is about 3,000-4,000, and the three-year work is generally about 4,000-5,000, not to mention the advanced one. 3D modeling depends on which industry it belongs to. If it is still the mold industry, small and medium-sized enterprises generally use more, with an average level of around 2000. If the technology is strong, it will be around 2500. If you want to learn, it is better to develop in design. If you choose a school, I suggest you go to Nantong Tianyi Education, where you can train mold designer professionally, and your technical reputation is still very good. If you study, you'd better not miss it. good luck ...
