I advise you not to do this kind of business, it has no future at all. There are too many people in this industry and the wages are pitifully low. Change careers early. I also graduated from junior college, and I still have nothing after three years of graduation. The current salary of this industry is as follows: model repairman: 770-900, requiring more than two years of work experience. Mold technician: 900- 1200 is low, requiring more than five years of independent mold opening experience; Draughtsman: The monthly salary is about 1200- 1500 for overtime. Requirements: more than one year experience in mold drawing, assistant engineer of mold design: monthly salary 1700 or so overtime. Require more than two years experience in mold design, be able to separate and sort independently, and design simple molds.
