What do mold design apprentices usually do?

An apprentice in mold design must first be very proficient in various drawing software, including drawing. Followed by machining, accuracy and roughness, then inspection, and finally die test. Generally, apprentices go from foundation to depth step by step. The process is a bit slow and there are too many things to learn. After learning, I will slowly contact the design on the basis of the original template, and finally design independently.
