The environment of mold workshop is very poor, and the noise is greasy and iron filings.
It's promising, but it takes time. Because the knowledge of mold design is very extensive: machinery, geometry, plastic engineering, heat and mechanics and so on. In other words, in-depth study has a future. Most people give up halfway, and only those who stick to the end are the gold after the big waves.
Mould is the mother of industry. As long as there is demand for mass production, it is inseparable from mould. Especially suitable for comrades who study science or are interested in mathematics and physics.
It is not easy for liberal arts students to learn the engineering knowledge of molds well. Even if you work hard, unless you know the technology and have the management ability, it is difficult to gain much.
