Of course. 1. You can declare the title of assistant engineer in the local personnel bureau. There is no such thing as casting assistant engineer. (It can be declared by the company, and the cost is very low)

2. You can attend the training course jointly sponsored by China Foundry Association and Tsinghua University, and the certificate of foundry assistant engineer will be issued by China Foundry Association after graduation. (You can go to the website of China Foundry Association to check whether it has been opened this year, and the cost is a bit high. )
