Shell making process is a key part of the precision casting process, usually we define 18 kinds of defects related to the shell, and easy to occur, shell making process is also a high incidence of occupational diseases, so making the shell is both the focus and the difficulty.

Melting process is a key link in the precision casting process, the success or failure of melting, directly determines the quality of the product, so our company in the production process, pay much attention to the control of the melting process.

Staffing: general melting process a group of four people, one for the melting master, three fork shell workers, we are in accordance with the annual production capacity of 1320T configurationEquipment.
