Abstract: Based on the design of the core modules such as apparatus main body, field control system, high-performance digital combination valve, control software and so on, we develop a multi-function anti-gravity casting system which integrates low-pressure casting, counter-pressure casting and adjustable-pressure casting. The fuzzy self-tuning PID method is used to control the production process in the apparatus operation process. It is convenient to realize the automation control of the integrated pressure casting system by the PC software, and the system has the characteristics of real-time parameter display and graphical display in casting process. The experiments show that the system is of multiple functions, strong practical applicability, can improve the automation degree and the control accuracy, and realizes the process automation of casting system.

Key words: anti-gravity, automation, integrated pressure casting
