In order to meet the needs of small batch production of initiating explosive device, a control system was designed, which can automatically identify and continuously carry out pressing and demoulding. Through the analysis of the pressure characteristic curve in the process of pressing and stripping, the control model of the system is established. The actual test results show that the control system runs stably, can accurately identify the pressing and stripping process and switch the corresponding control program, and can meet the design accuracy requirements in the pressing mode.
