Adopting a computer control system, it consists of a complete set of equipment and processes such as explosive preparation, cable making, coding, plastic coating, coiling, packaging, etc. According to the different outer layers, it can be divided into cotton detonating cord and plastic detonating cord. Real time safety monitoring (temperature, wire breakage, etc.) is implemented for each process, and multiple protection mechanisms such as sound and light alarms and interlocking shutdowns are used to ensure safe and reliable production operation.
