The work aims to design a bullet plastic packaging system based on servo process control to improve the protection and reliability of the bullet. A new bullet packaging system was formed by combining the servo process control, automatic bullet packaging system and plastic packaging technology. As a result, the bullet plastic packaging system based on servo process control had high positioning accuracy. The plastic packaging size and thickness were controlled at 0.01 mm. After nine million rounds of bullets ran packaging validation, a new bullet packaging system was built. The bullet plastic packaging system based on servo process control reaches the requirements of bullet packaging process, and it is reliable and stable, which reduces the number of operating personnel and realizes the man-machine isolation.
