For explosion network with the features of small diameter, large aspect ratio, and many degrees of corners, the syringe for plastic explosives and the squeeze charge process by way of repeated sections were designed. HMX/CL-20-based plastic explosives as the injected booster were made. Its charge density and density uniformity in the grooves were examined. The linear propagation velocity and corner dissemination capability of detonation wave and linear critical size were studied in 0.5 mm × 0.5mm -1 mm × 1 mm grooves. The results show that the squeeze charge process and HMX/CL-20-based explosives are feasible for explosion network. The average density of the charge is about 1.45 g/cm3 and uniform. The shaping of dynamite is good. The detonation wave has a high reliability of propagation in over 0.5 mm × 0.5 mm grooves. The linear propagation velocity of detonation wave and the maximum explosion corner turning are 7276 m/s and 150° for 1 mm × 1 mm grooves, 7131 m/s and over 150° for 0.8 mm × 0.8 mm grooves, 7013 m/s and about 135° for 0.6 mm × 0.6 mm groove and 6906 m/s and about 135° for 0.5 mm × 0.5 mm groove. The linear critical size is between 0. 3mm × 0.3 mm and 0.4 mm × 0.4 mm.
