To popularize the isostatic pressing technology of explosive charge from high-end special industry to conventional ammo industry, the technological characteristics and method of molding of the explosive by isostatic pressing were outlined. The current research situation of the isostatic pressing technology of explosive charge was summarized. Through analysis, considering that the isostatic pressing technology of explosive charge is an important technology way to enhance the energy level and the launching safety of the explosives charge synchronously. Vacuumizing the materials before isostatic pressing charging or in the molding process of the explosive is favourable to improve the compactness and inner qualities of the explosives. Suggestions on the application of isostatic pressing technology of explosive charge in conventional ammo were presented for the conventional warhead development requirements of the high quality technology of explosive charge. 
