Abstract

Based on survey results of foreign samples, the authors have simulated primer and then calculating, designing and manufacturing of mold to compressure primer charge. Thereby, researching on technology (pressure, maintaining time of pressure) of manufacturing primer charges by equipment, technology and materials available in the country. The results showed that: Optimal pressure is (55±2) MPa. Maintaining time of pressure is (5±0.5) seconds and Material is No.3 black powder will give required products with density (1.836±0.005) g/cm3 (require is not less than 1.823 g/cm3), diameter (25.15±0.02) mm (require is from 24.7 to 25.3 mm), thickness (5.01±0.01) mm (require is from 4.75 to 5.25 mm), mass (4.02±0.01) g (require is from 3.9 to 4.2 g), the surface is smooth and vibration test is not be cracked. The achieved research results are the basis for manufacture and application of primer charges for PT-8M.VN bullet in Vietnam.
