Abstract: In this paper, several researches on the airtightness test of composite forming molds are conducted in the autoclave by static pressure method. Focusing on the unstable airtight test results for composite forming molds, the key factors affecting the airtightness of composite forming molds are analyzed based on the principle of the vacuum static boosting method. The airtightness test system of composite forming molds are optimized. Finally, the optimized systems are proved to be very stable through airtightness tests which based on the air tightness test standard of composite forming molds.
