Abstract: Helium mass spectrum leak detecting technology was introduced, and fabrication process of composite molding mould and vacuum integrity detecting methods for composite molding mould were discussed. The necessity of the application of helium mass spectrum leak detecting technology in composite molding mould was analyzed.This method had advantages in accuracy, economy, cycle, and so on. So it had a great meaning of applying helium mass spectrum leak detecting technology on vacuum integrity detecting test of composite molding mould. The application of helium mass spectrum leak detecting technology in domestic and foreign composite molding mould was introduced, the leak detecting system was designed, and some research and practices were developed. Also, some attentions during leak detecting test were summarized.

Key words: helium mass spectrum, leak detection, composite, mould
