Forming of thin wall spherical parts is always a difficult point of sheet metal working technology.This paper presentsa new method for the large extra thin wall spherical parts forming technology. Non die explosive forming method has successfully solved the forming of thin wall and extra thin wall spherical parts. Through various engineering practical implementations, the design principles of the shell structures and calculation formula of charge size have been verified, thus uncovering the broad perspectives of this new method.
