For irregular shape, such as the workpiece to form a virtual wave-shaped wall, or complex special-shaped workpiece, the choice of explosive forming, simply put, is to use the internal and external mold has been unable to process components, the main reasons are three points:

1 , is processed within the mold can't take out,

2, and the outer wall of artifacts have several is not in the same plane, mould pressing stress non-uniform fracture is inevitable,

3, stretching ratio is too high, the explosion forming can solve the above difficulties, only need to strengthen external mold, mold processing into workpiece shape, general external mold artifacts based on complexity into several disc, and already has been formed after take out the artifacts
