Abstract

When compressing a part, stress concentrations are prevented when it is removed from the mold by lowering an insert so as to release the top of a fine, flexible inner tube in such a way that it can expand in the location where the part will be removed from the mold, and can partially release the inner stresses in the part, in the area of the portion which has been removed from the mold.
