MOLD, BLOW MOLDED PRODUCT, AND MOLDING METHOD

摘要

In order to provide a mold of a shape which has been designed to take into account the deformation occurring during the cooling process, the mold cavity is formed so that the external volume of a molded product obtained by blow molding in this cavity ultimately shrinks by a prescribed percentage of the volume of the mold cavity, and so that in the region of maximum shrinkage the external size of the body portion of the molded product shrinks by a prescribed percentage of the size of the corresponding portion of the mold cavity.
