Abstract
A method and apparatus for blow molding a case for housing an object, such as a tool, is disclosed generally comprising first and second mold portions located adjacent each other to create separate cavities for forming base and lid portions of a case and a punch for each portion corresponding to the outline of an object. In certain embodiments, the punch protrudes into the cavity during blow molding to create a sidewall to facilitate a press fit. In some embodiments, additional punches and/or recesses are provided to produce additional apertures or flanges in the walls of the tool case.
