Apparatus and method for blow molding motive power battery cases

A motive power battery casing is blow molded in an oblong configuration of rectangular cross-section. The die is notched so as to create longitudinal ribs of relatively greater thickness of the molding material in a generally cylindrical parison. The casing mold is vented in the bottom at its corner...

Beschreibung
Zusammenfassung:	A motive power battery casing is blow molded in an oblong configuration of rectangular cross-section. The die is notched so as to create longitudinal ribs of relatively greater thickness of the molding material in a generally cylindrical parison. The casing mold is vented in the bottom at its corners to assure full development of the casing corners. The casing is formed with relatively thin side walls and a relatively thicker collar of the molding material near its top in order to provide sufficient strength for heat sealing at the top.
