ABSTRACT:
Method for selectively rotationally molding an industrial drum in either a closed-head configuration or an open-head configuration within a mold constructed for selective modification to accomplish molding of the drum in either selected configuration by inserting or deleting a separator between a first mold cavity for forming the body of the drum and a further mold cavity for forming the head of the drum, the further mold cavity being selected from alternate second and third mold cavities, such that both the body and the head are rotationally molded simultaneously within the mold during molding of either configuration of the industrial drum.
