ABSTRACT An apparatus for forming container bodies utilizing a ram which is formed at least in part from a reinforced composite material (e.g., rams having a combination of structural components with at least one component being formed from an appropriate metal(s) and another component being formed from the composite material, rams formed entirely of the composite material). In one embodiment, the ram is incorporated into a bodymaker for drawn and ironed containers and includes first and second ram portions, the first ram portion being formed from an appropriate metal, the second ram portion being formed from the composite material. The first ram portion has first and second ends with an interconnecting portion therebetween such that a punch and ram drive assembly may be connected to such first and second ends, respectively. The second ram portion is thus positioned about the interconnecting portion to reduce the weight of the ram, as well as to allow for an improvement of the rigidity thereof. Consequently, the speed at which the ram may be advanced through the ironing rings may be increased and the deflection of the ram when passing therethrough may be reduced to enhance the container body formation process.
