ABSTRACT:
A method and apparatus for reshaping a container body (e.g., a metal, drawn and ironed container body) utilizing multiple fluids is disclosed. One fluid applies a generally low fluid pressure to the surface to be reshaped, while the other fluid applies a generally high fluid impact pressure to the surface to reform the same by changing its shape. In one embodiment, the interior of a drawn and ironed container body is pressurized with an appropriate gas (e.g., air) and a nozzle is introduced into the interior of the container body to apply a concentrated force to the interior surface of the container body with a high velocity liquid stream (e.g., water).
