METAL CONTAINER SUITABLE TO ACCOMMODATE A HEATING OR COOLING COMPONENT AND METHOD FOR MANUFACTURING IT

摘要

A method of producing a metal container from a low carbon steel strip or sheet (1) coated on at least one of its surfaces with a coherent laminated coating of a thermoplastic polymer material includes one or more redrawing stages which reduce the thickness of the side walls by a drawing/stretching operation, and a partial reverse redrawing stage to produce an initial internal chamber whose depth is produced by a reduction of its height. The initial internal chamber is then redrawn to produce two chambers of differing diameter and depth, the diameter of the initial chamber being decreased by the redraw operation and inserting by base reforming the final chamber with a new internal diameter and depth produced by a reduction in the container height.
