Process for manufacturing cold formed shaped packaging having at least one recess made from a metal-plastic laminate 20. Examples of such shaped forms of packaging are the base parts of push-through packs or blister packs. The process is such that the laminate 20 is held between a retaining tool 5 and a die 1. The die 1 exhibits at least one opening 8 and a stamping tool 6 is driven into the die opening 8 causing the laminate to be shape-formed into the said packaging and, correspondingly, exhibiting one or more recesses. The die 1 and the retaining tool 5 exhibit facing edge regions 11,12, and within the edge region 11 the die 1 exhibits a shoulder region 13 that surrounds the die opening 8 or openings 8. The surface of the shoulder region 13 lies 0.01 to 10 mm lower than the surface of the edge region 11 of the die 1. A first stamping tool with low-friction shape-forming surface forms the metal-plastic laminate in one or more steps down to 100% of the final depth of the recess and subsequently the same or a second stamping tool 6 likewise with low-friction shape-forming surface effects the final forming of the pre-formed laminate 20 in one or more steps to at least 100% of the final depth of the recess.
Process for manufacturing cold-formed shaped forms of packaging with at least one recess from a metal plastic-laminate, which comprises:
Device for manufacturing cold-formed shaped forms of packaging with at least one recess from a metal plastic-laminate in which the laminate is held between a retaining tool and a die exhibiting at least one opening, and in one or more steps stamping tools with low-friction shape-forming surfaces are driven into the die openings causing the laminate to be formed into a shaped form of packaging featuring one or more recesses, which comprises:
