Device for manufacturing cold-formed shaped forms of packaging out of a metal-plastic laminate where the said device contains a die with at least one die opening, in the die opening a stamp which may be driven by the die, and a retaining tool as a clamping facility that holds the laminate securely between the die and the clamping facility. The die and the retaining tool feature a facing edge region and the die, within the edge region, a shoulder region that surrounds the die opening, and the surface of the shoulder region lies 0.01 to 10 mm lower than the surface of the edge region of the die. Parts or in particular the whole of the shoulder region may be covered with a surface layer of low friction characteristics. The metal-plastic laminate is held clamped between the edge of the die and the edge of the retaining tool, and the stamp draws and stretches the part of the laminate in the region of the shoulder over the shoulder into the die opening.
Device for manufacturing cold-formed shaped forms of packaging out of a metal-plastic laminate having a metal layer of 8 to 150 microns thick, which comprises a device containing a die with a plurality of spaced die openings, and an edge region, a stamp movable into the die openings for deforming the laminate into said die openings, and a retainer tool as a clamping facility that holds the laminate securely between the die and the clamping facility, wherein the die and the retaining tool feature facing edge regions for clamping the laminate and inside the edge region of the die a shoulder region that surrounds the die openings, said shoulder region having a surface thereof and said die edge region having a surface thereof, and the surface of the shoulder region lies 0.01 to 10 mm lower than the surface of the edge region of the die, wherein the laminate is at least one of drawn and stretched in a sliding manner over the surface of the shoulder region.
Process for manufacturing cold-formed shaped forms of packaging out of a metal-plastic laminate having a metal layer of 8-150 microns thick, which comprises drawing the laminate using a die and retaining tool that hold the laminate in place and a stamp that deforms the laminate, wherein the die includes an edge region and a shoulder region both with surfaces thereof, said shoulder region being inside the edge of the die and surrounding a plurality of spaced die openings, and the die and the retaining tool feature facing edge regions, and holding the laminate, clamped and non-stretchable, between the edge of the die and the edge of the retaining tool, and drawing the laminate by the stamp over the shoulders of the die into said die openings, positioning the surface of the shoulder region 0.01 to 10 mm lower than the surface of the edge region of the die, and at least one of drawing and stretching the laminate in a sliding manner over the surface of the shoulder region.
