1. A method for producing a container, the method comprising:
- providing a die that includes a die bottom part, a die top part, a flexible element extending between the die bottom part to define a die outlet between the flexible element and the die bottom part, outer slides arranged laterally on the die, a blocking slide arranged below the flexible element and which is moveable in a vertical direction relative to the die outlet, and a plurality of adjustment bolts connected to the flexible element and which are adjustably moveable, the adjustment bolts including outer adjustment bolts and middle adjustment bolts arranged between the outer adjustment bolts;
producing a first structural part and a second structural part, each composed of an extrusion material, by;
initiating an extrusion process for the extrusion material;
forming, during the extrusion, a seal at lateral regions of the die by pressing only the outer adjustment bolts downward to thereby press the flexible element against the lateral slides without adjusting the middle adjustment bolts;
controlling, after forming the seal and during extrusion, the thickness of the extrusion material in a longitudinal direction and a transverse direction by adjusting only the middle adjustment bolts to thereby adjust a spatial distance between the flexible die element and the die bottom part;
cutting the extrusion material at the die outlet via the blocking slide; and
forming the container by connecting the first structural part and the second structural part at their respective circumferences.

Abstract
A die and a method for producing a structural part from hardenable material by way of a die. The die includes a die bottom part; a die top part; a die control unit; a flexible element extending along a lower edge of the die top part; and at least one adjusting bolt to adjust at least partially, via the die control unit, a spatial distance between the flexible element and the die bottom part during extrusion.
