Abstract (en)

[origin: DE19831388A1] A liquid material in a heatable mould is solidified in an oriented manner using of a cooling unit. To control the motion of the solidification front, a cooling structure with at least one heat conduction element is introduced from below into at least one opening in a block (13) next to the mould base. The apparatus includes a cooling unit with a cooling structure (25) with at least one heat conduction element (10) which can be introduced using a drive mechanism (18) into at least one opening (17, 13a) in the block (13) next to the mould base.
