A method for producing a cast-iron cylinder liner for piston engines in which a metal chill mold (1) is used which has a tubular mold cavity (2) lined with a layer of a hardening molding material or green sand (3). The melt (7) is introduced into the mold cavity from above in such a manner that the cooling effect from the chill mold and the lining provides a frontage of solidification directed upwardly from the bottom.
