Abstract

A core for casting a valve housing includes at least one first core part which is additively produced, and at least one second core part which is produced without using additive production. The at least one first core part represents at least one pressure chamber or at least one pressure medium channel of the housing which is configured to provide a fluidic connection of a pressure medium source to a pressure medium consumer when the housing is formed using the core. At least one frame-shaped core holder is formed by a first of the at least one second core part when the housing is formed using the core.
