Abstract
A method for producing a casting core for manufacturing cylinder heads including the following steps: producing at least one core component, by a constructive method, with a contour for the formation of internal contours of a first cylinder head producing at least one further core component, by a constructive method, with a contour for the formation of internal contours of a further cylinder head; producing at least one sprue core component for feeding the molten mass during the casting method; and joining the two core components to the sprue core component in an opposing orientation.
