Abstract
A core box for producing casting cores having a core defining member made of a first material and defining a core molding cavity. A stream of molding substance is introduced into the core molding cavity when a core is molded. A core marker is made of a second material and is located in the core member in fluid communication with the cavity. The second material is more wear-resistant than the first material, being a non-deformable hard metal. The core marker is a shaped insert for defining a predetermined configuration of a casting core when a molding substance is introduced into the core molding cavity. The shaped insert is located at a position within the core molding cavity at which position high velocity flow or changing velocity flow of a stream of molding substance is intercepted.
