Dimensional changes or sharp bends in the casting result in different wall thicknesses within the cast component
Problems arise during the heat treatment process of the dies.
Creation of stress accumulation points in the dies during heat treatment and casting process.
The larger the shapes and the more intense the wall thickness differences of the inserts, the more necessary it is to use hot-work steels with
improved toughness properties.
