Abstract
A core for use in a die casting process has a wood fiber material as a main ingredient. The core can be disintegrated by exerting an external force subsequent to the die casting process. The core can also be disintegrated by applying a softening agent to soften it subsequent to the die casting process. Further, the core can be made up of a stack of paper layers that are peelably removable from each other.
