The core package casting process, where the entire sand mould consists of single sand
cores, was industrially applied first in 1970 using low pressure filling by means of an
electromagnetic pump. Due to low productivity, the process was restricted to low volume
series. However, the increasing interest in the outstanding dimensional quality and possible
complexity of the castings led to further developments and thus, (e.g.) the Core Package
System (CPS ® ) has become an established casting process for the volume production of
engine blocks within a short period of time.
In the following screens, the process and design features of the core package
casting process are described:
