The LORAMENDI KEY CORE system was developed to satisfy the demand of the automotive industry to produce cylinder blocks with thin walls, reduced casting weights, better dimensional accuracy, lower reject rates, and lower machining costs.
Before the KEY CORE ® system was implemented, foundries were either setting loose cores in moulds or using foreign objects to join the cores. These processes, in most cases, were not living up to the latest requirements for dimensional accuracy and high production rates.

The KEY CORE ® process is one of the few processes that fulfills all necessary requirements. The individual crankcase and end cores are produced using a cold box process, then set in a fixture and locked together by blowing a KEY-CORE ® in the special KEY-CORE ® Machine using the same cold box process.
