The decision to comprehensively renew the existing production system, set the task to the foundry Cirex from Almelo to accomplish a series of process-related improvements. VIRO was intensively involved in the development of concepts and designed the whole new cooling system, in which the casting and the cooling takes place. This increases capacity and improves efficiency. Due to the intensive and excellent cooperation between several parties, this assignment resulted in a successful project for Cirex. Cirex allocated the detailed process analysis and optimization on which VIRO developed a solution which effected, that casting takes place no longer outside, but now in the cooling system. In the old installation, the molds were taken over by a manipulator from the oven to the casting position, where the casting took place. After casting, the molds were parked in a rotation table for cooling. Now the empty molds are taken out of the oven and immediately set to a vacancy in the rotation table. The manipulator has been replaced by a programmable robot. Then the casting of a second programmable robot takes place, which operates the casting ladle. The carousel has been expanded to 36 positions and the hydraulic drive of the hood which is positioned over the molds to cool, then using a nitrogen atmosphere, was converted to pneumatics.
