In this core making facility, the core requirement for two complete siamese CRANKCASE/BARREL packages and the corresponding WATER JACKET / SLAB assembly is produced on three core machines at the nominal rate of 75 cycles/h (corresponding to 300 cylinder block castings).

Combining a compact layout with high degree of automation and great flexibility of operation, the facility produces cores for a wide range of motor blocks, including several different single and siamese 4-cylinder blocks for major automotive Customers.

The CRANKCASE/BARREL and the FRONT/REAR cores are produced on two 60-liter core machines featuring automatic core de-finning upon ejection from the upper core box into a core de-finning/removal fixture.

The cores are then placed on an assembly turntable where the package is automatically bonded by shooting and gassing a sand bolt through the stacked-up cores. This method does not require special tooling and has proved to be both effective and cost-efficient.

The package is then picked-off by robot, dipped into a coating tank, and deposited on the same pallet as the water jacket and slab core assemblies.

The WATER JACKET and SLAB cores are produced on one 40-liter core machine, automatically de-finned, picked-off by robot, and deposited onto a turntable for automatic assembly by screwing.

The same robot then picks-off the assembled kits and deposits them on a special coating station designed to sink the cores into the wash.
