Cold box process

IIn the core package and stacking process, the entire geometry of the mold is formed by sand cores. The individual cores are put together to form a package or stack. Küttner takes care of the complete handling of these packages/stacks.

Küttner takes care of the backfilling with sand to stabilize the packages, the automatic pourin and subsequent cooling. After cooling, the backfilled sand is removed. Shake out conveyors are separating casting and sand and pre crush the core lumps. Hereinafter, the sand is reclaimed by crushing, screening, classifying and cooling, before taking back into the cycle. The casting handling is solved traditionally with vibrating conveyors with mass compensation from Küttner Schwingtechnik.
