The modern full-automatic lowering moulding machine works with a lathe for pattern making to produce cope and drag moulder forms. The compaction of the moulding sand is effected by means of SEIATSU-airflow-press-forming method: an airflow with overpressure comes through the moulding sand from the form back towards the pattern and leaks through nozzles in the pattern plate and the pattern plate girder. The final compaction is effected by hydraulic final pressure from the top with a multi-piston squeeze head.

The result is an even and high-compacted form bale. An assumption for an accurate to measurement and precise casting with a clear surface.
