ABSTRACT:
A device for vibration and realization of compaction pressure suitable for manufacture of sand casting molds in a flask which comprises two plates of which one plate carries a cylinder wall and forms a cylinder top and the other plate forms a piston, the space between these plates being substantially of the same diameter of the plate which forms the piston and being connected to a steplessly variable pressure medium source so that the compaction pressure and vibration amplitude are steplessly adjustable.
