EFA-S

The EFA-S is a machine for the automatic manufacture of large moulds at moderate moulding speeds. The mould boxes are pushed through the machine in line. A lifting table lifts the pattern plate, mould box and filling frame to a position underneath the opening of the sand dosing device, with which the mould space is filled with a controlled quantity of sand. The dosing device then moves in a shuttle movement to a position under the sand loading unit, and the crown of the press moves over the mould box. After compacting, the pattern is lowered. The machine can be equipped with a pattern shuttle trolley enabling cope and drag boxes to be produced in sequence. All functions for the manufacture of the moulds are controlled via a preset programme.

The single moulding automatic EFA-S is applied exclusively in automatic moulding lines.
