Abstract

In sand mould making by squeeze action, squeezing of the sand in a mould box is carried out at the pattern side after squeezing from the opposite side has been completed to a distance (nearly) equal to the full stroke of the entire squeezing operation. Pref. the mould box comprises a supplementary mould box mounted on a main mould box.
