Airflow squeeze molding was invented in the late 70s of the 20th century in Japan and since the early 80s it has been predominantly used for production of horizontal box molds in green sand molding processes. During the first cycle of the mold production process, the mold box is filled with molding material. The filling of the sand into the mold compartment formed by means of the pattern plate / pattern plate carrier, mold box, and filling frame takes place via a bin discharge conveyor or with the help of a dosing unit using the gravity effect. Then, the compaction head is positioned above the mold compartment. By lifting the machine table, the mold compartment is hermetically sealed. Subsequently, the mold is compacted by briefly subjecting the molding material tu compressed air. During this sequence, the air flows through the molding material and is vented through the nozzles in the pattern plate and/or directly in the pattern and on through the pattern plate carrier. Subsequently, the mold is finally compacted by squeezing. The process sequence is illustrated
