A method of making a sand mold includes filling sand in a flask with a pattern and its vibration compaction to the maximum density. During vibration compaction the presence of changes in the density of sand is determined and upon termination of the change the vibration compaction is stopped. In particular, the presence of changes in the density of sand is determined by reducing sand level in a casting box, and in the area of manufacturing molds in the sand facing of continuously moving mold the presence of changes in the density of sand is determined continuously.
