How to calculate the weight of sand mold？

In the initial design planning of the automated casting molding line, we need to calculate the weight of each sand mold to determine the hourly sand mixing and processing capacity of the sand processing system that is paired with the automated molding machine! For example, after compaction by a casting molding machine, the size of the sand mold formed is 600mm x 700mm, and the height of the sand mold is 500mm. We can use 0.6m (length) x 0.7m (width) x 0.5m (height) x 1250kg/m3 (sand mold density): that is, the weight of each sand mold is 0.6 x 0.7x 0.5 x 1250=262.5kg;

If the automated casting molding machine can complete the molding of 90 sand molds per hour, then the matched casting sand automation processing line needs to complete the mixing of 90 x 262.5kg=23625kg of molding sand per hour, which means a processing capacity of over 23T per hour.
