how to calculate metal and sand ratio

Optimizing New Sand and Core Sand Additions in Foundry Green Sand

This includes varying the new- and core-sand dilution rate above and below recommended rates. The resulting data will be used to develop a simulation model to predict new and core sand requirements based on variables such as sand-to-metal ratio, amount and type of binder/cores used, and metal type.

The Importance of Mixer Calibration and Sand Analysis

Sand fines above 1% increase the amount of surface area the binder has to cover: Unless binder level is increased to compensate, cores and molds can be weak or friable. This may lead to casting defects such as burn-in, penetration, erosion, inclusions, and warpage. Depending on the sand-to-metal ratio, weak or friable molds could lead …
