Sand core dryers use high-velocity air nozzles to improve energy efficiency by allowing a reduced oven temperature.
There are many factors involved in boosting productivity in sand casting operations, which typically have hundreds of process details to track and just as many variables to manage. In order to achieve highest throughput, these foundries must increase their rate of mold and core production, which means that the refractory coating — also known as a "mold wash" or "core wash" — on those products should be force-dried using a convection oven. These "sand core ...
