Reducing Sand Casting Core Defects | EMI White Paper …
Capacities of very small to extremely large cores can be considered with the No Bake process. The core blowing process for the no bake cores typically does not allow for the repeated blowing of the sand in discharge magazine, as in cold box or other process. After blowing, the remaining sand is discharged and not re-purposed.
