Shake Out

Shake out is the process that de-sands the casting. After the part is cast it needs to be removed from the mold. This is done by placing the filled mold onto a agitated table that basically sifts the casting out of the sand. Once the aluminum is exposed and the remaining sand is removed the castings are placed into a cart where they await the next step. The sand that was used for the mold is routed back into out sand system where it will be used again to provide the mold for another part.

 

 

To de-core a permanent mold casting the part is fixed into a machine known as a rattler. The rattler vibrates the casting in order to break the core sand loose. The frequency of vibration must be tailored to the specific casting to achieve the optimal effect.
