Desanding of Aluminium Castings
The Shake Champion Series – Reliable and Effective Decoring of Castings
Process description:
The sand core is first broken up by impact energy and thus prepared for the subsequent vibration decoring. A high-frequency vertical vibration direction throws sand lumps against the casting wall with high energy, effectively breaking them up. This vibration direction makes it possible to skip over ribs in cavities. A resulting sand-air mixture is transported out of the casting by the high-frequency vibration.
For parts with large cavities, these can be rotated into the required positions by means of a rotation unit. The loose sand then flows out, while the vibration direction changes with the rotation angle.
Suitable types of castings:
- Crankcases
- Cylinder heads
- Chassis parts
- Pump housings
- Oil pans
Advantages of the Shake Champion plants:
- Low investment and operating costs
- Reduction of decoring scrap
- Simple operation
- Flexible casting fixture
- Reduction of decoring time through high performance
- Robust design
- Integrated sand guiding technology
- Direct sand discharge into box, conveyor belt or vibrating conveyor trough
- Optional: integrated hammers for core breaking
