R. SCHEUCHL GmbH’S Shake Champion decoring machines SC 420 is suitable for decoring sand castings and diecastings ranging from 1 – 160 kg. The maximum dimensions of workpieces that can be decored are roughly 1.120 920 450 mm. Based on a high-frequency vertical oscillation with amplitudes up to 36 mm, the casting is exposed to vertical oscillation. The broken sand core is dashed upward and down against the casting wall, disintegrating the sand. Loose sand is ejected by the oscillation from the openings of the castings and discharged over the integrated sand conveyor system from the machine.
