Freezing & Knock Out
A. After pouring of metal at 1420 – 1480 Degree C, the mold is allowed to cooled down for 1 and half hour time.
B. Once the mold box reaches to the knock out station, the poured mold boxes are knocked out on vibratory knock out system where the separation of casting and sand is initially takes place. The castings are dragged out of vibratory knock out and separated sand will move to hopper through shaker and magnetic separator which allows clean sand entry in hopper.
