Pneumatic hammers break the sand core in the first step by applying impact energy. The broken sand core is then crushed by high-frequency oscillating movements. This is done by crushing and breaking up the sand lumps on the casting wall. The removal of the moulding sand is achieved by vibration and a rotary movement of the casting.
