Sand casting method
With the sand casting technique, castings are produced by pouring liquid metal into a full-sized sand mould cavity. After cooling, the sand is removed, leaving the cast. Sand is characterised by high heat resistance, making it extremely suitable for materials with high melting temperatures.
