Sand casting technology

Sand casting is the most widely used metal casting process in manufacturing. It is used to make large parts (typically steel and iron, but also Bronze, Brass, Aluminum). Sand castings can range in size from very small to extremely large. Some examples of items manufactured in modern industry by sand casting processes are engine blocks, machine tool bases, cylinder heads, pump housings, valve and etc..
