Molten metal is then poured into this cavity. When the metal has cooled down and solidified, the investment is broken away, and the core is removed from inside the cast. The process is, of course, much more complex than this simple outline suggests. Care has to be taken to suspend the core within the mold by means of metal pins, and a structure of channels must be made in the mold that will enable the metal to reach all parts of the cavity and permit the mold gases to escape. A considerable amount of filing and chasing of the cast is usually required after casting is completed.</span></span></span></span></span></span></span></p>
