Answer / anil kamat
Investment castings are similar to sand casting except that
intricate shapes which require to be done in a single piece
mould without ireggularities are done using this method. In
this the pattern is made using wax and then the the mould
is filled with sand around the wax pattern and the the
mould is baked untill the moisture is removed and the wax
evaporates and the cavity is formed . Then the molten metal
is poured into the cavity to get the desired shaped casting.
