5) we conclude that to achieve a good dimensional accuracy and low contraction of the wax pattern, it is recommended a casting temperature as close to the melting point temperature and also a mould preheating temperature as low.
However, the difficulty in this approach is that it's impossible to control the exact way in which the beads are distributed over the wax pattern, so every casting is slightly different.
