manufacturers worldwide. It was not difficult for
the rough castings and machining. However, you have
to keep the good surface quality and good dimensions
for installation. The suitable casting process was
resin sand casting, however, some parts were small,
so green sand casting process will be necessary.
Therefore, the foundry should have very fine green
sand to make the small parts.
As for the patterns, Dandong Foundry
suggested to use the resin patterns, which has good
lifetime, and lower costs than metal patterns.
