Dandong Foundry owned
many sets of single-station and double-station
core-making machines. We adopt advanced shell core
tech besides hot box, especially for key parts. It
improves the smoothness and dimensional precision,
reduces the machining, increases efficiency of
labor, decreases material cost.
China, most of foundries mainly use this
shell molding line to make grey iron and ductile iron castings.
However, we cooperated with local steel foundries to
produce steel castings by this process. In this way,
we could produce small steel castings by much lower
prices than lost wax investment casting processes.
