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.

In 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.
