We have equipped with a cold box core making machine. The cold box technology has been widely used in automobile, tractor, aircraft, machine tool, pump and other industries because of its high production efficiency, energy saving, high dimensional accuracy of sand core, low gas generation, long life of core box, small deformation, bright and clean casting surface, high dimensional accuracy (up to CT7), and good collapsibility of sand core after pouring.
