Shell core making. The benefits of shell cores include strength, high dimensional accuracy, excellent surface texture (100 AFS sand), and ease of removal in complied core assemblies. The surplus sand is also easier to remove, through heat treatment and other knockout processes, so that it can be recycled. The cold box process
Sand casting
In 1940, thermal sand reclamation was applied for molding and core sands. In 1952, the "Dprocess" was developed for making shell molds with fine, precoated sand. In 1953, the hotbox core sand process in which the cores are thermally cured was invented.

ATD has taken the worst of the worst, sometimes just a skeleton of a machine, and turned them back into core making work horses. We can incorporate new valves, new electrical system, replace missing components, refurbish worn items, add safety features, you NAME it and we can do it. Just take a look at the example below.
Sand Casting: Introduction
Core is a sand shape inserted into the mold to produce the internal features of the part such as holes or internal passages. Cores are placed in the cavity to form holes of the desired shapes. Core print is the region added to the pattern, core, or mold that is used to loe and support the core within the mold.
