The Shell Casting Process, leveraging Resin Sand and Coated Sand, is a prominent casting technology in industrial manufacturing. Initially, resin sand or coated sand is prepared. The sand is then brought into contact with a heated metal pattern, which enables the formation of a thin yet robust shell mold. After the shell mold is fabricated, it is assembled, and molten metal (such as cast iron, carbon steel, or alloy steel) is poured into the mold cavity. Once the metal solidifies and cools, the mold is stripped away, resulting in the cast component. This process is characterized by its ability to produce castings with favorable dimensional precision and surface quality, making it ideal for the large - scale production of small to medium - sized cast parts.

Lost foam casting uses an expandable polystyrene pattern. First, coat the pattern with refractory coating and dry it. Then, place it in a flask and fill with compacted sand. Pour molten metal, which vaporizes the pattern, filling the cavity. After solidification and cooling, remove sand to get the cast part. It enables complex shapes, low tooling costs, and less post-processing.

A lost foam casting line automates the process for efficient, high-quality production. It begins with making expandable polystyrene patterns. The patterns are coated with a refractory layer, dried, and placed in sand flasks. Dry sand is vibrated around them to form a mold. Molten metal is poured, vaporizing the patterns and filling the cavity. After solidification, sand is removed, and castings are cleaned. This line allows for complex geometries, lowers tooling costs, and streamlines the manufacturing of metal parts.
