Tooling for Shell Mould Casting

Tooling for metal casting processes varies. From sand castings with individual moulds and cores to shell moulds with a variety of pattern plates, core boxes, cavities, ejection systems, and gates. When all of these components come together, the shell mould casting process allows the foundry to precisely produce the required dimensions, whether it’s doing a run of 100 or 100,000 parts. There are a variety of metal forming techniques that can be used to create the mould tooling for shell mould casting, and the best process is determined by the conditions of the foundry.
