Shell Moulding Technology and Products


Shell moulding is a technology used to produce castings on the net near shape concept.

The particular system of production of a thin rigid shell is able to obtain geometry on casting with restricted tolerance, finished and smoothness surface and complex shape

Much more than a system to shape the geometry


This system is providing a number of other advantages. Further the first possibility to use the geometrical quality of a shell moulded part, the other points focus on the thermic and mechanical characteristics of the shell mould. These characteristics are the bases for a reliable and advanced casting part.

Material produced

  • Gray Iron
  • Compacted Graphite Iron
  • Ductile Iron
  • Alloyed Cast Iron
  • Carbon Steel

Compacted Graphite Iron

Compacted Graphite Iron (CGI) is the better compromise that the metallurgy of iron is able today to offer for mechanical solution.

  • cgiMicrostructureElevated mechanical performance in reference to gray iron;
  • Elevated machinability in reference to ductile iron;
  • Better castability in reference to gray and ductile iron;
