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.
- 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.
- Elevated mechanical performance in reference to gray iron;
- Elevated machinability in reference to ductile iron;
- Better castability in reference to gray and ductile iron;
