Stages Of Investment Casting Process

Application
Investment Casting process is accepted worldwide as one of the most efficient & economical manufacturing technology for precision & intricately shaped parts. It has a lot of advantages viz.

Intricacy Shapes Any Intricate shape can be cast eliminating the necessity for machining of fabricating from assembly of different components.

Dimensional Accuracy Parts can be cast to very close tolerances which eliminates most of the machining and this gives it an enormous advantage over Sand Castings & Forgings.

Superior Surface Finish Eliminates or minimises need for Finishing operations.

Closer Control of Metallurgical Characteristics & wider range of Alloys- Ferrous & Non-Ferrous Ensures desired chemical composition & Mechanical properties & wide range of Alloys like Ferrous & Non-Ferrous.

Faster & cheaper development of new components This is ensured by inhouse Tool Room facilities & soft Metal Die Technology.

Batch Sizes Parts can be produced in exact replicas in small or large economic batch sizes.
