Assembling of patterns onto a casting unit (Tree)
Covering of trees with refractory material ( Shelling)
Dewaxing of Ceramic Shells
Sintering of shells
Pouring the required Metal ino shells.
Removal of Ceramic, cut-off, grinding of ingates, sand blasting, heat treatment.
Surface treatments like pickling, passivating, mechanical & electro polishing, hot dip galvanising etc.
Final Inspection
Packing & Despatch.

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.
