Our Shell Core, Shell Moulding Foundry Infrastructure
Methoding
We use Simulation Software (Virtual pouring) which predicts the complete casting process including filling, solidification, cooling and allows the qualitative prediction of various properties of the cast product. We use this facility for methoding which saves actual shop trials and saves time in producing good castings at first go. The necessary method cards are made for every item and are preserved.
Radiography tests are carried out from reputed out source as per customers’ demand.
Moulding
We use Alpha set No-bake process for Moulding and have ‘SPAN ‘make line of Core Shooters with maximum core size 600 mm x 400mmx 400mm.
Melting
At the melting section, we have Inductotherm make Induction Furnace 500 kg Tri Track facility and also a 300 kg additional furnace. The melting section has online Carbon Silicon Analyzer and molten temperature measurement facility. On line display system with colour coding, is directly connected to the Lab Spectrometer for the fast transfer of data and ease of the operators.
Pouring System
- Car track with 30 Pallets for pouring of shell moulds
- Pouring ladle movement with the help of monorail
