| Ductile
and Grey iron castings are produced in DISAMATIC
high pressure flaskless greensand moulding lines. Two
of the three lines are exclusively dedicated for ductile iron production.
In DISAMATIC process, moulds are produced by squeezing sand at high
pressure and then moved in a string without displacement by automatic
mould conveyors through pouring and cooling zones. Pouring of treated
metal is by automated pouring furnace and tundishes. After in-mould
cooling, the castings are separated from sand by tumbling in a cooling
drum. The transportation of castings and sand are entirely by automated
conveyor systems. |
