At every stage of productions, Quality Control measure is
strictly followed such as:
Accepted raw materials are mixed in definite proportions and
ground in the ball mills. Before discharging the Ball Mill,
the slurry is tested for required fineness etc. The slurry is
stored in underground blunger and filter cakes are taken out
which may be termed as Starting Material.
The starting material (filter cakes) goes for different types
b) Semi-dry Pressing
c) Vacuum Extrusion and
d) Slip Casting.
formed components are dried, finished and in many cases
Next stage is firing/baking in Tunnel Furnace/Shuttle Furnace
depending on the material characteristics. The fired products
are 100% inspected for quality, dimension and any other
routine tests required.
The inspected components are either packed or further machined
to close tolerance of upto +/- 0.01 mm.
