INVESTMENT CASTING
Investment casting often known as lost wax process, is regarded as a precision
casting process to fabricate near to net-shaped metal parts from almost any
metal and alloys.
We produce precision investment castings to accommodate all your unique
needs from prototype, small order quantities, to high quantity runs. We
are matching all International quality standards as like ASTM, AISI, DIN, GOST,
JIS, B.S, SAE, IS of carbon steel, stainless steel, super alloy like Hastalloy,
Stellite, Monel etc.
INVESTMENT CASTING THE PROCESS
-
Formation of wax patterns are done by
injecting wax in to the moulds on automatic cycle control presses to ensure
the consistent production of wax pattern in controlled
atmosphere. Patterns are then assembled in a form of a tree.
-
Shelling process is to provide hard
ceramic coating on wax tree by applying number of ceramic coats depending upon
shape, size & weight of the article in controlled atmosphere.
-
Shells are stored in controlled
atmosphere between each coats for drying of coated ceramic.
-
Melting
is done in a line isolated
medium frequency Induction Melting Furnace to ensure precise control over the mental
composition.
-
Well equipped Laboratory
to test and ensure accurate composition of alloy castings after pouring.
-
Finishing of cast articles are done by
knockout machines, cutting machines grinding machines, Shot blasting
machines depending up on the job handled.
-
Heat treatment of casting is done to get various properties by different
processes like Normalizing, Carburizing, Salt Bath, Gas Carburizing,
Nitrading, Annealing etc.
INVESTMENT CASTING TECHNOLOGY
Our technology is totally indigenous and in a modified form, from that of the
existing recent developed technologies used in major developing countries. Synthetic Wax, used for patterns with water
- soluble wax / urea / ceramic for core. Water based colloidal silica is used with Zicron, Zirconium dioxide,
Fused Siliminate, Fused Silica, and Alluminate Silicates depending on the size, shape, metal selected.
INVESTMENT CASTING TOOLS DESIGN
-
In house well equipped design tool room to manufacture
multi-cavity complex dies.
-
Associations with tool rooms equipped with
CNC wire cut, spark
erosion, 3D pantograph machine.
MELTING & ALLOY MAKING
-
Melting department equipped with
'Line isolated medium frequency Induction Melting furnace', supplied by
world leading company M/s Inductotherm.
-
The melting
and pouring operation is
done under strict supervision of the melting department supervisor.
-
We
make metals/alloys which caters to specific customers needs.
-
In house laboratory to
test accurate composition of alloy casting.
INVESTMENT CASTING-QUALITY CONTROL
-
We perform and document an initial sample inspection
report of dimensions and metallurgy.
-
We complete all critical inspection
required by our customers prior to shipment.
-
We comply with the standards
as like ASTM,
AISI, DIN, GOST, JIS, BS, SAE and IS .
-
Our quality Assurance Laboratory includes Modern facilities and qualified technicians.
A Single spark optical emission spectrometer with 28 channels has been
installed for precise measurement of chemical composition of all alloys.
-
We perform
physical & hardness test in our in house laboratory and
perform fluorescent penetration
inspection & ultrasonography & radiography of our
casting with our associated laboratories.
