About Us
Our foundry was established
in 1969 and we are in the field of manufacturing quality Grey Iron
Castings in the grades of GF 300 and also grades incorporating Chromium,
Molybdenum and Vanadium additions. Our manufacturing capacity is
about 300 tonnes/month. We mainly supply castings including grey iron casting for machine tools, die tools and other engineering industries.
We are also specialists in
the manufacture of one-off single piece castings from 'Polystyrene
Patterns' especially for die tools, machine tools, etc. We can cast
castings up to 8 tonnes per piece. One of our main strengths is
delivery of quality castings including grey iron casting as per mutually agreed schedules, provided
the customer also reciprocates by timely honouring of their commitments.
We are classified as a 'Medium
Scale Industry' and a private limited company. The day-to-day
management is supervised by the Managing Director and Chief Executive,
and the foundry technical operations by the Works Manager. We have
around 78 full-time employees.
Our main melting unit is a 42"
cupola with a divided and oxygen enriched blast. All incoming ferrous
raw materials like pig iron, ferrous scrap, etc. are analyzed for their
composition. Based on this analysis, we decide on a particular charge
composition. Input to the cupola is fully weighed which enables us to
achieve the required composition in the liquid metal.
The moulding process is hand
moulding. We use either sodium silicate CO2 gas process or No Bake
process for moulds depending on customer preference. We mainly use No
Bake process for core making.
We have a dedicated group of staff
and workmen to achieve quality output. We have a small chemical
laboratory for checking the chemical analysis. We use outside testing
laboratory facilities for checking the mechanical properties like
tensile strength, micro structure, etc., as required for our grey iron casting, etc. Hardness is
checked on the casting using a Pouldi hardness tester.
Mostly, customers supply the
patterns to us and the onus of the dimensional accuracy of the
equipment lies with them. If required, we can also arrange for the
pattern equipments from our sub contractors.
We also have a heavy machine shop
to undertake both proof machining and full machining of
components. We have obtained ISO quality system
certification.

our process facilities and inspection facilities.
