The Drop Hammer and Ring Rolling Lines are equipped with
necessary quality control equipment and stage inspection
as per Control Plan is carried out at regular intervals.
We are highly conscious of the critical areas where our
products are used. Thus, our quality control works inseparably
with our production unit and is responsible for product
quality. We have a central documentation cell to record
the history of each product, along with evidential test
results, stage inspection reports, manufacturer's test certificates
which are compiled into a data book.
We have a fully equipped chemical testing lab for carrying
out accurate quantitative analysis of common elements like
C, Mn, Si, S, P, Cr, Ni, Mo etc using an Optical Emission
Spectrometer. Mechanical Properties like Tensile Strength,
Yield Strength, Reduction of Area, % Elongation, Charpy
Test is also provided for individual heat from qualified
independent laboratories.
Crack Detection/NDT of individual forging is carried out
by Magnetic Crack detection machine, where specified by
the customer. Ultrasonic testing if required, can be provided
from a third party lab. In addition to above, we also have
an Eddy Current sorter.
We are ISO/TS 16949:2002 certified by
