Main production machinery
of SIFL comprise closed die forging hammers of 10 Ton(16000 ft.lb) and 6Ton(10650 ft.lb)capacity.
Open die forgings requirements are met with a 1Ton clear space hammer.
Other supporting facilities include shot blasting machines,Pneumatic trimming press of 1000Ton and 500Ton capacity,
Hydraulic trimming press of 1200Ton capacity,
Billet shearing machines and a number of oilfired and electric furnaces for soaking as part of forging process.
There is a modern heat treatment plant equipped with number of furnaces both LDO fired and
electrically heated and a charging machine which takes care of loading and
unloading of heat treatment charges.
Our annual capacity is around 7500 Metric Tons.We manufacture closed die forgings in the weight range of 5
kg to 450 kg and open die forgings within 1kg to 75kg net weight per piece and ring rolling upto 650mmOD.
The company has got the capability to manufacture forgings out of Carbon steels,Alloy steels,Stainless steels,
Maraging steels,Aluminium alloys,Titanium alloys,Inconel(Su 718)etc
DIE DESIGN & DEVELOPMENT
SIFL's design & engineering capabilities
are ably backed by a well equipped Die Shop, set up along modern lines
with Double Spindle Copy Milling Machines, Electro Discharge
Machine(EDM), CNC Die Sinking Machine,CNC Turning Centre, Radial Drilling machines, Heavy Duty Plano miller,
Lathes, Tool & cutter grinders, etc. The design and development of the
die holds the key to blemish-free forgings.
At SIFL, we design both
single-impression and multi-impression dies. The design, of course, is
related to the forging drawings. And the decision on the type of die to be
used, is based on the specific requirement of each case. The care that
goes into the design of each die, also goes into the selection of raw
materials and the sequence of operation that follows. To facilitate
uninterrupted operations, SIFL is equipped with standby Power
Generators.
To keep pace with hi-tech developments,SIFL has
equipped with CAD,CAM facilities like AUTOCAD,DELCAM for three dimensional modeling
of Product, Die & Tool design etc, thereby minimising the
development cycle time .All these facilities have helped SIFL grow
quickly into a premier forging unit, capable of producing forgings
with close dimensional tolerances.
We are proud to say that various
products developed in SIFL is for the
first time in India.This includes Wheel Hub(BS-4L77 Aluminium Alloy-120kg) for sukhoi 30MKI Aircraft,Shock Strut Cylinder-Landing Gear-LCA Naval version(Maraging steel-390kg)
for HAL and Tee piece(Titanium Alloy-B381 Gr.5-300kg) for Nuclear Submarine by Defence.
FORGING & HEAT TREATMENT FACILITIES
The billets for forging are heated
in oil fired or electric furnaces, closely controlling the temperature to
reduce the scale formation and overheating so that the metallurgical
properties are ensured in the final product. In addition,
in-process inspection is carried out at all stages and 100% inspection for
visual defects after forging. The accepted forgings are duly heat treated to ensure its mechanical properties.
By providing heat treatment services in-house, SIFL is able to maintain
greater control over heat treating process. The facility comprise batch
furnaces both oil fired & electrical, continuous electrical heating
furnaces, solution treatment etc. to carry out annealing, normalising,
hardening, tempering, iso-thermal annealing, solution treatment etc or
other operations as specified by our customer. Close
temperature control and process monitoring with the help of temperature
recorders ensures uniform properties duly supported by evaluation of
metallurgical properties through representative test pieces.
TESTING/INSPECTION FACILITIES
Surface conditioning is done by shot
blasting/grinding and final inspection is carried out once again to ensure
quality requirements.Non-conformities are taken
care of by timely corrective and preventive action. Calibration of electrical furnaces of SIFL are done by NABL accredited laboratories like HAL,STIC(Cusat) etc.
SIFL has set up a
system of total quality control consisting of an array of state-of-the-art
speciality equipments where your products go through a series of rigorous
tests, the destructive test including tensile, jominy and impact testing,
wet analysis, carbon-sulphur determination, insitu metallography(where microstructure can be observed without destroying the job) and
non-destructive tests using Spectrometer, Microscope, Magnaflux crack detection, Die Penetrant,Ultrasonic flaw
detection etc.We are now equiped with a new digital ultrasonic flow detector which has got a range of 5mm to 5m in steel.
Setting and control of quality standards at all stages
right from the receipt of raw material to the finished product through
quality plan makes us deliver superior quality forgings with close
dimensional tolerances and metallurgical
properties.
