Maruti Suzuki is one of India's leading automobile manufacturers and the market leader
in the car segment, both in terms of volume of vehicles sold and revenue earned. Until
recently, 18.28% of the company was owned by the Indian government, and 54.2% by
Suzuki of Japan. The Indian government held an initial public offering of 25% of the
company in June 2003. As of May 10, 2007, Govt. of India sold its complete share to
Indian financial institutions. With this, Govt. of India no longer has stake in Maruti
Maruti Udyog Limited (MUL) was established in February 1981, though the actual
production commenced in 1983 with the Maruti 800, based on the Suzuki Alto kei car
which at the time was the only modern car available in India, its' only competitors- the
Hindustan Ambassador and Premier Padmini were both around 25 years out of date at
that point. Through 2004, Maruti has produced over 5 Million vehicles. Maruti are sold in
India and various several other countries, depending upon export orders. Cars similar to
Maruti (but not manufactured by Maruti Udyog) are sold by Suzuki and manufactured in
Pakistan and other South Asian countries.
The company annually exports more than 50,000 cars and has an extremely large
domestic market in India selling over 730,000 cars annually. Maruti 800, till 2004, was
the India's largest selling compact car ever since it was launched in 1983. More than a
million units of this car have been sold worldwide so far. Currently, Maruti Alto tops the
sales charts and Maruti Swift is the largest selling in A2 segment.
Due to the large number of Maruti 800s sold in the Indian market, the term "Maruti" is
commonly used to refer to this compact car model. Till recently the term "Maruti", in
popular Indian culture, was associated to the Maruti 800 model.

Maruti is clearly an “employer of choice” for automotive engineers and young managers
from across the country. Nearly 75,000 people are employed directly by Maruti and its
The company vouches for customer satisfaction. For its sincere efforts it has been rated
(by customers)first in customer satisfaction among all car makers in India for nine years
in a row in annual survey by J D Power Asia Pacific.
Maruti Suzuki was born as a government company, with Suzuki as a minor partner to
make a people's car for middle class India. Over the years, the product range has
widened, ownership has changed hands and the customer has evolved. What remains
unchanged, then and now, is Maruti’s mission to motorize India.
BACKGROUND OF THE INDIAN AUTO INDUSTRY
Although the Indian car industry was established in the late forties, there was little
growth or technical progress, as passenger cars were given very low priority in the
scheme of Centralized Economic Planning. In the 1980s, the car industry was
undergoing technological stagnation and was characterized by low production volumes,
high cost and low productivity. The consumer had very little choice and the market was
selling just around 30,000 cars per year.
There was a clear need to provide a cost effective, reliable and quality car to the
customers. Maruti Suzuki India Limited was incorporated in such a scenario as a fully
owned Government Company on February 24, 1981 with a resolve to bring about
expansion and technological modernization, of the automobile sector. Thus MSIL, when
started was entrusted with the task of achieving the following policy objectives:
7. MARUTI SUZUKI INDIA LIMITED
Modernization of Indian Automobile Industry.
Production of Vehicles in large volumes, which was necessary for economic
Production of Fuel-efficient vehicles to conserve scarce resources.
Choice of product and collaborator
To achieve the above objectives, one of the foremost tasks before. Maruti Suzuki
India Limited was to determine the most suitable product mix and to select the
most suitable foreign partner who would be willing to accept MSIL ‘s
requirements in terms of product mix, technology transfer, and equality
participation and had the
required technological expertise and experience in producing high quality, reliable
and fuel efficient vehicles.
After extensive discussion with several major European and Japanese car
manufacturers, MUL chose Suzuki Motor Corporation (SMC) further increased its equity
holding to 50% in the year 1992, converting . Maruti Suzuki India Limited, into a Non-
Government Company with a total Equity base of Rs. 1322.92 million.
BACKGROUND OF SMC
SUZUKI was founded in 1909 as Suzuki Loom Manufacturing Company. It started
manufacturing motorcycles in 1952 and has become a world leader in the manufacture
of two-wheelers .SUZUKI started producing cars from 1955.Today it is Japan’s largest
manufacturers of small , fuel-efficient cars. At present the company’s name is SUZUKI

The press shop can be regarded as the starting point of the car manufacturing process.
Centrally located between weld 1, weld 2 and weld 3 supplies components to all the
three plants. The press shop has a batch production system whereas the plants have a
line production system. The press shop maintains an inventory of at least two days. The
weld shop as per the requirements picks the finished body parts from the press shop.
These may be divided as A, B and C. ‘A’ components are large outer components as for
example roof, door panels etc. These components are manufactured in the press shop
at Maruti due to design secrecy and huge investment requirements. ‘B’ and ‘C’
components are manufactured by joint ventures or bought from vendors.
Process flow of Press Shop activity :-
1. Currently Press Shop is producing sheet metal components for 8 running
models of Maruti Suzuki and one model of GM India - Tavera
2. The Blanking and stamping shop processes 10000 metric ton of steel / month

Steel coil is raw material used to make body sheet metal parts. These are
CRS coils made of mild steel having thickness from 0.65 mm to 0.8 mm &
weight from 1 ton to 4 tons.
Steel coils are received in bulk quantities from indigenous as well as
foreign suppliers in the ratio of 60 to 40 & stored at a centralized storage &
supplied to blank cutting areas as per plan
Steel coils are fed to Blanking & ROSL lines by overhead EOT cranes.
Sheet is first de-coiled , cleaned, oiled & fed to cutting or shearing areas of
blanking or ROSL lines.
31. MARUTI SUZUKI INDIA LIMITED
Coils are fed to blanking line & continuous supply of sheet to cutting dies
result in shaping of coils to plan blanks.
Blanks are cut by stamping or shearing process & are stacked one by one to
form large mass of blanks
These stacks of blanks are further sent to press machines for forming into
shape of body panels
Stack of blanks
32. MARUTI SUZUKI INDIA LIMITED
Blanks are supplied to press lines for pressing. Blanks are converted to body panels
by this process. Panels are stored in pallets which are supplied to Weld Shops for
making White Bodies.
33. MARUTI SUZUKI INDIA LIMITED
The body panels produced in the press shop and the other small components are joined
here to give the “white body” or “shell”. In a typical car body 1400 different components
are welded together. The weld shops have the following facilities.
Spot welding guns
Kawasaki welding robots
PROCESS OUTLINE: The shop has different lines for different models, each of, which
is further divided into three parts:
UNDER BODY: Here different underbody panels are welded together. These comprise
of rear underbody, central underbody, front engine room panel. These underbodies are
put on the conveyor and welded together to give the underbody.
MAIN BODY: As the body moves on, the conveyor roof and side body panels (prepared
on the sub lines) are welded to it to give the main body. The chassis number is punched
on the cowl top and it is welded to the front engine room panel.
WHITE BODY: The doors, hood and back door are attached on the main body with the
help of bolts and screws to make it a “white body”. The body is checked for dent, burr
and spatter and these defects are repaired. After inspection and repairs the body is
called WBOK. It is sent to the paint shop thereafter.
34. MARUTI SUZUKI INDIA LIMITED
In the paint shop following processes are carried out: -
There are five plants/units that provide a uniform painting over the white body coming
from the weld shop. In paint shop all the models are painted on the same line. The five
units are: -
Pre-treatment (PT): The body is thoroughly washed to remove the dirt and oil
scales. Then the body is treated with ZnPO4 (phosphating) to prevent corroding
of the body.
35. MARUTI SUZUKI INDIA LIMITED
ED coat: This is done by electric deposition method, at 240V-DC supply. After
applying the ED coat the body is baked in oven.
Sol-sealer and under coat: Here the left in the body (due to welding) are filled
with sol-sealer to provide water proofing. Under coat is done on the surface
above wheels to prevent damage of body in that portion.
Intermediate coat: This is done by spray-painting method using 10 Kawasaki
Robots. After applying the coat, the body is dried in the oven. Painting done is
basically an intermediate coating to provide base for the final coat.
Top coat: This is done by spray-painting method using 20 Kawasaki Robots. For
metallic coating, double coats are applied and aluminum flakes are provided to
shine the metallic paints.
After inspection and touch up, the PBOK, i.e. the paint body ok is sent to the assembly
In paint shop II, only ZEN and ALTO are painted. Paint used is Nerolac. There are 4
coatings of paint.
1] Phosphate coating
2] ED coating
3] IC coating
4] TOP coating
Inside portion of vehicle is painted manually and outside is by Robots.
36. MARUTI SUZUKI INDIA LIMITED
Before sending vehicle to painting process pretreatment is done to

The whole solution of ED acts as electrolytic solution. Vehicle before coming to ED dip,
it undergoes pre treatment. In that phosphating is done, in which Zn phosphate is made
to attach vehicle body which help in electro deposition, in this, vehicle acts as cathode
and paint as positive ions. When current is passed paint will be attracted by vehicle till
its thickness will be covered. ED is very accurate to apply. This is about whole process.
Rinsing is done after to remove excessive color. In rinsing industrial water is used which
will not be left go waste. That will be filtered and used again.
Ultra filtration is the process in which all the rinse pipes and dip tanks will be filtered and
cleaned, by this way water is recycled. Here Osmosis process is used to filter water.

In the assembly shop the body is loaded on an overhead conveyor. As the conveyor
moves the body, fitments are made at various stations. There are three Assembly
Shops named ASSY-1, ASSY-2 and ASSY-3. Plant 2 and Plant 3 have similar setup but
in Plant-1 there are separate assembly lines for separate models. The assembly shop
has a continuous production system. The assembly line can be subdivided into the
(a) Trim line
The vehicle proceeds through a series of Trim workstations where team members begin
by installing weather stripping, moldings and pads. Then they put in wiring, vents and
lights. After an instrument panel, windows, steering column and bumper supports are
added, it starts to look less like a shell and more like a car.
(b) Chassis Line
This is where many safety-related items are installed. Things like brake lines, torque,
gas tanks and power steering are double-checked. The engine is installed, along with
the starter and alternator. Then come suspension and exhaust systems. Then wheel is
mounted with the help of wheel nut fastening machine.
43. MARUTI SUZUKI INDIA LIMITED
(c) Final Line
From there the vehicle enters Final 1, which covers many interior items such as the
console, seats, carpet, glove box and steering wheel. This is also where bumpers, tires
and the battery are added, as well as finishing touches like covers and vents. Then,
Coolant, Brake oil, Power steering oil are filled and also the A/C gas are charged.
Different assembly shop layouts are followed to reduce material handling operations &
to facilitate material flow between workstations.
a) Straight-line layout – Car & omni line (Assy shop-1): Simplest layout in which
material enters at 1 end & leaves at the other end.
b) U shape layout – Assy shop 2 & 3: Receiving & shipping ends of line are at
same end of plant, due to material handling considerations (same forklift for both
needs) or external needs.
c) S shape layout – Esteem line (AS-1): Serpentine layout to fit longer assy line in
Separate door Assy line: - Doors are taken out from the vehicle at the first station of the
trim line. Doors fitted in the final line make working easier.

Auto closing to have clearance from Safety department & no extra material to be
procured from outside, only in-house material available inside the Maintenance
department to be used
49. MARUTI SUZUKI INDIA LIMITED
Initial study was done on site to check the safety risk, it was found that the pit can
not be reallocated to other area & it is required to carry on the repairs.
Manual cover is not used to closed the pit as it is very heavy & slips when somebody
walks on it.
Idea of providing a horizontal gate over pit with guided rails came, in this a gate was
fabricated as per opening’s size & rollers were provided on corners & rails were
provided to guide rollers to traverse smoothly.
The system worked well & with a push of hand the cover could be closed & opened.
But the problem of this system was nobody closed it after use & it is kept in open
50. MARUTI SUZUKI INDIA LIMITED
condition many times & in open condition the risk of falling inside pit was still
More study was done to provide automatic system on door so that it can open &
closed automatically as per requirements.
It was thought that a pneumatic cylinder should be provided to slide the gate over pit
which will be operated by providing sensing system .
51. MARUTI SUZUKI INDIA LIMITED
CASE NO-1 : 4 sensors were provided on top of pit where front tyres are positioned .
Sensors will sense the presence of vehicle on pit & will send signal to control panel to
open the air valve solenoid which will operate the gate by activating the air cylinder
towards open position.
After the gate opened the operator could do the repair work from beneath the vehicle.
52. MARUTI SUZUKI INDIA LIMITED
After the job is finished the car is driven off the pit. The issue of closing back the door
CASE NO-2 : When vehicle is driven off the pit the door remains open & risk of falling
inside pit remains there, in this case the de-activation of sensors S1 & S2 is linked to
auto closing of pit
The problem of automatically closing & opening the pit door was solved by activating &
de-activating the sensors S1 & S2.
53. MARUTI SUZUKI INDIA LIMITED
SAFETY CONCERN: In case someone is standing between the closing door &
does not notice the movement of closing the door he can be trapped in between the
door & pit wall & serious accident can happen.
New idea of closing the door in between in case some one or some object comes
between at the time of closing the door by pneumatic pressure.
CASE NO-3 : At the time of closing of door if someone or some object comes in
between the door 2 area sensors (S3) provided at both sides of pit which will sense the
presence of human or object & will stop the door suddenly & get it reversed to its home
(OPEN) position. With this system no one will be trapped between moving door & pit
55. MARUTI SUZUKI INDIA LIMITED
CASE NO-4 : At the time of closing the door if nothing is inside the pit & both area
sensors are clear of any obstruction the door will be closed safely & nobody will fall
inside the pit

Without the ability to locate and track units as they make their way through
manufacturing, testing and repair processes, managers lack the ability to achieve
optimum performance for their business and are forced to rely on outdated,
inaccurate data and labor-intensive processes.
The most powerful tool for any manager is accurate, real-time information about the
location and status of the work-in-process.
The Vehicle Tracking and Management System (VTMS), provides real-time
information to track, measure and manage vehicles anywhere within a facility, both
indoors and outdoors.
Vehicle Tracking and Management System is a ground-breaking step in automating
vehicle tracking and management in today's vehicle assembly, delivery chain and
fleet operations and is the first solution to provide real-time information to today’s
manufacturing management community.
Vehicle Tracking and Management System allows a vehicle manufacturer, delivery
chain or fleet operation to know in real-time or historically exactly where the vehicle
is located or has been.
Off-line processes are frequently a forgotten segment of lean manufacturing and
Vehicle Tracking and Management System is one of the world’s first systems to drive
efficiency and optimization in this area.
59. MARUTI SUZUKI INDIA LIMITED
In a Vehicle Tracking System solution, an RFID tracking tag is placed in each
vehicle typically before the vehicle enters the off-line processing areas., the solution
delivers real-time tracking information of the vehicle.
In addition, beyond the ability to locate a vehicle on demand, the tracking data can
be used to monitor such things as adherence to process, process cycle time, and
dwell time analysis for off-line areas.
Vehicle Tracking and Management System provides for accurate planning, execution
and monitoring of performance — making it the ultimate support tool for improving
processes and creating efficiency in off-line manufacturing areas.

VTS IN ASSEMBLY SHOP
Equipment activation – All equipment are connected through LAN with
VTS & as soon as triggering mechanism will get signal of presence of a particular
model it will pass on the signal to PLC of the equipment & the equipment will come in
that mode automatically. Vehicle Tracking from 1st control point to last control point
(WB ON to FC OK)
WIP (Work – IN – Process) between two control point
(For example if we want to see No. of vehicles in WIP in Paint Shop then we have to
give command to system for PB ON to PB OK & No of vehicles will be under Paint Shop
Shop Sequencing – In multi model mix production overprized lines what
sequence of models is in line will be known in advance & that sequence can be
printed by line printers which can be displayed for operator to see what model of
vehicle is approaching in next few hours to him.
In the Assembly Shop, VTS tracks vehicle at two points
Starts at AB-ON or assembly body ON and
Ends at AB-OK or assembly body OK.
At the AB-ON point, the data is transferred to the PLC and the vehicle sequence is
broadcast at various control points to different areas.
68. MARUTI SUZUKI INDIA LIMITED
Let us take a closer look on some of the areas points at which such broadcasts take
The Main Fundoshi Printer — this contains the details of components, and this
information helps the operators to fix the right components in the correct vehicles.
The Door Mini Fundoshi Printers — these printouts are stuck to the doors. Based
on this information, the doors are assembled.
The Process Check Sheet — this document is used to check the completion of the
processes at various checkpoints along the assembly line.
Engine Storage Out — engines are put on the Engine Docking Line according to
the AB-ON sequence, which is broadcast to the printer at the time of AB-ON. At the
Engine-Body marriage point, the Engine Number is matched against the Chassis
Number by scanning the barcode sticker.
Various other sequence printers are used for different sub-assembly lines:
Instrument panel sub-assembly;
Door latch sub-assembly; and
At certain points, PC Monitor applications are also used to broadcast the sequence.
The marriage of the engine with the vehicle is done at the EG Storage-Out point — this
is integrated with the VTS to avoid the possibility of wrong engine marriage.
The process ends with the AB-OK sequence.

To control the production and
quality in the highly
automated Engine assembly
line, Radio Frequency
Identification (or RFID)
technology is used.
To communicate with the
RFID tag and to pass on the production plan information, a Production Management
system (PMS) is required.
The system acts as an interface between the host computer and the production floor
and is used to transfer production plan information, dressing data to plant devices
and tags and obtaining production process data, traceability data and quality data from
76. MARUTI SUZUKI INDIA LIMITED
The system then stores the data to the host computer for storing analyzing and for
future useThe data related to testing is handled by the test management system or
TMS which in turn interacts with the PMS.
At these stations the magnetic RFID Tag communicates with the tracking system
known as PMS system via the Tag Controller to exchange and verify the data.
Additionally, the RFID tags also exchange data with other equipment and machines
on the assembly line in the same way, using the Tag Controller. The Tag contains
the data related to the engine kept on the palate.
The RFID Tag will start receiving data from set up station — for example, type of
engine, engine number, master data, etc. As the pallet goes along the line and
different operations are performed on the engine by various machines, the RFID Tag
continues collecting data from machines recording the operation done, its status, etc.
When the pallet reaches the release station, the entire data in the RFID Tag is
transferred to the PMS and after updating, it is flushed from the Tag. Now the tag is
ready for the next engine loading.

VTS IN VEHICLE INSPECTION(VI)
In the Vehicle Inspection Shop, tracking is done at two points:
After FC-OK, an FC-OK confirmation Sticker is attached to rear window of the
vehicle, and then the vehicles are transferred to the dispatch area.
In the vehicle inspection shop, the VTS is integrated with the TECH-1 system which
carries out the emission check and the air bag check.
Without the TECH-1 check FC-OK of the vehicle cannot be done.
This ensures that the vehicle has been passed through all the necessary checks.
78. MARUTI SUZUKI INDIA LIMITED
On the Quality Front, the VTS interacts with the quality gate system to provide faults
tolerance. All defects details are tracked through the VTS to ensure that no vehicle gets
FC-OK clearance without rectifying the defects.
Hence, VTS is a system that offers real time data to facilitate quick decision. It carries
out real time monitoring to detect errors and quality issues well in time; it broadcasts
messages that facilitate in-line correct evection at the shop floor.
