Abstract
As we mentioned earlier that our main purpose for this internship/ industrial training was to gain
knowledge and get perspective regarding the operation of a mega production facility. Our wishes were
more than answered when HONDA CARS INDIA Ltd. provided us with an opportunity like this to
intern at the Tapukara plant. This internship has been really an eye opener for us all. We were placed
in the Utility dept. and primarily toured all the sub divisions coming under them. Utility dept. was
responsible for mainly running and aiding the plant behind the scenes. It provided and helped in
maintenance of the 4 major industrial utilities i.e. electricity, water, natural gas & air. Utility dept.
does not manufacture any vehicle but without their aid & behind the scenes hard work even
manufacturing dept. can do nothing. We also had the great opportunity to observe different
departments other than the Utility. It was the first time that we had seen a mega factory up close &
personal. One thing which struck us was that how such a giant manufacturing plant operates, it is so
huge that it has several departments some of which functions individually as a small autonomous unit
itself. Each dept. can have many sections as well, in order to manage them there are section heads and
above them there is a consolidated head called the Head of Dept. (H.O.D) . A plant this big is like an
enlarged machine which has individual intelligent parts which function individually and together to
create a final product i.e. a Honda Cars .

HONDA Cars India Ltd.- Brief Profile
Honda Cars India Ltd (HCIL) is a subsidiary of the Honda of Japan for the production, marketing and
export of passenger cars in India. Formerly known as Honda Siel Cars India Ltd, it began operations
in December 1995 as a joint venture between Honda Motor Company and Usha International of
Siddharth Shriram Group. In August, 2012, Honda bought out Usha International's entire 3.16 percent
stake for 1.8 billion in the joint venture. The company officially changed its name to Honda Cars
₹
India Ltd (HCIL) and became a 100% subsidiary of Honda.
HCIL's first manufacturing unit was set up at Greater Noida, U.P in 1997. The plant is spread across
150 acres and has an annual production capacity of 120,000 units. HCIL's second plant in Tapukara is
the first car manufacturing plant in the state of Rajasthan. The state-of the art Power train and Press
shop in Tapukara plant have been operational since September 2008. This facility is spread over 450
acres and has an annual production capacity of 120,000 units. HCIL started the production of cars
from its Tapukara Plant from February 2014.
Utility Department
Utility dept. as we mentioned earlier is the dept. responsible for maintaining & supplying water,
electricity, natural gas & air to the plant where they are utilized in production. The 4 major utilities in
industry are electricity, water, natural gas & air. Without the utilities a plant cannot produce because
it's the key component on which all the machines and tools operate which are then used to convert raw
material into finished goods. The utility dept. has different kinds of treatment plants, substations,
switch house, compressor houses, diesel generator house etc. Basically it deals with energy and its
different forms. It's like the fuel that is required to run a machine, in this case utility dept. is the fuel &
the whole plant is the machine.

Compressor House
Definition: By definition a compressor house is that area of the plant that supplies clean and dry
compressed air to different departments in the plant for further use. There are namely two compressor
houses in the Honda plant, they are compressor house-1 & compressor house-2.
Importance & Uses of Compressed Air: Compressed air, commonly called Industry's Fourth Utility, is
air that is condensed and contained at a pressure that is greater than the atmosphere. The process takes
a given mass of air, which occupies a given volume of space, and reduces it into a smaller space. In
that space, greater air mass produces greater pressure.
Industrial Plant Maintenance: Air tools, such as paving breakers, are used to fix cement floors, to open
up brick walls for assorted service lines, and other comparable work.
For other maintenance work, plants can use air-operated drills, screwdrivers, and wrenches, provided
that the air outlets are well placed throughout the plant. Painting can be done using paint-spraying
systems.
On the Production Line: Pneumatic tools are convenient for industrial production because they have a
low weight-to-power ratio, and they may be used for long periods of time without overheating and
with low maintenance costs. Chipping and scaling hammers are used in railroads, oil refineries,
chemical refineries, shipyards, and many other industries for general application. They are also used
in the foundry for cleaning large castings, and to remove weld scale, rust, and paint in other industries.
Pneumatic drills can be used for all classes of reaming, tapping, and drilling anytime that the work
cannot easily be carried to the drill press and for all classes of breast drill work. These air-powered
drills are also often used for operating special boring bars, and in emergencies, for independent drive
of a machine tool where required horsepower is within their capacity.

Diesel Generator House
Definition: A Diesel generator house or D.G. House as it's called is that unit of the plant which houses
the diesel generators to provide electricity whenever the electric supply from the main power grid fails
or during a power cut.
D.G. House in the plant consists of 5 diesel generators. A diesel generator is the combination of
a diesel engine with an electric generator (often an alternator) to generate electrical energy. A diesel
compression-ignition engine often is designed to run on fuel oil, but some types are adapted for other
liquid fuels or natural gas. The packaged combination of a diesel engine, a generator and various
ancillary devices (such as base, canopy, sound attenuation, control systems, circuit breakers, jacket
water heaters and starting system) is referred to as a "generating set" or a "genset" for short. Together
these gensets can provide around 11 kV electric supply almost equivalent to grid but they are very
expensive to run due to high consumption of fuel used.
Generators Present: Out of the 5 gensets, 4 are from Cummins and 1 is from MAN. Out of the 4
gensets from Cummins, 2 can generate 1.2 MW & other 2 can generate 1.6 MW. They have speeds
ranging around 1500 rpm. Cummins generators are utilizing a V-16 diesel engine which is liquid
cooled as well as turbocharged. It also has 2 Fleetguard air filters for filtering purposes. It also has 4
fuel filters out of which 2 are ultra fine filters.

A Cummins diesel generator (source: www.gongyi-generator.com)
The last genset present is the genset from MAN. It's large genset that is capable of producing 2.5
MW. It's a pneumatic or air starter generator. Compared to a gasoline ("petrol") engine, diesel
engines have very high compression ratios to improve engine efficiency. An electric starter powerful
enough to turn a large diesel engine would itself be so large as to be impractical, thus the need for an
alternative system. When starting the engine, compressed air is admitted to whichever cylinder has
a piston just over top dead centre, forcing it downward. As the engine starts to turn, the air-start valve
on the next cylinder in line opens to continue the rotation. As this goes on, fuel is injected into the
Page 9

cylinders, the engine is then under way and the air is cut off. This genset can run on diesel as well as
on furnace oil. It's a low speed engines with speed ranging around 750 rpm.

132 KV Switch House & Substations
Introduction: The present-day electrical power system is A.C. i.e. electric power is generated,
transmitted and distributed in the form of alternating current. The electric power is produced at the
power stations which are located at favourable places, generally quite away from the consumers. It is
delivered to the consumers through a large network of transmission and distribution. At many places
in the line of the power system, it may be desirable and necessary to change some characteristic (e.g.
voltage, A.C. to D.C., frequency, Power factor etc.) of electric supply. This is accomplished by
suitable apparatus called sub-station. For example, generation voltage (11KV or 6.6KV) at the power
station is stepped up to high voltage (say 220KV or 132KV) for transmission of electric power. The
assembly of apparatus (e.g. transformer etc.) used for this purpose is the sub-station. Similarly, near
the consumer’s localities, the voltage may have to be stepped down to utilization level. This job is
again accomplished by a suitable apparatus called substation.

(source: www.blackburn-starling.co.uk)
Types of Substations in Plant:
Transformer sub-stations, sub-stations which change the voltage level of electric supply are called
transformer sub-stations. These sub-stations receive power at some voltage and deliver it at some
other voltage. Obviously, transformer will be the main component in such sub-stations. Most of the
sub-stations in the power system are of this type.
Switching sub-stations, sub-stations that do not change the voltage level i.e. incoming and outgoing
lines have the same voltage. However, they simply perform the switching operations of power lines.
Different Components of Substation
a) Lightening Arrestors: Lightening arrestors are the instruments that are used in the incoming feeders
so that to prevent the high voltage entering the main station. This high voltage is very dangerous to
the instruments used in the substation. Even the instruments are very costly, so to prevent any damage
lightening arrestors are used. The lightening arrestors do not let the lightening to fall on the station. If
some lightening occurs the arrestors pull the lightening and ground it to the earth. In any substation
the main important is of protection which is firstly done by these lightening arrestors.
The lightening arrestors are grounded to the earth so that it can pull the lightening to the ground.

b) Earthing : The earthing practice is adopted at generating stations, sub-stations and lines should be
in such a manner as to provide:
1)Safety to personnel
2)Minimum damage to equipment as a result of flow of heavy fault currents
3)Improve reliability of power supply
c) Capacitor Voltage Transformer (CVT): A capacitor voltage transformer (CVT) is a transformer
used in power systems to step-down extra high voltage signals and provide low voltage signals either
for measurement or to operate a protective relay.

d) Isolators with Earth Switches (ES):Isolators are the no load switches and used to isolate the
equipment. (Either line equipment, power transformer equipment or power transformer). With the
isolators, we are able to see the isolation of the equipment with our naked eye. The line isolators are
used to isolate the high voltage from flow through the line into the bus. This isolator prevents the
instruments to get damaged. It also allows the only needed voltage and rest is earthed by itself.

e) Current Transformer(C.T.): Current transformer is a current measuring device used to measure the
currents in high voltage lines directly by stepping down the currents to measurable values by means of
electromagnetic circuit.

A Current Transformer (www.muradnagar.infoisinfo.co.in)
f) Potential Transformer(P.T.): Potential transformer or voltage transformer gets used in electrical
power system for stepping down the system voltage to a safe value which can be fed to low ratings
meters and relays. Commercially available relays and meters used for protection and metering, are
designed for low voltage.
A Potential Transformer (www.tucsontransformer.com)
g) Circuit Breaker: The circuit breakers are used to break the circuit if any fault occurs in any of the
instrument. These circuit breaker breaks for a fault which can damage other instrument in the station.
For any unwanted fault over the station we need to break the line current.
Page

14. HONDA CARS INDIA LIMITED
This is only done automatically by the circuit breaker. These are load switches. It is able to make or
break the normal load current as well as the fault currents.

Types of Circuit Breakers used in Plant
1)Natural air (called air circuit breakers-ACB) (415v)
2)Vacuum (called vacuum circuit breaker-VCB)
3)SF6 gas (called Sulphur Hexafluoride-SF6 gas CB)

A Circuit Breaker (www.cccme.org.cn)
h) Bus: The bus is a line in which the incoming feeders come into and get into the instruments for
further step up or step down. The first bus is used for putting the incoming feeders in la single line.
There may be double line in the bus so that if any fault occurs in the one the other can still have the
current and the supply will not stop.

Project Undertaken: MSDS Label Making & Evaluation
During our second week of training we issued a project by Anshul Aggarwal san regarding MSDS
labels & evaluation of chemicals used in Utility department.
Definition: A Material Safety Data Sheet (MSDS) is a document that contains information on the
potential hazards (health, fire, reactivity and environmental) and how to work safely with the
chemical product. It is an essential starting point for the development of a complete health and safety
program. It also contains information on the use, storage, handling and emergency procedures all
related to the hazards of the material.
Problem: MSDS is hard to read. Traditionally the intended readers of MSDSs were occupational
hygienists and safety professionals. Now the audience also includes employers, workers, supervisors,
nurses, doctors, emergency responders and workers.
Solution: To ensure that MSDS users can quickly find the information that they need, the information
should be in an easy-to-read format and written in a clear, precise and understandable manner.
Therefore, we designed an easy to understand MSDS label using NFPA(National Fire Protection
Agency) standard diamond, used graphic images in PPE(personal protective equipment) & created an
information column so that even a layman can understand. We also labelled the diamond with
alphabets to prevent identification problems in case of a black & white printout.
We were also given a list of chemicals in the form of an Excel sheet. These chemicals are used in
Utility department. Our task was to correctly evaluate the chart. We corrected any wrong information
and added any missing information regarding the chemicals.

Assembly Frame Shop
Definition: An assembly line is manufacturing process in which parts are added as semi-finished
assembly moves from work station where parts are added in sequence unit assembly is produced.
The main assembly line consists of exterior, wiring, interior and chassis which at various points are
connected to sub-assemblies including door, tires, instrument panel engine and rear axle. The efficient
layout with synchronized sub-assembly conveyors are made for more efficient control over human,
machine interaction and logistics.
Vehicle bodies are here to run on FDS(Friction drive system) conveyor of overhead type making it
easier for operator to work on sub-assemblies. The integrated nature of assembly line also results in
lower physical fatigue for operators, thereby inc. their efficiency.

PO (Injection Moulding Shop)
Definition: PO shop is an alias for injection moulding shop. Injection moulding is
a manufacturing process for producing parts by injecting material into a mould. Injection moulding
can be performed with a host of materials, including metals, glasses,
thermoplastic and thermosetting polymers. Material for the part is fed into a heated barrel, mixed, and
forced into a mould cavity, where it cools and hardens to the configuration of the cavity.  Injection
moulding is widely used for manufacturing a variety of parts, from the smallest components to
entire body panels of cars.
Working: The injection unit takes plastic raw material granules, heats them until molten, and injects
them into the mould.  Machines have a barrel that contains a screw, the barrel has heater bands around
the outside which raises the temperature(200~280℃), to the correct level to melt the plastic. The
rotating screw(50-150 rpm) forces the plastic along the barrel (at about 3500 tonnes pressure).  This in
turn forces the screw back as the molten material collects at the end of the screw.  When the right
amount of material for the next shot has accumulated the screw stops rotating.  The screw then acts
like a plunger moving forward and forcing the molten plastic into the mould tool. The clamping end
with moving platen takes half of the mould tool.  This opens and closes the mould and supplies
sufficient force to keep the mould closed when molten plastic is injected under pressure.

POPA (Bumper Painting) Shop
Definition: POPA dept. is nothing but an alias for bumper painting shop. Freshly produced bumpers
are transferred from plastic injection to the bumper painting shop, there bumpers of different models
are painted according to the requirement of assembly frame department.
Operation: As we mentioned earlier freshly produced bumpers come from plastic injection shop, these
bumpers have information tags on them regarding model number, colour, finish etc. information on
them.
The bumpers are not metallic in nature and constructed from plastic granules. Therefore, the first coat
on the bumper is the primer coat or the undercoat. Priming ensures better adhesion of paint to the
surface, increases paint durability, and provides additional protection for the material being painted.
The second coat is the base The base coat is applied after the primer coat. This coat contains the
visual properties of colour and effects, and is usually the one referred to as the paint. Usually sprayed
on top of a coloured basecoat, clear coat is a glossy and transparent coating that forms the final
interface with the environment. For this reason, clear coat must be durable enough to resist abrasion
and chemically stable enough to withstand UV light. When the painting process is completed the
bumper goes through a polishing zone and it's also cured under the ultra violet lights also called the
Page

zebra checking point. The completely finished bumpers are then sent to operators for attaching the
font grills and headlights( tail lights in case of rear bumper ). The finished part i.e. the front end or
rear end is then sent to the assembly frame shop.

Spin Casting
Definition: Casting is a manufacturing process by which a liquid material is usually poured into a
mould, which contains a hollow cavity of the desired shape, and then allowed to solidify. The
solidified part is also known as a casting, which is ejected or broken out of the mould to complete the
process.
Spin casting: Spin casting is a special casting technique which uses centrifugal force to produce
hollow casting. Due to the centrifugal force involved no core is required in this process which makes
it very convenient and advantageous.
Process: Metal (or alloy) to be casted is melted in a furnace by heating it to the required temperature
(1200-1500°C) and this molten metal is the passed to the holding furnace. A permanent mould is
rotated continuously about its axis at high speeds (1000-1500 rpm) as the molten metal is poured. The
molten metal is centrifugally thrown towards the inside mould wall, where it solidifies after cooling.
The casting is usually a fine-grained casting with a very fine-grained outer diameter, owing to chilling
against the mould surface. After the process is complete, we obtain 1 long tube which is passed
through shot blast in which the surface impurities are removed by small steel shots bombarded on the
surface of the tube. This tube is then passed through a CNC cutting machine which is programmed for
cutting is into the desired no. Of cylinder liners (14 in case of petrol and 12 in case of diesel engine).

After the desired length is obtained these liners are finish machined which involves boring and
chamfering. The process is concluded with quality inspection which involves inspection for any
deformity, defects and dimensional accuracy. The manufactured cylinder liners are then sent to engine
assembly for installation.

Press Shop
Definition: A forming press, commonly shortened to press, is a machine tool that changes the shape of
a work piece by the application of pressure. Presses can be classified on various parameters for
example, according to their mechanism: hydraulic, mechanical, pneumatic etc.
Operation: There are 2 types of press machines are being used in plant. One is mechanically operated
and other is servo motor operated. The output is measured in strokes per minute or SPM. the
mechanical press has 9 SPM & servo operated press has 11 SPM. The production of a vehicle begins
in the press shop, where sheet metal is integrated into the manufacturing process and the first shapes
of the later vehicle are created.

b)Servo Operated Press: As the name suggests, a servo operated press's ram is controlled and run by
servo motor which is nothing but an electric motor with reduction gears. It uses a feedback
mechanism in order to control precisely timed repetitive automatic tasks.
Conclusion
This internship was a great opportunity for us engineering students & we again would like to thank
HONDA for providing this to us. As we have mentioned earlier our main purpose coming here was to
gain experience, get a feel how a large manufacturing plant operates, what is the code of conduct etc.
It's safe to say that our expectations were blown away, coming here we realized how much hard work
and their precise management is required to run the plant round the clock. For a layman it must be
difficult to comprehend how this plant works but being here we realized it's possible because every
employee from each department does his/her designated task efficiently in shortest possible without
compromising on quality. We were placed in the Utility department, in simple terms we can say that
Utility department is the fuel if this plant is a machine & a HONDA vehicle is finished product.
Utility department doesn't aid in production of vehicles directly but supplies the other department that
are directly involved in production with the resources that are critically needed for the completion of
their task. Our time at HONDA was a great learning experience for us & we hope we can apply some
knowledge in our future workplaces.
