Introduction to Videocon
Videocon is an industrial conglomerate with
interests all over the world.
The company was incorporated as a public
limited company in August 1989 and was
originally promoted by Maharaja
International Ltd. to produce washing
machine, refrigerator, and dishwasher.
In India the group sells consumer products like Colour
Televisions, Washing Machines, Air Conditioners,
Refrigerators, Microwave ovens and many other home
applications. Videocon Group brands include
Sansui,Toshiba,Electrolux ,Ken star
Godreg ,Samsung,Whirlpool,LG etc.
Videocon is one of the largest CPT Glass
manufacturers in the world, operating in Mexico, Italy,
Poland and China.
Shops in Plant
Press shop
Paint shop
Vacuum forming shop
Pre-Assembly shop
Final Assembly shop
Press shop:-
forming press, commonly shortened to press, is
a machine tool that changes the
shape of a work piece by the application of
pressure.
Paint shop:-
To paint the side, back and door
panel.
Vacuum forming shop:-
In this section, the main cabinet and
door liners are formed.
Pre-Assembly shop:-
pre assembly means to mount components
onto a plate means they are ready to install
on the machine.
Final Assembly:-
In this we assemble all parts of refrigerator
after the verification of each and every part.

INVERTER:-
Inverter is a frequency drive used to invert
the A.C. to D.C.
The drive converts the phase from single
phase to three phase if the power supplied is
in single phase
Compressor
The compressor is the heart of the refrigeration
system
compressor it is then compressed depending on what
type of compressor it is from a cold low presure
refrigerant into a high presure hot refrigerant.
The compressor not only keeps the refrigerant
moving throughout the hole system it also creates a
pressure change.
Condenser
It is a heat-exchange device in a refrigeration system
It is a Device for reducing a gas or vapour to a liquid
Heat Exchanger A heat exchanger is a piece of equipment built for efficient heat
transfer from one medium to another.
They are widely used in space heating, refrigeration, air
conditioning, power plants, chemical plants,petrochemical
plants, petroleum refineries, natural gas processing, and sewage
treatment
FREEZER BOXThese are made from Aluminium Roll bonded,
which undergoes the following operation: - Notching & Punching Hammering. Butt-welding of inlet & outlet tubes
to the freezer box, further the hole Is cleared by drilling
How Does a Refrigerator Work?1.The compressor constricts the refrigerant vapor, raising
its pressure, and pushes it into the coils on the outside of
the refrigerator.
2. When the hot gas in the coils meets the cooler air
temperature of the kitchen, it becomes a liquid.
3. Now in liquid form at high pressure, the refrigerant
cools down as it flows into the coils inside the freezer and
the fridge.
4. The refrigerant absorbs the heat inside the fridge,
cooling down the air.
5. Last, the refrigerant evaporates to a gas, then flows back
to the compressor, where the cycle starts all over.
MAIN ASSEMBLY
To assemble the requisite accessories and to produce the final product.
Front side Assembly (Right) Wooden plate fitting.Lock fitting.Door bracket fitting.Freezer fitting.Door handle fitting.Door sealing.
Back side assembly
Compressor fitting.
Compressor connection.

Final testing.
Conclusion helped me to understand the practical
applications of manufacturing of refrigerator
and helped me to study on various machines
involved in manufacturing.
