3. 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.

4. 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.

5. Shops in Plant Press shop Paint shop Vacuum forming shop Pre-Assembly shop Final Assembly shop

6.   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.

7. Paint shop:- To paint the side, back and door panel. Vacuum forming shop:- In this section, the main cabinet and door liners are formed .

8. 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.

10. Parts of fridge 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

11. 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.

12. 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

13. FREEZER BOX These 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

14. 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.

15. 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.

16. Back side assembly   Compressor fitting. Compressor connection. Condenser fitting. Leak testing. High voltage testing. Vacuum. Final testing.      

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