it is a ppt on how cars are manufactured right from start to end great process must watch!

3. • OUR PROJECT IS ON MANUFACTURING
PROCESS OF AUTOMOBILES.
• HISTORY OF AUTOMOBILE STARTED WITH
THE FIRST STEAM, ELECTRICAL,WIND-MILL,
POWERED AND GASOLINE CARS.
• HERE WE ARE GOING TO DESCRIBE ABOUT
VAROUS PROCESS BEING CARRIED OUT
WHILE PRODUCTION OF AUTOMOBILE.

4.  THE CHASSIS
PRODUCTION UNIT.
 THE E-COATING
 THE SURFACE FINISH
CENTER.
 THE PRE-ASSEMBLY.
 THE FINAL ASSEMBLY
LINE.

5. BUILDING A FRAME OR BODY IS MOST
CHALLENGING WORK.
AN AUTOMOBILE’S BODY IS MADE UP
OF ALUMINIUM RATHER THAN STEEL
WHICH MAKES THE BODY STIFFER
AND SAVES THE CARS WEIGHT.
THERE ARE AROUND 2000 WELDS IN
CHASSIS PRODUCTION WHICH ONLY
WELL SKILLED WORKERS CAN
PERFORM IT.

8. • AFTER CHASIS PRODUCTION..
• THE CAR’S BODY IS MOVED TO ANOTHER UNIT WHERE IT IS
PROTECTED BY CORROSION.
• THE BODY IS SUBMERGED IN CHEMICAL WHERE IT IS
ROATED IN 360 DEGREES TO GET COATED FROM INSIDE AND
OUTSIDE.
• THE COATING IS OF:
 NICKEL
 MANGANESE
 ZINC
• THEN THE CAR IS EMERGED IN AN ELECTRICAL CHARGE
SOLUTION WHERE THESE COATING STICKS TO THE BODY
LIKE APERMANENT MAGNET AND PREVENTS IT FROM
RUSTING.

10. HERE THE WORKERS BUILD THE MAJOR
COMPONENTS OF CAR LIKE:
 DOORS.
 INSTRUMENT PANNEL.
 THE ENGINE.
THE WORKERS POLISHES THE BODY AND MAKES A
PERFECT FINISH.
THEN AN INSPECTOR INSPECTS IT AND EVEN THE
SLIGHTEST AND MINOR MISTAKES DOES’NT
MOVES THE CAR TO ANOTHER UNIT.

13. THE FINAL
ASSEMBLY LINE
IS LATER
DIVIDED IN 7
UNITS:

14. HERE ASSOCIATES
INSTALLS BLOCKS
OF HIGH DENSITY
FOAM AND THIN
SOUND PROOFING
SHEET LIKE
MATERIAL TO
PREVENT LOW AND
HIGH FREQUENCY
NOISE.

15. IN THIS SECTION,WIRING IS DONE ALL
OVER THE BODY WHICH POWERS AND
CONTROLS CARS ALL ELECTRONIC
COMPONENTS

16. HERE THE
TECNICIANS
INSTALLS STRONG
AND STIFF
INSTRUMENT
PANEL
MADE OF CAST
MAGNESIUM
WEIGHING UPTO 15
POUNDS.

22. 1. Production becomes very fast.
2. The product obtained is relatively perfect.
3. Chances of faults and mistakes are negligible.
4. Human or manual efforts are reduced to greater extent.
5. The production takes place very systematically and in a proper sequential
order as it is desired.
6. Accidents occurring due to operations like cutting, drilling, grinding, etc are
very rare.
7. Objects like glass and such other heavy and fragile parts can be handled by
robots.
8. The automobile firms gain profit as they have to spend more money on
human workers so they prefer to have robotic and computerized production.
9. Automobile firm owners have a big benefit of these that they don’t go on
strikes.
10. The product gained by the automated, computerized and robotically
manufacturing is comparatively very advanced.

23. 1. Due to the installation of robotic and computer operated
machining there has been a substantial decrease in the
employment of skilled workers.
2. There are problems like lower build qualities.
3. Higher initial capital investment.
4. Assembly lines typically cannot modified easily or cheaply to
create different products, resulting in inflexibility.
5. Sometimes an assembly line can also allow a robot to do the
work of many, which may lead to a loss of overall production.

25. The automotive manufacturing processes play a major role in deciding
on the vehicles’ design characteristics and the overall cost. Thus it is
very important for designers and engineers to understand the current
manufacturing infrastructure available in their company’s production
lines. This will pinpoint the manufacturing capabilities and limitations.
At the end of the day, the designer will specify the design tolerances but
the machine will control the achieved tolerances.
Also, we finally come to the conclusion that automated manufacturing
and assembly of automobiles have relatively much more influence in
terms of quality as well as performance.
