Automotive assembling started in
Pakistan in 1984 with Suzuki Japan started assembling of the cars as named Pak Suzuki.
Then after other car manufacturing companies stepped a head to start working in
Pakistan with collaboration of Local Companies such as IMC (Toyota, Daihatsu),
Atlas group as (HONDA Atlas) and some
industries invested itself. Nissan, Hino, Isuzu, Master, Daewoo. Today Pakistan’s
collaboration in vehicle manufacturing is 45% by volume.
The assembling of the vehicle/cars starts from the body shop. Sheets
are shaped in the required manner which is done by using several Mechanical and
hydraulic a presses. All the sheet metal Body parts get assembled by spot
welding in order to make a shell. The shell is then transferred to the paint shop
where the body get painted. Usually process done using is E.D (electro-deposition)
of powered paint on the shell. The E.D paint process comprises of following
steps:
2. Pretreatment(ED deposition)
3. ED oven
4. Sealing
5. Sealing oven
6. Dry sanding
7. Top coat(surface)
8. Top coat oven
9. Wet sanding
10. Top coat(final paint)
11. Top coat oven
After paint body is transferred to the trim line i.e. assembly line so that its main assembly can be executed. In order to reduce the complexity and to increase the production rate the assembly line is divided into different stages so, that the assembling can be done in a proper manner without having problems/Bottle neck. Every part of the vehicle is installed step by step on assembly line. Such as electrical wiring, dashboard, locks, Gates, etc.
This operation is occurred on one hand but on the other hand chassis drilling operation is simultaneously running on other side for the assembling of different brackets, fuel tanks, Pipes and radiator. During chassis assembly, special plates which is actually a jig that is clamped to the side drills, then with the help of drilling machine all the desired holes are drilled. Engine assembling is done in which all the pulleys, camshaft, pistons and other parts are assembled. In engine assembly some of the parts are first washed with water and then with chemical solution. These parts include flywheel, crankshaft and oil pan. Engine assembly is divided in different stages for the easiness of the worker.
After assembling of the vehicle
here comes the job of quality department. The basic job of quality inspector is
to check whether all the equipment are installed and working properly or not. Some
tests are done on the vehicle including brake test, head lamp test and several
other tests. Final inspection is done on the body before road test to check all
the components are installed properly. If any issue comes out then the vehicle
is again sent back to the line for rework.

assembly shop.
