The rising design of different ranges of and their brands had given concern to how these are made, some claim their or brand is superior to another due to some factors such as; functionalities, long time records of their brand, how current their design model is, the rigidity of the physical parts of the , the cost of acquiring such , etc. but besides all these there are basic steps that all manufacturers do follow irrespective of the brand and model.
In the automobile plant, there are different mechanized meant for the purpose of assembling of the , and most of them (if not all) are automated. For production to be easier and faster most of the manufacturers can only produce 60% of the entire parts while the rest are supplied to them by their partnering bodies for parts production. It takes an automobile industry with long time existence history to have up to 90% of their produced by them and such are few in number.
We are going to discuss the few steps that production due undergo to ensure quality and of the .
As mentioned earlier, the plant is an enormous assembly point, each as a collection of small assembly lines designed to produce sub-assemblies of finished components such as body, , and suspensions, etc. which can be assembled into the later on.
The are put together in a carefully analyzed sequence called the assembly line, to ensure the is assembled and inspected in the most efficient manner.
The manufacturing process always has job forms accompanying them, giving the specification of the job batch and the process made so far.
The or human working sequences are;
First, the body shell is welded together, underbody inclusive.
and lids are bolted on and all rough edges and marks are removed from the panel ready for .
The underbody is dipped in a rust proof, epoxy resin and thereafter.
The whole body is dipped in a large tank containing primer .
The body is then stoved in an oven.
The body is then sprayed.
After the above steps, further stoving of the sprayed body is carried out in the shop and thereafter, the body travels on an overhead conveyor together with the , boot, lid, and bonnet and are then ready to be moved to the assembling line. As the body begins its journey on one line, the and other parts begin theirs in another line until the entire line final products meet in the final stage of assembling of the sub-assembled parts.
Finally, at the end of the assembling, the steering is set up and the lights are correctly adjusted. The is filled with water, petrol is put in the tank, and additional oil is put into the , the is given a brief test on a dynamometer or rolling road. The can be driven at various speeds using all the ratios in the . Its performance, steering, and braking are checked against a standard, and the is then driven off the line and given brief road test.
