In automobile manufacturing industry, there are complex operations that need to undergo before a car is completely produce. As part of the automotive employment, auto mechanics and engineers work together as a team to produce the desired mode car that they have designed ahead of time.

These are the operations to perform in order to put all the parts of the car together for a final assembly: Foundry foundations - workers pour molten into a mold where it cools and hardens into a casting. Castings are made for such parts as the engine block, cylinder head, or camshaft. Before the metal is poured, pattern-makers make patterns in wood or metal in the exact shape desired for the final casting. In preparing the molds, coremakers shape cores or bodies of sand that are placed in the molds to form the hollow spaces needed. When the casting cools, it is removed from the mold and trimmed to remove excess metal.

Auto mechanic jobs include machining operations which shape the castings with tools that cut away unwanted metal. This work is done by machine tool operators, who comprise one of the largest metalworking groups in the industry. As part of the auto job operation, tools and die makers also work in machining operations which are used by highly skilled workers. Tool makers make the jigs, fixtures, and other accessories that hold the work being machined in place. Die makers construct the dies used in stamping, pressing, forging, and other kinds of metal-forming operations. In the forge shop, automobile parts such as crankshafts and connecting rods are shaped with forge hammers and presses. Heaters heat the metal stock to be forged in a furnace and then pass it to hammer operators who pound the metal stock to be forged in a furnace and then pass it to hammer operators who pound the metal into various shapes between closed dies with drop hammers. Other workers who are involved in the automotive job in a forge shop clean, finish, and inspect forgings.



In the stamping process, the part is formed by being pressed between two matching forms under great pressure. As mounted in the press, the lower form is the die, the upper form is the punch. The sheet metal to be formed is placed between the punch and the die. In auto body jobs, there are three basic stamping operations. They are blanking, piercing, and forming. Blanking and piercing are often done at the same time. Blanking cuts the excess metal off the flat stock, leaving the piece from which the part will be formed. Piercing punches holes as needed.

Included in the functions of automotive technician jobs is a rigid monitoring of the parts, like forming- by which part is given its final shape. This sometimes requires a series of operations that may be performed progressively by a row of presses, each one bringing the part one step closer to its finished form.

The engine block must be constructed be fore it reaches the final assembly line. This is a process that involves numerous steps. When the engine block arrives in a manufacturing plant it is a metal case containing a series of holes or cylinder bores. Hundreds of separate operations must be performed by various machinist to turn it into the final product. One machine alone can do more than a hundreds of operations in a few seconds. In some plants, there are machines that work on seventeen engine blocks at the same time, finishing them to perfection.

In auto tech jobs, the machines that cut and drill the engine castings are aligned so that progressive operations may be performed as the engines move automatically from one group of machines to the next. In a typical plant, as the engine block is carried down an assembly line by overhead mechanical arms, workers install pistons, connecting rods, the crankshaft, the camshaft, fly wheel, oil pump, and all other major parts. Once the metal parts and engine block have been manufactured, the car is ready to be fully assembled. The first step in assembling a car is building the body. The various parts of the car body, such as the floor, roof, and side panels are put together on the longest feeder line in the assembly plant. Special framing fixtures hold the parts in place while they are welded or bolted together. Welders use electric welding machines to join parts together. Welded joints are much stronger than joints fastened together by bolts and nuts, but parts attached by nuts and bolts are easier to remove for repair or replacement.

Technicians and engineers, who deal with these automobile jobs always in double diligence to produce a precise output of automobiles. The car doors and deck lid are then added. All metal surfaces are ground smooth and the body thoroughly cleaned. The body is now moved to the paint department. After certain joints are sealed, protective layers of primer coating are applied. The body is then sanded and washed to provide a good surface for the finish color. At the color spray booth, multiple coats are applied. Next, the body moves to an oven where the paint is baked to a hard, bright luster. Then trimming and sewing operations begin to provide the motor vehicle with interior parts. Eventually, these auto body jobs with a sophisticated and complex nature of operation, produce a rewarding result when a quality car is displayed with pride.
