The Automotive Industry
Metal is one of the most widely used materials in a car, with major components such as body structure as well small parts like screws and brackets manufactured using steel, aluminium and even alloys. Metal components are commonly manufactured by stamping, forging, machining or casting.
Today’s cars now use tremendous amounts of plastics as they are durable, versatile and cost effective. Dashboard, gauges, door handles, floor mats, seat belts, airbags and many other parts are all made from different types of plastics.
Plastics are manufactured through a process called injection, where the plastic is heated and forced into a mould cavity. Some plastic parts are made by extrusion, a process where the plastic is melted and formed into a long, continuous shape. Tubings and plastics trims are manufactured through plastics extrusions.
Rubbers are not only used to manufacture tyres, parts such as wiper blades, engine mounts, seals, hoses and belts are also made from rubber. Like plastic, it’s a very durable, cost effective and flexible material that has several uses in cars.
The electrical system of a car is a closed circuit with an independent power source, the battery. Current flows from the battery through a complex network of color-coded wires to an electronic component, such as headlamps and sensors, and back to the battery through the car’s metal body.
Automotive electronic systems and engine computers do everything from regulating fuel to diagnosing problems. Modern day vehicles employ between 30 and 80 separate electronic controllers for safety systems, vehicle monitoring, communication and entertainment.
Trim & Interior
Trims and interior components provide comfort for passengers and add aesthetics values a car’s cabin. Most vehicle models are offered with several trim and interior packages to fit various preferences.
Typically, interior components are formed with a combination of plastic, fabric and leather parts. More luxurious models even offer crystal and wooden parts for an added premium feel inside the cabin.
