Default Re: How cars are made from Materials

Even before the cars are put on design board, this is how they look as pure RAW material:
These will become your POLO, JETTA or PASSATS.

Let me add a bit. There have been major developments in steel. As stated by Aditya Mittal some time back, over 70% of the steel they supply to the automotive industry did not exist five years ago.

Just a bit curious here, in what way does the paint job of a local workshop differ from that done by the A.S.S.

The local workshop guys too guarantee a perfect match based on 'computer shade matching'. So if the shade does not match for touch up jobs, is there a difference in quality of paint material used or is one or more of the above ingredient list missing? I intend to understand the difference between paints used by local workshops and A.S.S.

R&D and Paint booth are two areas that are very heavily guarded in most automobile factories.

Paint booths are closed to keep out dust and other contaminants that can settle on the cars body during painting process which results in defects. Another reason is to avoid the risk of a fire, due to many flammable chemicals around. hence everyone entering a paint booth area has to be fully covered in anti static body suit, which is a special material woven with special strands to prevent static. A sudden spark could be catastrophic.

Some manufacturers even use special anti static shoes in paint booth areas.

In most manufacturing plants, visitors are kept out of paint booths, they otherwise can visit other parts like the press, weld, assembly areas with prior approvals and safety measures !

Any doubts, members please post, as i have worked in an automobile manufacturing facility, i will answer to the best of my ability

Default Understanding Car door seals

The door seal plays an important role in a car. It is a gasket made of rubber material to seal off the interior from external noise and wind. There are 2 parts in a seal. Primary seal and Secondary seal.
Can anyone please tell me the difference between the two? What are their functions? How are they connected? Tried searching online. Not much help. Couldnt find any details nor a proper picture explaining it.

Mods, COuldnt find this info on any other thread. Please delete if found inappropriate.
