The earliest vehicles invented did not have windshields; people simply wore goggles whilst driving to protect their eyes. Things quickly moved on as it became obvious that protection from the elements was necessary and the windshield was invented md802.

The earliest designs were far better than just a pair of goggles however they proved dangerous as were not shatter proof. Upon any sort of impact they would break and in a number of accidents people were hurt by the sharp shards of glass.

Glass lamination was the next step and is how most windscreens are made today. This involves sandwiching a layer of vinyl in between two layers of glass; this makes the screen shatterproof.

To make a windshield the process begins with a flat sheet of glass. A plotter controls a cutting wheel which moves over the glass which scores the correct shape for the screen. Next a robotic arm which holds a torch moves over the score along the same line; this cuts the glass, giving it a clean finish. Next the glass is sanded down by machines removing the sharp edges from the screen. This process is called seaming.

The next part of the process involves the glass passing through water and soap sprays on a conveyor belt in order to clean it after the sanding. Talcum powder and water are then sprayed onto the sheet to avoid the first bit of glass sticking to the second sheet. The two sheets are laid on top of one another temporarily for storage.

Next a black paint border is silk screened onto the glass and this will be the inner part of the windshield. The glass is then transferred to a bending iron which is shaped in the specific design of the particular windshield; this will be different for different manufacturers launch x431 v+. The glass and bending iron are then moved into a bending oven which heats the glass to 750 degrees Celsius causing it to melt into the correct shape. The glass then goes through a cooling process to toughen it in its new form.

The inner vinyl layer is then cut into the correct shape and sandwiched between the two layers of glass by machinery. This is the general process of how a windshield is constructed in a factory environment. The idea behind lamination is that if an accident occurs, instead of shattering the glass will fracture but the inner vinyl layer helps to hold the broken bits of glass together.
