Rear headlight | ||
One of the most important parts in a car is the rear headlight. A typical automotive headlight has a series of components that have one or more functions. Unlike the headlight, in the rear light the bezel, in addition to being the reflective part, also acts as a headlight lock. In practice, a package is applied to the lens and then the headlight is closed with a bevel. The rear bezel is usually made in PC / ABS or PBT, the seal to prevent the areas of the lens from fogging after a time is made in TPE and a lens in PMMA. The most notable part of the headlights is the lens. The lens is probably one of the most important components of the headlight because it has several important functions. |  | |
| Bezel | ||
The bezel is the component that concentrates the light and directs it in only one direction so that it has the maximum effect. The bezel is manufactured with different techno-polymers without load and usually in gray or black color according to the car manufacturer, among the most used are: PBT, PC / ABS and ASA The injected bezel is then metallized with sublimated aluminum, to create a mirror that can reflect all the light in the direction of travel of the vehicle. |  | |
| Sello | ||
Acumulación de condensación dentro del faro sucede debido a una serie de razones. Hay ventilaciones en la parte superior e inferior de la carcasa del faro que son necesarias para igualar la presión y evitar que la lámpara se agriete y falle. Las áreas de la lente pueden empañarse después de un tiempo. El proceso de nebulización no influye en la óptica. Para minimizar la acumulación de condensación dentro del faro, se pone un sello de elastomero SEBS , tal vece sobre-inyectado direttamente en la carcasa de polipropileno o arriba de la lente de policarbonato. |  | |

The requirements for a headlight lens are the following: Must have good optical property (transparent) It has to be strong (modulus of minimum elasticity and high resistance to fracture) 3-D shapes Good resistance to mild acids and petroleum derivatives. Good wear resistance to resist scratches (hardness) It should not be affected by UV rays The rear lenses are made in PMMA edifrentes colors: red, orange and white |  | |
