OBJECTIVE

Along of these last years, welding laser technology is being improve and growing in a very competitive market, where is possible finding innumerous solutions, since glue to complex processes as ultrasonic welding process.  This market increment is achieved by the versatility that is type technology is capable, mainly because the linkage between the laser head and the robot. With this its possible weld almost whole plastic parts, that exist on the market, the exception is welding different materials with a melting temperature difference of 50ºC. 

In this technology is possible finding two possible processes, the direct and by transmission. The first process is use mainly in plastic films. In this case the two material are in parallel and connected by a surface and both absorbs a the same time the beam energy. The second process is the most used, mainly because the major part of plastic are transparent to the laser beam (600 to 1180 nm). To overcome this difficulty is common use additives as black carbon or lumogen or clearweld, for improving the absorption. The weld by transmission is very simple process, two materials one transparent to the laser and other with the capability of absorbing the laser, are united by pression where laser pass making the seam.

beside the laser technology, this project has also the objective of applying LEDs (light-emitting diode) and conductive polymers to the motorcycle tail light. The application of these two will help diminished the electric consumption of the lamp and also improve the flexability of the design. This flexability is acchived by the capacity of injecting the conductive polymers.
