Laser Plastic Welding
 
The Process:
Transmission laser welding creates a perfect and reliable connection. In this process, two plastic parts are joined, each possessing different absorptive characteristics. The laser penetrates the top layer, which is transparent to that wavelength, but is absorbed by the bottom layer. The surface of the bottom layer melts, which in turn melts the adjoining surfaces of the top layer and both surfaces bind to each other

Clean and safe joining of components
Welding plastics via laser is especially suited for delicate components, because there is no mechanical motion and the thermal reaction is minimal. This makes the technique ideal for a wider range of possible applications in such industries as automotive, medical, consumer electronics, and the food industry.
