Laser welding parts made of plastics is an entirely new technology. The laser superheats the polymer and does not require physical contact. The beam of infrared is directed at the polymer. Directly towards the weld joint. You do this by passing through one of the components. Commonly known as, through transmission
The laser can direct an infrared beam (infrared light) at the joint to weld parts. The infrared beam (usually a laser) is used to heat the part through the joint and absorb the light at the surface.
Monochromatic lasers, which can be used to heat small areas of the parts, are faster than broad-band infrared beams. This allows for very rapid welding, with very few changes to the geometry. If you want you can get the best welding service of laser from Proto Lase in Maple Grove.

Laser machining is an example of electromagnetic plastic machining. After the radiant energy has been directed towards the polymer surface, there will be three things that happen to it: most of it transmits through, some of it is absorbed and some of it is reflected.
Infrared light is directed through one part of the parts to the weld joint. This is called the application process. The part that transmits the most energy will not heat. However, the absorbing part will superheat.
Some dyes and fillers, such as carbon black, are used. To absorb energy at the interface of weld joints. This is also known as laser or through transmission infrared stamping parts. When materials are heated to a melting point and fused, stamping is done.
The laser light must be transmitted by one material and absorbed by the other. Both materials will convert it to heat. The materials must be transmissive. All of this depends on the formulation of pigment.
