Transmission welding of plastics using lasers is one of the fastestgrowing direct diode applications today. This blind overlap
technique joins a laser-transparent surface plastic to a base
absorbing plastic. The result is a hidden weld which is as strong
as the base material itself with the surface material remaining
perfectly intact.Advantages Using Direct Diode Lasers
֕Non contact, clean welding -no abraded particles Reduced heat input reduces thermo mechanical stressՖavoids damaging integrated electronic componentsTransmissive (surface) exposed plastic retains appearanceand surface qualityՕHighest quality, hermetically sealed joints Highest efficiency compared with other laser based techniques
The transmission (red line) and reflective (blue line)characteristics required for transmission welding of
plastics are an ideal match to the output wavelength of
direct diode lasers.
