Laser welding of plastics is an innovative joining process that replaces traditional methods such as ultrasonic welding, vibration welding and gluing in many areas of application. It enables reproducible welding results of the highest quality and without residues such as adhesive residues \u2013 even for complicated geometries.<\/p>\n

However, until now it has been a challenge to join transparent plastics together \"invisibly\".<\/strong><\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div>

During transmission welding of two components, the laser beam penetrates the transparent joining partner and hits the laser-absorbing part. PeroLaB\u00ae<\/sup> effectively converts the absorbed laser energy (\u03bbabs<\/sub> = 800 \u2013 1200 nm, 250 \u2013 385 nm) into heat and melts the surface of the plastic.<\/p>\n\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t

The welding of light-colored or transparent plastics is particularly in demand in the textile sector or in medical technology, such as microfluidics. Compared to carbon black, it is possible to produce non-black \u2013 even transparent \u2013 weld seams with PeroLaB\u00ae<\/sup>. The color influence, especially with colored or white components, can be reduced by adding further additives.<\/p>\n\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t
