LASER PLASTIC WELDING Rotation Optic Integratable optical unit for sequential welding of components with rotational symmetry

Laser Plastic Welding Established in 1998, the Leister business unit has many years of experience in laser welding of plastics. Leister is the owner of a number of patents (such as Mask or GLOBO welding) and the only company with expertise in all standard laser plastic welding techniques. The principle of laser welding Joining pressure In laser welding of thermoplastics, sometimes referred to as “laser transmission welding” or “through transmission IR welding” (TTIr), transparent and absorbent parts are bonded together. The laser beam penetrates the transparent plastic and is converted to heat...

Rotation Optic Using simultaneous horizontal deflection and rotor rotation, the beam creates a plane in which shape and position of the welding seam are independent of the diameter of the components. The parts must be centered within the rotation axis in any case. For every deviating deflection, the radiation forms a cone in which the welding seam appears as a wave shape when components are decentered. The last deflection mirror determines the spatial position of the radiation. The mirror can be moved 5° up from the horizontal and around 75° down. This makes it possible to access difficult-to-reach...
