Ablative coating

Ablative Coating Removal Systems

The Coating Removal Systems use laser light to ablate or evaporate thin surface layers of paint, contaminants, rust or residual materials left from previous processes. Based on IPG’s Robotic Laser Workcell, the Coating Removal Systems comprise a pulsed fiber laser optimized for material ablation, IPG's proprietary large-area scanning head and fume extraction/debris removal module integrated with an industrial 6-axis robot. In the standard Coating Removal Systems, the robot and process delivery units are packaged within a Class 1 laser safe enclosure, with full interlock integration with access doors and facilities safety systems. IPG also offers custom design services to integrate the laser and cleaning modules with robotic and Cartesian precision motion systems, gantries and AGV’s to accommodate parts ranging from engine components up to large airframes.

Coating Removal Systems are designed for removing paint, rust, mold coatings and contaminants from complex-shaped parts. High-efficiency laser removes successive thin layers of material until the desired underlying coating or bare surface of the part is exposed. Unlike abrasive material blasting, with laser ablation the position of the laser beam is precisely controlled to ablate only the target area, eliminating the need for time-consuming part-masking. The ablated particles and vapor are collected by the integral vacuum debris collection unit, eliminating the need to separate toxic elements from the abrasive material and dramatically reducing the waste material disposal. IPG’s ablation lasers include high average power high peak energy lasers optimized for high throughput at minimal heat transferred into underlying substrates.
