MRJ Continuous Laser Cleaning Handheld Unit

The knob screen design of the laser cleaning tool allows users to adjust parameters directly on the handheld device without having to operate around the laser cleaning machine, greatly improving the convenience and efficiency of operation. Users only need to simply rotate the knob screen to adjust the laser energy and cleaning speed according to different cleaning needs, thereby achieving a more personalized cleaning effect.

Application scenarios: Multi-industry solutions
: Aircraft skin paint removal
During aircraft overhaul, traditional chemical paint strippers not only pollute the environment, but are also more likely to damage aviation aluminum alloy substrates. The fine mode of the MRJ-Laser handpiece can accurately strip multiple layers of paint without changing the surface grain structure of the substrate. The surface roughness after cleaning is controlled within Ra0.8μm, meeting aviation standards10. Dual red light positioning ensures uniform operation on complex curved surfaces and avoids local overheating.

Rail transit maintenance: bogie rust treatment
Train bogie rust is traditionally treated by sandblasting, which produces a large amount of waste and damages the substrate. Using the strong cleaning mode, deep rust removal of 4 bogies (area of about 15m²) can be completed in a single day, which is 2 times more efficient than sandblasting, and there is no secondary pollution. The 10-meter-long optical fiber connection design allows the equipment to operate flexibly in limited spaces7.

Precision mold maintenance: online cleaning of tire molds
The fine texture of tire molds has extremely high cleaning requirements. With a special dust cover, the mold can be directly cleaned in a high temperature environment (≤150℃) without disassembly and cooling. In fine mode, rubber residues in 0.1mm micropores can be removed, and the mold life can be extended by 3 times10.

Power facility maintenance: remote rust removal of substations
Based on the patented technology of Mai Ruijie (CN115041470A), the handpiece can be used with a 10-12m focal length galvanometer system to clean live equipment at a safe distance of 5 meters without power outage of the power station. The cleaning time of a single transformer is shortened from 2 days to 4 hours2.

Cultural heritage protection: cleaning of ancient building stones
The knob screen accurately controls the power in the range of 50-100W, and with a 0.5mm spot, it can clean the surface pollutants of stone carvings millimeter by millimeter without damaging the historical relics. In the protection project of the ancient city wall in Xi'an, the century-old dirt was successfully removed to reveal the original carving details

Laser cleaning, as the "green cleaning technology with the greatest potential in the 21st century", is accelerating the replacement of traditional polluting processes worldwide. MRJ-Laser, with its innovative design of knob screen laser cleaning tools, perfectly combines industrial practicality with cutting-edge laser technology, solving the operational efficiency pain points that have long plagued the industry.
