Laser Cleaning

Laser paint removal, also known as laser paint stripping, is a modern surface treatment technology that relies on laser radiation. With advantages such as environmental friendliness and precision, it is gradually replacing traditional paint removal methods in multiple industrial fields. The core lies in the laser ablation or photothermal ablation effect. The laser equipment emits pulsed laser beams of specific wavelengths onto the painted surface. The paint coating absorbs the laser energy and heats up rapidly. Within a short period of time, evaporation and sublimation occur. Some of them may also form plasma due to energy accumulation and generate shock waves, causing the paint layer to crack and fall off. Meanwhile, the paint mist and fine dust generated during the process can be promptly removed by the accompanying vacuum cleaner or exhaust system. Moreover, by adjusting parameters such as the power and pulse width of the laser, the energy density can be precisely controlled to ensure that it only acts on the paint layer and avoid damaging the substrate.

Core advantage:

Environmentally friendly and pollution-free: No chemical paint removers, sandblasting abrasives or other consumables are needed. It will not produce chemical waste liquid to pollute the soil and water sources. The small amount of dust generated can also be collected and treated by the equipment, having a minimal impact on the environment and the health of operators. Precise and controllable: It can achieve micron-level paint removal accuracy, specifically removing paint from specific areas without affecting the surrounding coatings. This controllability makes it suitable for processing workpieces with fine structures, and the paint removal effect is stable, allowing for repeated operations and meeting the demands of industrial batch production. Contactless and non-damaging: The entire process does not require mechanical tools to come into contact with the workpiece surface, avoiding problems such as substrate scratches and deformations caused by traditional methods like sandblasting and scraper grinding. It is particularly friendly to fragile or valuable substrates such as aluminum alloys and precision instruments. Low long-term cost: Although the initial investment in the equipment is relatively high, it only consumes electricity during subsequent operation, with no consumable loss. Moreover, the equipment requires less maintenance. Compared with the traditional paint removal method that frequently replaces consumables, it has a more advantageous overall cost over long-term use.
