Different materials have different absorption rates for different "light wavelengths", so laser cleaning utilizes this physical property to produce.

Laser cleaning is the use of high-frequency and high-energy laser pulses to irradiate the cleaned surface. Materials suitable for absorption will instantly absorb the focused laser energy and generate shock waves, causing oil stains, rust spots, or coatings on the surface to evaporate or peel off instantly.

It can quickly clean surface attachments or surface coatings, and the energy of light is emitted in a short time. After adjusting the usage parameters, it basically does not harm the metal substrate. However, the heat generated by the laser can also cause the surface of metal parts to heat up and absorb heat. If it is some steel, it may lead to annealing. Of course, if it is a part in use, it can also eliminate internal stress in the metal, The benefits of reducing mechanical fatigue.

Laser cleaning can be used in steel, cast iron, non-ferrous metals, rubber product materials, etc., with a wide range of applicability. It has been successfully used in shipbuilding, automotive production, tire molds, aviation, military industrial facilities, engineering machinery, 3C electronics, petrochemical energy, and cultural relics.

The application of laser cleaning can be traced back to 2017, and multiple manufacturers have been producing and shipping in Shenzhen. At that time, the price of lasers was relatively high, and the surrounding supporting equipment was not yet mature, resulting in a high cost of complete equipment. For example, the price of the embedded chiller at that time was twice that of today! At that time, the annual shipment of Dafang Refrigeration was within dozens, which was indeed small in quantity and high in price.

With the significant price adjustment of lasers last year and the optimization of surrounding supporting costs, the cost of complete sets has also been reduced to an acceptable range for some small and medium-sized enterprises, resulting in an increase in market shipments.

The laser power range has also evolved from the original maximum of 500W to the current 2000W. With higher power, the application range has become wider and wider, and efficiency has also been improved. Especially during the pandemic, due to the shortage of manpower, laser cleaning has replaced many low-cost and intensive workstations.
