Laser cleaning equipment mainly contains the laser, control system, cleaning head and other core components, the laser is mainly used in the pulse laser. At present, the domestic pulse laser power level is still far below the continuous laser, pulse laser technology has a lot of room for improvement. And the increase in power of the pulse laser is also required for high power large area laser cleaning applications; In addition, the performance of other device parameters are still in the upgrading stage, requiring a breakthrough by colleagues from all parts of the industry chain. Therefore, there is still a long way to go before domestic laser cleaning equipment becomes popular in the market.
As the core component of laser cleaning equipment, the laser must bear the brunt of the development process and take the lead in improving the technology and power level of lasers used for laser cleaning, and MAX Laser, as the head of the domestic fiber laser enterprises, is naturally obliged to take up this important task.In 2016, MAX Laser has started to enter the research of laser cleaning application field, and has launched industry-leading laser cleaning solutions such as handheld cleaning and backpack cleaning, and has become one of the first manufacturers to develop and launch laser cleaning solutions in China. With a long and continuous in-depth research in the field of laser cleaning application and 17 years of laser technology accumulation, MAX Laser has launched 500W-1000W MOPA pulse fiber laser for laser cleaning, which can be applied to rail transportation, shipbuilding, automobile manufacturing, mould and other industries.
The main advantages of the Mopa 500W-1000W are: a variety of pulse waveform options to meet different materials cleaning; high single pulse energy, high cleaning efficiency; spot energy uniform distribution, cleaning without harming the substrate; chassis structure for easy integration; long output cable, large processing width.
With hundreds of millions of tyres manufactured worldwide each year, the cleaning of tyre moulds during production must be quick and reliable to save downtime. Traditional cleaning methods take a long time and can easily damage the accuracy of the moulds, creating safety and environmental concerns.
In contrast, with laser cleaning it takes only 2 hours to clean a set of large tyre moulds on the production line. The cleaning cycle depends on the frequency of use, generally in full production (three shifts), continuous use, at least once a month cleaning, compared with the traditional sandblasting method, laser cleaning efficiency can be increased by 10 times, now it is used in large numbers in the production of tyres in Europe and the US.
According to the "Medium and Long-term Railway Network Planning" released by the National Development and Reform Commission, the scale of China's railway network reached 150,000 kilometres in 2020; by 2025, the scale of the railway network will reach about 175,000 kilometres. China has the world's largest high-speed rail network, and laser cleaning has a wide range of application scenarios in the manufacturing, maintenance and repair of rail transit (Metro, urban rail, high-speed rail, multiple units, ordinary trains, etc.).
In the manufacturing of new rail vehicles, the use of laser cleaning off the impurities/oxidation layer on the raw material of the plate before welding the body, the welding is better formed and more solid; after welding the body and then using laser cleaning of the welding channel weld marks, can make the body appearance more clean and flat, can strongly promote the refinement of rail vehicle manufacturing, intelligent.
After the railway is put into operation, the track is easily rusted by the wind and rain all year round, so the railway authorities need to remove rust from the track regularly to ensure the smooth running of trains, the traditional cleaning method is inefficient, labour-intensive, uneven cleaning effect, and easy to cause dust scattering and noise pollution. Using laser cleaning method, the thickness is precisely controlled and the cleaning quality is uniform, which not only improves the surface cleanliness of the rail, but also preserves the curved surface shape of the rail, reduces damage to the base material, eliminates dust pollution, reduces cleaning costs and improves the working environment of workers.
With the breakthrough of laser technology and process, as well as in the application field of continuous development, the future laser cleaning industry will be a cluster of industrialized explosive demand growth, replace more traditional cleaning market, become the mainstream choice of industrial cleaning!
