In 2012, the fiber laser cutting equipment popular competition was 2000 watts of power, in 2014 it was 3000-4000 watts, many people think that 4 kW can meet most of the thickness of sheet metal cutting processing needs. However, by the second half of 2016, the Dazu Laser first introduced an 8 kW machine, which triggered a new-round high-power laser cutting. Today, major laser cutting manufacturers are already competing for 12,000 watts and 15,000 watts of power. I have to admit that the upgrading of laser products is very rapid, and the market development is changing rapidly.
In 2017, the global laser processing equipment market was 31.37 billion US dollars, an increase of 12%. In 2001, the total sales volume of China's laser equipment market exceeded 44.2 billion yuan, and laser cutting equipment accounted for 46% of the national industrial laser processing equipment market. Among them, the sales volume of medium and small power laser cutting equipment has maintained a high growth rate, and its core laser has achieved a high localization rate. While the laser cutting equipment market is growing at a high speed, air compressors that provide auxiliary gas sources for laser cutting machines have also attracted attention.
The laser cutting machine can cope with the cutting requirements of various materials and complex shapes. In addition to the laser that can provide high energy, the auxiliary gas is an indispensable material for cutting. The auxiliary gases used for laser cutting are mainly oxygen (O2), nitrogen (N2) and compressed air (Compressed Air). Its main function is - cooling to prevent material hardening, that is, heat treatment; second, the pressurized gas blows off the molten metal slag to prevent dust from clogging the laser nozzle, protecting and prolonging its service life.
