CO2 Laser coding solution is use high energy density aggregation in carved the underlying surface, within a very short period of time make the surface of biomass gasification by controlling the effective displacement of the laser beam, precisely burning and carving out exquisite patterns or characters. Reduce production costs, no consumption, high efficiency, permanent mark to ensure that the product can be traced back. Enhance the additional value and brand effect. Performance is more stable, work continuously for 24 hours and the maintenance time of the laser is more than 100,000 hours. Environmentally friendly non-toxic and no noise pollution.
