    description

    Laser engraving is one of the most versatile technologies for material processing. The ability to process a wide range of materials gives lasers the advantage over other conventional processes. Lasers have become the preferred choice for many industrial processing applications, and they have been well accepted in a wide range of industries from direct part marking in the automotive industry, to surface paint removal in the aerospace industry; to thin and thick sheet metal cutting in the fabrication industry; to surface decoration; to the solar industry and everything in between.
