| Features: 1. High power: 20W whole electrical power, pulse peak optical power can reach 20000W. 2. Wide applicability: M4 marking machine uses 1064nm wavelength infrared light source, which is suitable for fast marking on all metals and ABS, and marking precious metals hardly consumes precious metals themselves. Specific materials: common metals and alloys (all metals such as iron, copper, aluminum, magnesium, zinc, etc.), rare metals and alloys (gold, silver, titanium), metal oxides (all kinds of metal oxides are acceptable), special surface treatment (phosphating, aluminum anodizing, electroplating surface), ABS material (electrical appliance shell, daily necessities), ink | |
