Alumina Laser Blackening With Mopa Laser

- Oct 09, 2018 -

Metal black is generally for stainless steel, stainless steel is black, and general laser marking machines can do it. Semiconductor laser marking machines and fiber laser marking machines can do this. But for aluminum, the situation is different. Aluminum can be gray or black, but it can't be darker. In fact, it is a special fiber laser marking machine that can really blacken aluminum. It uses a laser-powered special fiber laser to output laser. The electro-optical conversion rate is high, the volume is small, and the beam quality is good.

The alumina black laser marking machine is different from the ordinary fiber laser marking machine. This laser marking machine adopts the pulse width adjustable mode, that is, the Mopa laser. The maximum frequency can be adjusted to 400Khz, and the aluminum material can be directly black. The effect, magnesium aluminum, aluminum oxide, all kinds of aluminum are common, the current Apple mobile phone shell on the market or the small characters behind the iPad shell are made with this fiber laser marking machine.

Advantages of special fiber laser marking machine for alumina blackening

1. The air-cooled device, smaller size and easier installation

2. The laser beam is thin, the processing material consumption is small, and the processing heat affected zone is small.

3. High processing efficiency, computer control, easy to automate

4. Marking is clearer and more beautiful, in areas with high requirements for depth, smoothness and fineness

5. The laser output power is stable and the reliability is high, which meets the production requirements of 24-hour continuous stable processing.

6. The life of the whole machine is about 100,000 hours.

7. Place the product on the desktop to work statically, mark the product, and mark the dynamic online flight of the mobile product.

8. Support rotating 360 degree markings.
