Technical Parameter

How does alumina print black logo?

Alumina blackening, in our life, it is more common is iPhone, iPad, other brands of mobile phone aluminum back cover for logo and text blackening, this blackening effect is marked with Laser Marking Machine, as well as a variety of mobile phone accessories, watches, molds and other products trademark, logo, batch number blackening and so on. Therefore, the demand for alumina blackening is still very large, and many customers are asking related questions, such as uneven pattern blackness, not black enough, and not fast.

Metal blackening is generally for stainless-steel. Stainless-steel blackening, the general laser marking machine can do, semiconductor laser marking machine, Fiber Laser Marking Machine can do these. But for aluminum, the situation is different, aluminum can be played gray or black gray, but cannot play blacker, copper cannot play too black, can play clear is very good. So which machine is the right one to use?

Ordinary laser marking machine on aluminum products can only play gray or black gray text information, it can really black aluminum is a special fiber laser marking machine, also known as the full pulse width laser marking machine. This laser marking machine can directly hit the aluminum black effect, magnesium aluminum, alumina, all kinds of aluminum are common, the current market iphone shell or ipad shell behind the small words are useful this fiber laser marking machine made.

The principle of full pulse width laser marking machine is the use of laser blackening special fiber laser output laser, electro-optical conversion rate is high, small size, good beam quality; With adjustable pulse width mode, the frequency can be adjusted to 400Khz, and the aluminum can be directly hit the black effect. Therefore, relatively speaking, the price of the full pulse width laser marking machine will be higher than that of the ordinary laser marking machine.

Aluminum laser marking machine, aluminum black, first of all, there is a necessary condition is to be oxidized aluminum can be added to a black. The mechanism of anodized alumina blackening is to further oxidize the anodized alumina layer with a film thickness of 5-20um in a very short time and change the mechanism of the surface material by focusing the laser with high energy density. Black and white mainly rely on focus, power, speed, density, these four convenient regulations. Beginners can practice and master it many times.

In actual operation, affected by the purity of the material, the specific value will also change, the above 5 values, a little change will produce completely different results, so in actual operation, we also need to carry out the corresponding test adjustment according to the final effect.
