You can see some jewelry shop mark letters and pictures on ring, bangle,bracelet and some round parts, Have you ever think to get a machine for your shop. But how to do it by a fiber laser machine? Let’s talk about it.
In general speaking, almost jewelry owner will mark on gold, silver, brass and stainless steel.
But engrave on stainless steel and gold, silver, there are different way to engrave. Because the soft metal and hard metal with different nature of the metal,according their nature, we need to find different way to get color mark on them.
In our general industry experience,there are two ways to get letters on different metal.
Stainless steel engrave.
Stainless steel and iron steel,carbon steel, they are hard metal,so for stainless steel engrave, we can not engrave it well when laser on the focus.so the best way to solve with it is make the focus to up around 7mm from the real focus. Input the low power, slow speed,Then we can get great black color on stainless steel.

For the Gold, silver and some soft metal,we will need another way to get black on metal.
We just make the focus on its right position, then we can get black. For titanium,it can get all kinds of color by a normal 2D non mopa machine.

In a word, fiber laser marking machine to mark some letters is a easy work, a normal fiber laser machine can do it well, if you mainly do the mark and engrave work. In theory, all metal can be mark, just we need to control the parameter, also,The potential of the machine is endless,We can also have an exploratory heart to develop more potential of fiber laser machines.
