Today DOWIN will describe the differences between different types of laser marking machines and how to choose. First of all, laser marking machines are divided into three different laser types: fiber, CO2 and UV. The specific differences will be explained below.
Dowin fiber laser marking machine can work on all metal sheet, and some non-meal materials, such as stone, plastic, leather, coated wood…. And bigger power, such as 60W/100W, also can cut thin metal sheet (around 1mm), also can color mark on stainless steel, and brass.
But it cannot mark on wood, acrylic, glass, etc.
