Factors affecting laser marking depth

● Laser power: The power of the laser marking machine determines its energy input to the material. Generally speaking, the higher the laser power, the greater the marking depth.

● Material type: Different materials have different absorption rates of laser, which will affect the propagation and energy conversion of laser within the material, thus affecting the marking depth.

● Laser wavelength: Laser wavelength also affects the absorption of laser in materials. Some materials have better absorption properties for lasers of specific wavelengths, which may produce deeper markings.

● Focal length and focus: The focal length of the laser marking machine and the degree of focus will affect the focus of the laser energy, which in turn affects the marking depth.

● Marking speed: When the marking speed is fast, the time for the laser to illuminate the same point per unit time is short, and the laser energy may move before it is completely transmitted to the material surface, thus affecting the marking depth.

Application materials of laser marking depth

Suitable for working with most metal marking applications such as gold, silver, stainless steel,

brass, aluminium, steel, Iron titanium etc, and can also mark on many nonmetal materials,such as ABS, Nylon, PES, PVC etc.

Application industry of laser marking depth

Widely used in jewelry, hardware accessories, plastic transparent keys, IC chips, digital product components, precision machinery, sanitary ware, measuring tools and cutting tools, clocks and glasses, electrical appliances, electronic components, hardware accessories, hardware tools, mobile phone communication components, automotive Motorcycle accessories, plastic products, U disks, computer keyboards, batteries, electronics, communications, electrical appliances, instruments, tools, precision instruments, accessories, etc.
