Choosing the right laser marking machine power requires comprehensive consideration of the following multiple factors:


Marking materials
Metal materials: for higher hardness of metals such as stainless steel, titanium alloys, etc., generally require higher power, usually 30W or higher fibre laser marking machine is more appropriate; for aluminium, copper and other relatively soft metals, you can appropriately reduce the power, 20W or so of the fibre laser marking machine is often able to achieve better results. Such as automotive parts manufacturing, stainless steel engine casing marking, often use 30W-50W fibre laser marking machine; and aluminium alloy wheel marking, 20W-30W power can be.
Non-metallic materials: plastics are more sensitive to laser power, generally 10W-20W low-power laser marking machine is sufficient, such as cosmetic plastic bottle marking, commonly used 10W or so of the ultraviolet laser marking machine; wood is usually low to medium power can be used, depending on the depth of the marking and the effect of the surface of wooden furniture, such as shallow decorative marking, 10W-30W carbon dioxide laser marking machine is more suitable; glass marking, glass, glass, glass, glass, glass, glass, glass, glass and other materials, such as wood, wood and other materials, such as wood, wood and other materials. Marking of glass requires low power, but the pulse frequency and speed adjustment is very important, otherwise it may lead to glass rupture or cracks, general 5W-10W UV laser marking machine can meet most of the glass marking needs.
Marking depth requirements
Shallow marking: If only shallow engraving or marking on the surface of the material, such as marking the brand logo, model number and other information on the shell of electronic products, the depth requirement is not high, this time, you can choose a lower power laser marking machine, such as 20W fibre laser marking machine for the metal casing, 10W UV laser marking machine for the plastic casing, etc., not only to meet the requirements of the marking clarity, and can reduce equipment costs and energy consumption. Energy consumption.
Deep marking: When deeper marking effects are required, such as engraving scales, patterns, etc. on metal moulds, or deep engraving on stone, the power needs to be increased. Generally speaking, for metal materials, it may need 50W-100W or even higher power fibre laser marking machine; for non-metallic materials such as stone, wood, etc., 30W-50W carbon dioxide laser marking machine may be more appropriate. At the same time, depth marking also need to reduce the marking speed to ensure that the laser has enough time to act on the surface of the material, so as to obtain the ideal depth effect.
Marking speed requirements
High-speed marking: If the production task requires high marking speed, hope to complete a large number of products in a short period of time marking work, such as in food, pharmaceuticals and other large-scale production of packaging marking date of production, batch number and other information, you need to choose a higher power of the laser marking machine. Because the greater the power, the faster the marking speed, such as 50W-100W fibre laser marking machine or carbon dioxide laser marking machine can meet the needs of high-speed marking, but the corresponding cost of equipment and energy consumption will also increase.
Low-speed marking: for some of the marking speed requirements are not high occasions, such as small quantities of custom products marking, crafts personalised engraving, etc., you can choose a lower power laser marking machine, in order to ensure that the marking quality under the premise of reducing the investment in equipment and operating costs.
Marking precision requirements
High-precision marking: For some applications that require high-precision marking, such as electronic components, PCB boards, semiconductor chips and other marking, as well as tiny text, pattern engraving, usually need to choose a short-wavelength, high-energy density ultraviolet laser marking machine, whose power is generally in the 3W-10W between. UV laser spot diameter is small, high focusing accuracy, can achieve very fine marking effect, but the price of equipment is relatively high.
General precision marking: If the marking precision requirements are not particularly demanding, such as the marking of common industrial products, building materials marking, etc., you can choose a fibre laser marking machine or carbon dioxide laser marking machine, according to the material and marking depth, speed and other requirements to choose the appropriate power, generally 20W-50W power range to meet the majority of the general accuracy of the marking needs!
