What variances exist among laser marking machines of varying power levels?

Currently, laser marking machines (also referred to as laser inkjet printers and laser coding machines) available on the market are primarily categorized into three different types: UV laser marking machines, fiber laser marking machines, and carbon dioxide laser marking machines. Furthermore, within the same type of laser marking machine, there may be variations in power settings due to different designs and intended applications. Determining the appropriate power for the laser marking machine should be based on your specific marking requirements.

The UV laser marking machine (also known as UV laser inkjet printers) comes in various power options such as 2W, 3W, 5W, etc. These machines are primarily utilized in industries such as plastic cosmetics, QR codes, metal surface coatings, pharmaceuticals, food, PCB boards, plastic buttons, decorations, charger plugs, and more. It’s worth noting that the price of UV laser marking machines tends to increase with higher power levels.

The fiber laser marking machines are available in various power options, including 20W, 30W, 50W, 100W, etc. These machines are primarily employed in marking metals, alloys, oxides, ABS, epoxy resins, electronic components, hardware, gold and silver jewelry, glasses, watches, power switches, and more. Typically, a 20W fiber laser marking machine can achieve excellent results on most general materials.

The carbon dioxide laser marking machines are available in power options such as 10W, 30W, 60W, etc. These machines are primarily utilized for marking and cutting non-metallic materials, handicraft processing, silica gel, mobile phone composite panels, glass, leather, wood, plastics, and more. Typically, the selection of power for a carbon dioxide laser marking machine should be based on the performance requirements of the product being marked and the material of the product.

The variation in effectiveness among laser marking machines with different power levels is significant. Higher power doesn’t always guarantee superior results, nor does lower power imply ineffectiveness. It’s crucial to assess actual requirements. Lower power can be sufficient for certain applications, while higher power may be necessary for others. The choice of power depends on factors like marking depth and material. Achieving desired effects often involves proofing to confirm, and in some cases, evaluating different laser brands for suitability. Additionally, higher power machines tend to come with higher costs. It’s advisable to opt for lower power if it adequately meets requirements, rather than unnecessarily investing in higher power models.
