In the field of laser processing, laser marking technology stands out as a crucial application. Several types of laser marking machines are commonly available, including CO2 laser marking machines, diode-pumped side-excited laser marking machines, diode-pumped end-excited laser marking machines, and fiber laser marking machines. But what exactly differentiates these four types of laser marking machines?
Let’s explore the distinguishing features of each type of laser marking machine:
CO2 Laser Marking Machines: These laser marking machines typically utilize imported CO2 radio frequency (RF) lasers, boasting a lifespan of 20,000 to 40,000 hours. They offer high-speed marking, reaching up to 7000mm/s. CO2 laser marking machines are particularly well-suited for marking on a wide range of non-metallic materials, such as paper packaging, plastic products, leather fabrics, glass, and ceramics.
Diode-Pumped Side-Excited Laser Marking Machines: These laser marking machines employ an integrated modular diode laser design, replacing the krypton lamps found in traditional YAG laser marking machines. This eliminates the need for frequent lamp replacements. The modular design also contributes to a lower failure rate and easier maintenance. Diode-pumped side-excited laser marking machines offer excellent beam quality and are suitable for marking on various metallic and non-metallic materials, including plastics, mobile phone buttons, and stainless steel.
Diode-Pumped End-Excited Laser Marking Machines: Based on laser wavelength, diode-pumped end-excited laser marking machines can be further categorized into infrared (IR) laser marking machines, green laser marking machines, and ultraviolet (UV) laser marking machines.
Fiber Laser Marking Machines: These laser marking machines incorporate imported lasers, equipped with high-speed galvanometer scanning systems and professional laser marking software. With the decreasing cost of fiber lasers, fiber laser marking machines are becoming increasingly mainstream. Due to the modular design and integrated air-cooling system of fiber lasers, fiber laser marking machines are generally more compact compared to other types of laser marking machines.
This detailed comparison should help in understanding the nuances between the different types of laser marking machines available on the market.
