Currently available on the market the most widely used laser marking machine models have fiber laser marking machine, ultraviolet laser marking machine, CO2 laser marking machine, these three types of models can almost cover all kinds of products marking packaging applications. is also the current mainstream laser marking equipment.
Because of its application areas, the core components, processing principles are not the same, so the price of the model is also different, such as UV laser marking machine price near the fiber laser marking machine 3 times times as many. So below, beyond the laser small series for you to understand the difference between optical fiber and ultraviolet laser marking machine:
Laser and principle
UV Laser Marking machine: The use of 355nm ultraviolet laser research and development, this machine uses the third-order intracavity frequency doubling technology with infrared laser comparison, 355 ultraviolet light focus spot is very small, can greatly reduce the material mechanical deformation and processing heat impact
Optical fiber Laser Marking machine: The use of 1064nm wavelength.
On the wavelength of the laser, the shorter the general wavelength, the laser beam out of the smaller, precision will be high, processing of the formation of the heat affected area will be smaller, processing the more exquisite effect. There is the UV laser marking machine processing methods and other laser marking equipment differences, generally for CO2 laser marking machine, fiber laser marking machine, are used for laser physical marking method, and ultraviolet laser marking machine is a chemical processing method, mainly photochemical reaction to processing, The difference between the two different processing methods is that the laser physics processing method is mainly in the product and material surface processing, and the laser chemistry processing method can use the laser depth to the product material internal processing.
