Laser marking machines are a permanent process that uses a concentrated beam of light to create a long-term mark on a surface. Laser engraving is generally done with fiber optic, pulsed, continuous wave, green or UV laser machines for a wide range of applications. Laser marking machines can automate, solve at high speed, and mark steel, titanium, aluminum, copper, porcelain, plastic, glass, wood, paper, aluminum, copper, porcelain, plastic, glass, wood, paper and cardboard. Parts and products can be marked with text (including serial and part numbers); device-readable data (such as bar codes, unique ID codes and 2D data matrix codes); or graphics. How Laser Marking Machines Work Laser marking machines work by marking a focused beam on the surface of the workpiece. As the beam interacts with the surface of the part, it changes the properties and appearance of the plastic. This intense beam looks at only specific areas, allowing the laser engraver to create accurate, high-quality, high-contrast marks that are easy to read or scan on virtually any surface. This feature makes laser engraving the best choice for success. Laser markers do not use consumables and require less maintenance than other non-permanent marking processes, such as printing or signs. How do laser markers work? There are many different types of laser marking machine systems, each with different modes of operation. The correct process for applying the equipment also depends on the material and application you are using. Advantages of laser marking machine applications Manufacturers can gain many benefits from the laser engraving process, whether it is basic part identification and marking, or complete traceability to track and trace parts from birth to death. Laser marking machines can provide long-lasting and readable marks.
