Laser engraving technology

Laser engraving technology represents a critical advancement in laser processing methodologies. It employs a high-energy density laser to locally irradiate a workpiece, thereby vaporizing or altering the color of the surface material to achieve permanent marking. This process can generate a wide variety of words, symbols, and patterns with remarkable precision.

Laser engraving machines are indispensable when speed and high precision are paramount. They are commonly utilized for electronic components, medical devices, promotional gadgets, jewelry, automotive parts, plastic buttons, hydraulic equipment, tags, and more. The laser spot's microscopic thinness allows for exceptional focus on tiny surfaces, ensuring accuracy.

The mechanism behind Ortur laser engraving machine involves a focused light beam (the spot) that interacts with the material's surface, altering its properties and appearance. This highly concentrated beam targets specific areas, enabling the laser engraving machine to create precise, high-quality, high-contrast marks. These marks are easily readable or scannable on virtually any surface, making laser engraving ideal for applications requiring exactness and permanence.

The fiber laser is the most prevalent type, effective on metals and many plastics, including its MOPA and Picosecond variants. Operating at a wavelength of 1070NM, it delivers high power to mark hard materials like metal.

Another example is the UV laser marker, which operates around 355NM. It provides lower power for marking heat-sensitive materials such as plastics and glass. UV lasers and other “cold laser” machines emit less energy, making them suitable for organic or soft products as they are less likely to burn the material. Compared to non-permanent marking methods like printing or labeling, laser engraving uses no consumables and requires minimal maintenance.

Laser engraving vaporizes materials into fumes to engrave deep, permanent marks. The laser beam functions as a chisel, removing layers from the material's surface by hitting localized areas with high energy to generate the heat necessary for vaporization.
