Industrial Laser Marking Machines on FindLight

Did You Know?

Laser marking machines are Computer Numerical Controlled (CNC) laser machines to create permanent high contrast marks on a number of different materials and surfaces. These laser system typically come with a CO2 or a fiber laser source, although DPSS (Nd: YAG , Nd: YVO4, etc.) lasers are also prevalent. Laser marking machines are used in a number of applications to create different types of graphics, texts (alphanumeric), barcodes, logos, even photos printed on various 2D and 3D surfaces. A Laser marking machine will usually come either with galvo scanner head or as a flatbed system. In galvo scanner based laser marking systems a pair of galvo scanner steers the laser beam using two mirrors towards an F-theta lens which focuses the beam onto the sample being marked. Similarly, in a flatbed system, a pair of mirrors steer the beam using linear motion on an XY plane. In such system, travel along the Z-axis is used to position the object inside the laser marker. Complex 3D and 4D laser marking systems can mark on uneven 3D reliefs and even create 3D marks in glass objects. Laser marking is a mature engineering process that has been adopted by many industries and application including, home improvement, hobby, awards and engraving, manufacturing, automotive parts marking, coding and serializing on a variety of materials, including metals, glass, plastics and stones. Laser marking offers many advantages over traditional marking technologies such as inkjet printing, hot stamping, etc. Marks created by laser marking are a lot more precise, durable and high contrast. The process is also very quick and environmentally friendly.

Frequently Asked Questions

Laser marking technology leaves permanent marks on various surfaces using a focused beam of light at relatively high power levels. The laser is typically steered either by a pair of linearly moving mirrors or galvo scanning mirrors that steer the beam of light. When focused on a substrate, the laser energy is released into the material. When the light beam interacts with the surface of the component, heat energy is transferred from the beam to the surface. As a result, the material's appearance and properties change. The exact mechanism of laser matter interaction during laser marking depends on a number of factors including the laser output parameters, the material being marked and the existence/absence of a laser marking ink (additive). Depending on these factors a laser machine can engrave, mark, etch, anneal, or discolor surfaces.

Overview of Laser Marking Machines

Laser Marking Machines are non-contact systems that use focused laser beams to create high-contrast, permanent marks on metals, plastics, ceramics, and composites. On FindLight you can source a range of laser marking machines based on wavelength, power, and beam delivery configuration to integrate into production lines or R&D workcells.

Typical Architectures and Specifications

Most Laser Marking Machines on FindLight employ fiber, CO2, or DPSS solid-state light sources, with common wavelengths at 10.6 µm (CO2), 1064 nm (fiber/ND:YAG), 532 nm (green), and 355 nm (UV). Output power typically ranges from 5 W to 100 W for general marking, with higher powers available for deep engraving. Many systems offer pulsed operation (nanosecond or picosecond) for precise heat control, high peak power, and minimal thermal damage.

Beam delivery is usually via galvo-scanning heads with F-theta lenses, defining a marking field such as 100×100 mm, 200×200 mm, or larger. Key specifications for Laser Marking Machines include marking speed (up to several thousand mm/s), spot size, positioning accuracy, repeatability, and supported file formats (DXF, PLT, BMP, etc.). Cooling can be air or water, and control is commonly via industrial PCs or embedded controllers with I/O for automation.

Use Cases for Laser Marking Machines

Laser Marking Machines are used for serial numbers, barcodes, QR codes, UID, logos, and functional text on metals (stainless steel, aluminum, titanium), engineering plastics, printed circuit boards, medical devices, and automotive components. UV and green laser marking machines are preferred for delicate polymers, glass, and electronics where low heat input is required. Deep engraving configurations are used for tooling, molds, and traceability in harsh environments.

Buyer Guidance on FindLight

When evaluating Laser Marking Machines on FindLight, compare:

  • Wavelength and laser type: Match to substrate (fiber for metals, CO2 for organics, UV/green for sensitive materials).
  • Average power and pulse parameters: Determine throughput, marking depth, and thermal impact.
  • Marking field and mechanics: Check working area, Z-adjustment range, and enclosure or open-frame design.
  • Integration and control: Assess software, CAD/CAM workflow, and automation interfaces (I/O, fieldbus, safety circuits).
