Laser marking plastics, glass and other heat-sensitive materials can present particular challenges. Excessive heat input can cause discoloration, deformation or cracking, while marking curved or uneven surfaces requires the laser beam to remain precisely focused throughout the marking process.
TYKMA Electrox Zetalase™ XL UV 3D combines UV laser technology with dynamic 3D focusing and is designed for permanent, high-precision marking with minimal thermal impact on the material.
UV laser for minimal heat impact
The system uses a 355 nm UV laser. Its short wavelength enables a photochemical process with very little heat transferred to the surrounding material – often referred to as cold marking.
This is particularly valuable when marking materials where conventional laser processing could cause melting, deformation, discoloration or microcracking.
The technology is particularly suitable for:
- sensitive plastics and polymers
- glass and transparent materials
- electronics and printed circuit boards
- medical devices and components
- sensors and optical components
- small components requiring extremely fine details.
The result is permanent, high-contrast marking with a very small heat-affected zone.
Dynamic 3D focusing
One of the key features of the Zetalase XL UV 3D is its dynamic focusing system.
Unlike a conventional 2D system, the laser focus can automatically adapt to the geometry of the component. With a 40 mm dynamic focus range, the system can maintain accurate focus across curved, angled, stepped or otherwise three-dimensional surfaces.
The component’s 3D geometry can be imported using an STL file, allowing the system to adapt the marking to the shape of the surface and compensate for optical distortion.
This enables text, graphics, serial numbers, barcodes and Data Matrix codes to be marked with consistent quality even when the marking extends across different height levels.
High detail for demanding applications
The combination of the UV laser’s short wavelength and dynamic 3D focusing makes the technology particularly suitable for applications involving both very fine details and complex geometries.
One example is the medical device industry, where permanent UDI marking may be required on small components and medical-grade plastics without adversely affecting the properties of the material.
In the electronics industry, the technology can also be used to produce extremely small, high-contrast markings on components where heat input must be kept to an absolute minimum.
Designed for industrial production
Zetalase XL UV 3D is a fully enclosed laser system designed for industrial production. The system can also be configured for automated manufacturing and integrated with equipment such as robots and conveyor systems.
This makes the technology suitable both as a stand-alone marking system and as part of a larger automated production solution.
