UV Laser Marking Machine

UV Laser Marking Machine

The MRJ-Laser UV Laser Marking Machine is a high-precision marking system utilizing a 355 nm UV "cold light" source to mark sensitive materials like glass, plastics, and ceramics without thermal stress. Available in low-power configurations 3 W to 10 W, it is the ideal solution for high-quality, permanent, and detailed marking required in the electronics, medical, and high-end packaging industries.

UV Laser Marking Machine – Precision Through Cold Processing

The UV Laser Marking Machine stands out for its short wavelength (355 nm), which enables the laser to break molecular bonds within the material instead of melting or vaporizing it. This process, known as β€œcold processing,” minimizes thermal impact β€” preventing deformation, cracking, or micro-fissures, particularly in delicate or heat-sensitive materials.

Key Features and Applications

1. Cold Marking Technology
Employs a non-thermal marking process that eliminates heat effects, resulting in ultra-fine, smooth, and burr-free marks. Ideal for substrates that are easily damaged by heat.

2. High Beam Quality
Generates an exceptionally small focused spot, enabling high-definition engraving, intricate patterns, and microscopic text or logos.

3. Specialized Glass Marking
Highly effective for marking and engraving various types of glass, including bottles, crystals, and decorative glassware, as well as ceramics and silicon wafers.

4. Versatile Material Compatibility
The UV laser is widely used across industries for its ability to produce clean, high-contrast marks on a range of materials:

  • Plastics: HDPE, PVC, ABS, Nylon β€” ideal for marking white and coloured plastics.
  • Electronics: Precision marking and micro-cutting on FPCs, PCBs, and other electronic components.
  • Medical Devices: Marking on plastics and polymer-based instruments that must withstand sterilization processes.
