Imagine engraving intricate patterns on heat-sensitive resin or leaving crisp marks on delicate glass without risking material deformation. What once seemed impossible is now reality thanks to UV laser marking technology. The LW-UV series, a leader in this field, is driving a new revolution in precision manufacturing with its unique capabilities.
The LW-UV series represents a class of precision UV laser marking equipment that utilizes ultraviolet laser beams to create high-accuracy marks on various material surfaces. These systems have gained widespread adoption across industrial manufacturing, medical devices, and electronics due to their exceptional processing quality, broad material compatibility, and reliable performance. Their key advantage lies in achieving micron-level precision while enabling "cold processing" of heat-sensitive materials, preventing the damage often associated with conventional laser marking.
UV lasers typically emit wavelengths around 355nm, falling within the short-wavelength spectrum. Compared to traditional CO₂ and fiber lasers, UV lasers offer several distinct advantages:
- High Precision: The short wavelength allows for smaller focal spots, enabling micron-level accuracy ideal for marking microelectronic components or precision instrument scales.
- Material Versatility: UV laser energy is readily absorbed by diverse materials including metals, plastics, glass, ceramics, and semiconductors, eliminating frequent laser changes or parameter adjustments.
- Cold Processing: Minimal heat-affected zones (HAZ) prevent material melting, deformation, or discoloration—critical for processing thermally sensitive materials like plastics and films.
- High Contrast: Produces visibly distinct marks even in microscopic areas, essential for traceability and identification applications.
The LW-UV series comprises several key components:
- UV Laser Source: High-energy UV laser generators known for stability, longevity, and superior beam quality.
- Galvanometer Scanning System: High-speed rotating mirrors that precisely control laser movement across material surfaces.
- F-Theta Lens: Focuses laser beams uniformly across the entire working area, with multiple focal length options available.
- Control System: Advanced software managing laser operation, scanning patterns, and user interface for parameter configuration.
Additional technical features include modular design for simplified maintenance, optional red-light preview for position verification, and various accessories like rotary fixtures and protective enclosures.
- Electronics: Marking PCBs, IC chips, and device housings without damaging heat-sensitive components.
- Medical Devices: Creating high-contrast markings on surgical tools, implants, and pharmaceutical packaging.
- Precision Instruments: Engraving micrometer-accurate scales on measurement tools and optical components.
- Plastic Products: Producing durable markings on automotive parts, appliances, and consumer goods.
- Glassware: Etching intricate designs on bottles, panels, and tableware without structural compromise.
