As daily necessities with both practicality and artistic value, glass cups have increasingly refined and personalized surface decoration requirements. Traditional manual engraving or mechanical processing has problems such as low efficiency, easy breakage, and single pattern. UV laser marking technology, with its "cold processing" characteristics and ultra-high precision, provides a revolutionary solution for glass decoration, promoting the industry to upgrade to intelligent and artistic directions.

 

The UV laser marking machine uses a 355nm short-wavelength laser to directly destroy the material molecular chain through photon energy, generating almost no heat, avoiding cracks or deformation of the glass caused by thermal stress, and realizing "cold processing". Its spot diameter can be controlled at the micron level, and the minimum character accuracy is 0.2mm. It can engrave complex patterns, LOGO or text on curved, cylindrical or special-shaped glass cups, with clear edges and no burrs, high contrast, and no chemical residue. For example, Chuangke Laser's 3D UV Laser Marking Machine solves the problem of font deformation in curved surface engraving through three-axis dynamic focusing technology, and supports high-precision processing of complex surfaces such as steps and slopes.

 

For example, curved glass products such as red wine glasses and champagne glasses can be engraved with embossed patterns, brand logos or customized patterns through UV laser, giving the products collection value. For example, etching a 0.1mm-level micropore array on 0.3mm thick glass takes into account both light transmittance and artistic beauty. In addition, laser marking is permanent and can replace traditional ink coding to avoid the risk of falling off or contamination. UV lasers can form high-contrast logos on dark or transparent glass to meet food-grade safety requirements.

 

With the technical characteristics of "zero contact, high precision, and no pollution", UV laser marking machines have redefined the process standards for glass cup decoration and promoted the transformation of traditional manufacturing to digitalization and greening. In the future, with the iteration of technology and the expansion of application scenarios, it will release greater potential in the fields of smart homes, high-end gifts, etc., and become the core driving force for the value upgrade of glass products.
