Currently, colored coated glass is increasingly widely used in fields such as architectural decoration, artistic design, smart homes, and optical instruments. In particular, "double-sided coated red glass" is highly favored by high-end project clients due to its vibrant colors, strong visual impact, and excellent optical performance. However, high-value-added double-sided coated glass imposes extremely high requirements on processing precision, edge quality, and thermal damage control, making traditional mechanical processing methods prone to defects such as cracking, burrs, and surface coating detachment.
Customer requirements:
The laser cutting of "double-sided coated red glass" for this project is primarily used in high-end decorative glass applications. The client explicitly specified the following processing requirements: precise cutting dimensions, high batch consistency, no edge chipping or microcracks, intact coating layers, and no peeling or discoloration. However, in actual processing, double-sided coated glass is highly sensitive to heat input, and minor deviations during cutting may lead to issues such as edge whitening, coating blistering, or even complete glass fracture, making the processing particularly challenging.
Solution:
The "Infrared Picosecond Laser Glass Cutting Machine" from ChuangkeDa features a high-energy-density picosecond laser source, an intelligent visual positioning system, and a high-precision motion platform, enabling non-contact, low-thermal-impact, and burr-free cutting. During the cutting process, laser energy is uniformly applied to the interior of the glass, creating clean cross-sections through the cold cracking principle. The entire cutting edge can be directly assembled and used without secondary polishing. For complex irregular paths, the machine's intelligent control system can accurately operate according to CAD drawings, ensuring every arc and angle perfectly matches the design. The machine boasts a cutting precision of up to ±0.01mm, with excellent verticality and burr dimensions ≤5μm. It supports arbitrary graphic cutting, allowing circular, square, curved, or irregular profiles to be completed in a single operation. Additionally, the integrated automated processing platform enables simultaneous cutting of multiple glass pieces, significantly enhancing production efficiency and providing high-quality, high-efficiency solutions for precision glass processing.
Laser cutting effect:
• Processing material: "Double-sided coated red glass"
• Cutting precision: ±0.01 mm
• Edge break control: ≤5 μm
• Processing Effect: The edges of the cut samples are smooth and flat, with no chipping or microcracks, and the coating surface exhibits uniform and complete coloration. Upon customer inspection, the dimensional accuracy of the cuts fully meets the design requirements, allowing the edges to proceed directly to the subsequent assembly stage without the need for secondary polishing.
• Processing Advantage: Supports circular, square, and various irregular glass cutting. R-edges, ellipses, and complex profiles can be high-precision repeated processing, ensuring stable mass production and strong dimensional consistency.
