Glass Laser Marking Machine - DISAI

Glass laser drilling is a non-contact manufacturing process that uses a high-energy laser beam to create precise holes in glass without direct mechanical contact. Compared with conventional drilling methods, laser drilling delivers higher accuracy, cleaner hole edges, and reduced risk of chipping or cracking. It is widely used for architectural glass, consumer electronics, automotive glass, medical devices, optical components, and display panels.

Modern laser drilling systems can process a wide range of glass materials, including:

Float glass
Tempered glass (processed before tempering in most cases)
Borosilicate glass
Quartz glass
Soda-lime glass
Ultra-clear glass
Low-E coated glass
Optical glass
Display and touchscreen glass
Material thickness, composition, and coating type may affect drilling parameters and achievable results.

Laser drilling is capable of producing extremely small and highly accurate holes. Typical capabilities include:

Hole diameter: approximately 0.05 mm to 20 mm (depending on equipment and glass thickness)
Positioning accuracy: up to ±0.02 mm
Excellent hole roundness and consistency
Smooth internal walls with minimal post-processing
Custom hole dimensions are available based on project requirements.

In most manufacturing processes, holes are created before the glass is tempered. Drilling fully tempered glass after the tempering process is generally not recommended because it can cause the glass to shatter due to internal stress.
If your application requires holes in tempered glass, our engineering team can recommend the most suitable production process during the design stage.

When the correct laser parameters are used, glass laser drilling produces minimal thermal impact and significantly reduces the likelihood of:

Edge chipping
Micro-cracks
Surface scratches
Mechanical stress damage
Proper material selection and optimized processing parameters help ensure excellent product quality.

Laser-drilled glass is widely used in numerous industries, including:

Consumer electronics
Architectural glazing
Automotive manufacturing
Medical devices
Laboratory equipment
Optical instruments
Solar energy
Home appliances
Industrial automation
The technology is particularly suitable for products requiring complex hole patterns and tight dimensional tolerances.

The process supports a wide range of glass thicknesses, typically from 0.3 mm to 25 mm, depending on glass type, laser power, and hole specifications.
For thicker glass or special applications, customized process development may be recommended.
