Advantages of the Post-Bending Screen Printing Process
1. Prevention of Image Distortion and Damage
- In traditional processes, glass softens during heating, causing ink to spread, deform, or crack.
- The post-bending screen printing method eliminates these issues, ensuring precise image placement.
2. Superior Screen Printing Precision
- Since printing occurs after the glass has been fully formed, the position and details remain highly accurate—particularly essential for panoramic sunroofs, HUD glass, and other high-precision applications.
3. Improved Production Yield
- The traditional process risks glass deformation or breakage during bending, leading to high rejection rates for pre-printed glass.
- With post-bending screen printing, only qualified glass is printed, reducing material waste.
4. Greater Design Flexibility
- Enables complex screen printing patterns, such as gradients, fine lines, conductive silver paste, and UV protection coatings, catering to high-end market demands.
5. Wider Ink Selection
- Supports low-temperature curing and UV-curable inks, overcoming the limitations of high-temperature sintering and expanding application possibilities.
l Challenges and Optimization Strategies
Despite its advantages, post-bending screen printing still presents technical challenges:
1. Adaptability to Curved Glass Surfaces
- Post-bending glass may have irregular curvatures, making uniform screen printing difficult.
- Development of curved screen printing platforms with flexible screen meshes and squeegees is required.
2. Ink Adhesion Issues
- Low-temperature or UV-curable inks must undergo rigorous testing to ensure durability, scratch resistance, and chemical stability.
3. Optimization of Post-Printing Curing Processes
- Since high-temperature sintering is not feasible, alternative UV curing, infrared drying, or hot air drying methods are needed.
4. High Equipment Development and Investment Costs
- The industry needs intelligent curved-screen printing machines with automatic alignment systems to enhance printing precision and efficiency.
l Equipment Development Directions
1. Curved-Screen Printing Machine Design
- Adaptation to Glass Curvature: Development of curved-screen printing platforms with adjustable screen frames and curvature-adaptive squeegees.
- Automatic Positioning System: Machine vision + robotic precision alignment ensures high printing accuracy.
- Vacuum Suction Platform: Stabilizes glass and accommodates various curved glass shapes.
2. Low-Temperature Curing Process Development
- UV-Curable Inks: Avoids high-temperature sintering issues while ensuring strong ink adhesion.
- Infrared/Hot Air Drying: Enables rapid ink curing and enhances durability.
3. Highly Efficient Automated Production Lines
- Intelligent Conveyor System: Automates glass transfer, increasing production efficiency.
- Inline Quality Inspection: Incorporates AOI (Automated Optical Inspection) systems to boost yield rates.
4. Customized Screens and Squeegees Optimization
- Optimized Curved Screens: Advanced tension control ensures consistent, uniform printing.
- Flexible Squeegee System: Adapts to glass curvature, preventing uneven prints or ink buildup.
