Robust cutting technology for flexible thin glass (< 100 µm) and thin glass-polymer laminates with elevated edge quality (smooth, no chipping, good edge strength) to obtain bendable elements.
Details of the Technology Call
Glass rolls with about 20 m length and a thickness of 50 -100 µm are laminated with an adhesive tape. These thin glass-adhesive tape laminates are used to build glass-glass-encapsulated OLEDs in a roll-to-roll process. The next step for commercialization is to separate the roll into single functional elements. The combination of thin glass film and adhesive tape would deliver a perfect whole-in-one solution for the encapsulation of water sensitive organic materials.
To keep the bendability, the cutting process has to be very accurate and the resulting glass edge free of defects.
A proposed solution should have the following properties:
- 1-pass inline Roll-to-roll integration possible
- Cutting speed > 5 m/min
- Circular scissions with radii ≥ 1 mm
- Cutting of several glass qualities (starting point: alkali containing and –free borosilicate glass)
- Resulting quality
- Edge strength > 150 MPa
- Target bending radius
- No deformation, melting burrs or other thermal side effects
- No chipping
Nice to have:
- Simultaneous cutting of glass and polymer
Possible solution areas
- Glass shaping
- Glass forming
- Apparell industry
- Jewelry industry
- Shape cutting industry
A combination of above possible solutions or other technologies is interesting.
