G+G (Glass to Glass) Vacuum Bonding Machine. Designed for full optical bonding of two glass layers using OCA or SCA adhesive under vacuum pressure. Produces bubble-free, optically clear G+G assemblies for smartphone, tablet, and industrial display refurbishment and manufacturing.
Frequently Asked Questions
What is G+G vacuum bonding and what are its advantages?
G+G (Glass to Glass) vacuum bonding bonds two glass layers — typically a cover glass and a touch panel or LCD glass — using OCA or SCA adhesive under vacuum. This eliminates the air gap, improving display brightness, contrast, sunlight readability, and impact resistance compared to air-gap assemblies.
What adhesive types does this G+G vacuum bonding machine support?
This machine supports both OCA (Optically Clear Adhesive) film and SCA (Super Clear Adhesive) liquid glue for G+G bonding, providing flexibility for different production requirements and glass types.
How does this G+G bonding machine differ from the CG+OCA vacuum laminating machine?
The G+G vacuum bonding machine is optimized specifically for glass-to-glass bonding with enhanced vacuum and pressure control for rigid substrates. The CG+OCA model focuses on cover glass and OCA film lamination workflows. Both support OCA adhesive but are calibrated for different bonding structures.
What glass sizes can this G+G vacuum bonding machine process?
Please contact our technical team for the specific working area dimensions and maximum glass panel size supported by this model, as specifications vary by configuration.
