With extremely high precision, the BENTELER Edge Sealing System creates a seam made of butyl hotmelt. Depending on the preferred EVA or PVB laminating foil, the sealing seam is exactly formed and laid down on the solar module. The machine design places maximum value on process reliability. Laser-based sensors permanently monitor the sealing seam. A massive centering table ensures the necessary firm hold of the glass for uniform quality. The robust design and the simple operation permit global use.

Advantages

Use of more cost efficiency laminating foil: 

• Increase in competitiveness

Improved protection of the module against moisture: 

• Longer product warranties possible

Extremely high working speed:

• Improvement of the cycle time

MES linkage: 

• Simple integration into modern control systems

Maximum process reliability: 

• Less faulty parts, less warranty cases

Modular design: 

• Easy integration in existing production lines

BENTELER offers various plant conceptions for so-called "railbonding". No matter whether a simple "tape“ based adhesive technology is desired, or a 1K or 2K adhesive or a combination of tape and adhesives is required, BENTELER has an appropriate solution for its customers. We combine these with practically every kind of available rails. Our portfolio also includes integrated equipment for pretreatment of the rails by means of cleaner and primer. The end result is that the customer receives a modularly designed, individual machine for 24/7 continuous operation according to the requirements of modern solar module production.

Advantages

Completion of the "solar module product" with an appropriate assembly system

• Added value for the final customer
• Reduction of glass break risk due to stress and fatigue

Practically any process combination rail/adhesives/glass is possible 

• Individualization according to customer wishes

MES linkage: 

• Simple integration into a modern control system

Process reliability: 

• Less faulty parts, less warranty cases

Modular design:

• Simple integration in existing production lines
