Fully Automatic Aluminium Plate Laminating Machine For Soft Board Solar Module

It mainly operates based on the principle of hot-pressing technology. Multiple layers of materials such as laid-out photovoltaic cells, glass, backsheets, and encapsulation films are placed in the working chamber of the laminator.

Through the application of a certain temperature and pressure by the upper and lower heating plates and maintaining it for a specific period of time, the encapsulation film melts and flows under the condition of being heated and pressurized, fully filling the gaps between each layer of materials. Then, after cooling and solidification, each layer of materials is tightly bonded together, and finally a complete and well-sealed photovoltaic module is formed.
