A method for manufacturing a glass panel unit includes an adhesive disposing step, a glass composite generation step, an internal space forming step, an evacuation step, and an evacuated space forming step. The adhesive disposing step includes disposing a thermal adhesive on a second panel. The glass composite generation step includes generating a glass composite including a first panel, the second panel, and the thermal adhesive. The internal space forming step includes heating the glass composite to melt the thermal adhesive to form internal spaces (a first space and a second space). The evacuation step includes exhausting gas from the internal space to evacuate the internal space. The evacuated space forming step includes heating and applying force to part of a first portion or a second portion to deform the part to close an evacuation path to form an evacuated space hermetically closed.

A glass panel unit manufacturing method includes a bonding step, an insertion step, an evacuation step, and a sealing step. The bonding step includes bonding a first substrate having an evacuation port and a second substrate together with a bonding material provided between the first substrate and the second substrate and having a frame shape to form an internal space. The insertion step includes inserting a sealing material into the evacuation port. The evacuation step includes evacuating the internal space through the exhaust passage. The sealing step includes deforming the sealing material by heating while an evacuated state in the internal space is maintained. In a state where the sealing material blocks ventilation between the evacuation port and the internal space, gas is supplied through the exhaust passage toward the evacuation port.

Methods for manufacturing insulating glass units (IGUs) include providing an unsealed IGU assembly that has first and second sheets of glass material and at least one spacer frame between the first and second sheets and sealed to at least one of the first and second sheets. The unsealed IGU assembly defines an interpane space and an IGU passage providing fluid communication between the interpane space and an environment external to the interpane space. In some cases the method includes positioning a filling device next to the IGU passage and introducing a gas into the interpane space through the IGU passage using the filling device. In some cases the method includes delivering a sealing material or sealing structure to the IGU passage with the filling device to seal the interpane space. Corresponding systems for manufacturing IGUs are also provided.
