Fully Automatic Vacuum Insulated Glass Production Line
From loading tempered glass to the vacuum sealing furnace, one line handles washing, measuring, pillar placement, frit dispensing, drying, glass pairing and clipping. Glass moves between stations automatically, and the whole line needs only 5 operators.
