Automated Tile Flatness Inspection Using Laser Displacement Sensors
In tile manufacturing, flatness directly affects installation quality and visual appearance. Even small bends or surface unevenness can lead to rejection after delivery. Manufacturers need a stable inspection method that works at production speed, avoids surface damage, and delivers consistent results for quality control.
