Liquid-applied damping (LASD) and robotic application in the automotive industry
Liquid Applied Sound Deadener (LASD) is a sound-damping product based on water-based coating. Robotic application lets it be placed precisely at each vibration point.
What LASD is
LASD dissipates vibration energy and converts structure-borne noise into heat, which lowers cabin noise and raises ride comfort.
Why a robot applies it
Different models have different structures and designs, and their vibration points lie in different places, so the application method must be flexible and precise. Locate each vibration point by simulation and real-vehicle testing, then let a robot spray precisely at those points: dosing is exact, the coating is spread evenly in the cabin, repeatability and stability are high, and material waste is reduced.
What it does for the line
Robot application is flexible: when the model changes, the preset programme can be edited quickly to meet the new spraying requirements, which helps build a flexible production line, cuts material waste in changeovers and raises efficiency.
