Automotive suspension sensors monitor vehicle suspension movement, providing critical data to ADAS and stability control systems. These sensors operate in a harsh environment—exposed to vibration (10-1500Hz), road debris, moisture, and temperature changes (-40°C to 85°C). They require high precision (measurement accuracy ≤±0.1mm), anti-vibration performance, and structural stability to ensure accurate signal output. Traditional welding methods may introduce vibration that misaligns internal sensor components, or cause thermal deformation that affects measurement accuracy. DaokeDao laser welding protects internal sensor structures by using a vibration-free, low-thermal-impact process. It ensures precise alignment of internal components (tolerance ≤±0.008mm), maintaining accurate signal output for suspension control systems. The welds are strong and resistant to vibration and impact (shear strength ≥24MPa), ensuring that the sensor remains stable even under extreme road conditions. The hermetic seal created by laser welding meets IP66 standards, blocking moisture and dust intrusion. Our laser systems feature micron-level positioning accuracy, ensuring that the weld joint does not interfere with sensor performance. They support small, compact sensor designs, adapting to the limited space in suspension systems. By improving the precision and reliability of suspension sensors, DaokeDao laser welding helps automakers enhance vehicle control, comfort, and safety.
