Daoke Dao Laser Welding for Automotive Fuel Level Sensor Plastic Housings: Leak-Proof & Corrosion-Resistant
Automotive fuel level sensors are installed in fuel tanks, and their plastic housings require leak-proof and corrosion-resistant welding to ensure accurate fuel level measurement and long-term operation in fuel environments. Traditional welding has poor sealing and is prone to corrosion by fuel, leading to fuel leakage and sensor failure. Daoke Dao plastic laser welding equipment solves these problems.
The hermetic weld seam of the plastic housing achieves a helium leak rate ≤1×10⁻⁸ mbar·L/s, effectively preventing fuel leakage. Suitable for HDPE and PP plastic materials resistant to fuel corrosion, the welds maintain integrity in gasoline and diesel environments, avoiding corrosion and aging. The low-heat process avoids plastic deformation, ensuring the sensor’s measurement accuracy.
Compliant with IATF 16949 and automotive fuel system standards, it integrates into automated fuel tank assembly lines with a welding speed of 2 sensors per second. The equipment supports customized plastic housing shapes, adapting to different fuel tank designs. Daoke Dao helps automotive sensor manufacturers improve product reliability.
