Daoke Dao Laser Welding for Automotive Radar Sensor Plastic Casings: Shielded & Weather-Proof
Automotive radar sensors (such as adaptive cruise radar) use plastic casings, which require shielding and weather-proof welding to ensure signal stability and long-term operation in outdoor environments. Traditional welding has poor shielding performance and is prone to aging under UV radiation, leading to radar signal distortion and failure. Daoke Dao plastic laser welding equipment optimizes the manufacturing of radar plastic casings.
Suitable for PC/ABS plastic composites with conductive fillers, the welds achieve electromagnetic shielding effectiveness ≥45dB, ensuring that radar signals are not interfered with by external electronics. The hermetic weld seam resists UV radiation, rainwater, and temperature changes (-30°C to 80°C), adapting to harsh outdoor environments. The low-heat process avoids plastic aging and yellowing, maintaining the casing’s performance.
Compliant with automotive electronic and IATF 16949 standards, it supports 3D curved plastic casing welding with a welding speed of 1m/min. The equipment can store multiple sets of parameters, adapting to different radar sensor models. Daoke Dao helps automotive radar manufacturers improve product stability.
