Daoke Dao Laser Welding for Automotive Exhaust Gas Sensor Housings: High-Temperature Resistant

Date：2026-01-12 15:53 Source：daokedao Browse：16

Automotive exhaust gas sensors operate in high-temperature exhaust environments, requiring housings with high-temperature resistant welds. Traditional welding methods cannot withstand high temperatures, leading to weld failure. Daoke Dao plastic laser welding equipment provides high-temperature resistant welding solutions. The equipment is suitable for welding high-temperature resistant plastics such as modified PPS and PEI. The welds are fully fused, with thermal stability at 150-200°C, maintaining structural integrity in exhaust environments. The hermetic welding prevents exhaust gas leakage and protects internal sensing elements. Compliant with automotive emission control system standards, the equipment has passed strict high-temperature aging tests. It uses a stable laser source with strong anti-interference ability, adapting to the harsh workshop environment. The automated welding process ensures consistent quality, avoiding the impact of human factors. Daoke Dao helps automotive sensor manufacturers improve product reliability. Contact us for high-temperature aging test reports.
