Daoke Dao Laser Welding for Automotive Engine Coolant Temperature Sensor Plastic Housings: High-Temperature & Corrosion-Resistant
Date:2026-02-25 15:04     Source:daokedao     Browse:31
Automotive engine coolant temperature sensors use plastic housings, which require high-temperature and corrosion-resistant welding to ensure accurate measurement in high-temperature coolant environments. Traditional welding has poor heat resistance and is prone to corrosion by coolant, leading to sensor failure and engine overheating. Daoke Dao plastic laser welding equipment provides reliable solutions. Suitable for heat-resistant and corrosion-resistant plastic materials such as PPS and modified PP, the welds can withstand operating temperatures up to 125°C and resist coolant corrosion, maintaining structural integrity for long-term use. The hermetic weld seam prevents coolant intrusion, protecting internal sensing elements and ensuring measurement accuracy (±0.4°C). Compliant with IATF 16949 and automotive engine system standards, it integrates into automated sensor production lines with a welding speed of 2 sensors per second. The ±0.01mm positioning accuracy ensures precise assembly. Daoke Dao helps automotive sensor manufacturers improve product reliability in harsh engine environments.
