Daoke Dao Laser Welding for Automotive Transmission Control Unit (TCU) Plastic Housings: Heat-Resistant & Durable

Date：2026-02-25 15:01 Source：daokedao Browse：4

Automotive TCU plastic housings require heat-resistant and durable welding to withstand high temperatures in the engine bay and ensure stable transmission control. Traditional welding deforms plastic under heat and has weak welds, leading to TCU failure and transmission malfunctions. Daoke Dao plastic laser welding equipment optimizes the manufacturing process. Suitable for heat-resistant plastic materials such as PPS and PA66, the welds can withstand operating temperatures up to 135°C, resisting heat generated by the transmission and engine. The welds have high tensile strength (≥32MPa), ensuring the housing can withstand long-term vehicle vibration and mechanical stress. The hermetic weld seam prevents engine oil and coolant intrusion, protecting internal circuits. Compliant with IATF 16949 and automotive transmission system standards, it integrates into automated TCU production lines with a welding speed of 1.2m/min. The precise energy control avoids plastic brittleness, ensuring long-term durability. Daoke Dao helps automotive transmission manufacturers improve TCU stability.
