Daoke Dao Laser Welding for Automotive ECU Plastic Housings: Shielded & Waterproof
The Engine Control Unit (ECU) is the core of automotive electronics, and its plastic housing requires strict shielding and waterproof performance to resist harsh engine bay environments. Traditional welding methods such as ultrasonic welding leave gaps and poor electromagnetic shielding, leading to signal interference and ECU failure. Daoke Dao plastic laser welding equipment solves these pain points perfectly.
Suitable for PC/ABS and conductive plastic composites, the welds achieve electromagnetic shielding effectiveness ≥42dB, effectively blocking external signal interference and protecting internal chips and circuits. The hermetic weld seam meets IP67 waterproof and dust-proof standards, preventing moisture, dust, and engine oil intrusion. With ±0.02mm positioning accuracy, it ensures precise alignment of housing upper and lower covers, avoiding damage to internal components.
Compliant with IATF 16949 and automotive electronic standards, the equipment integrates seamlessly into automated production lines with a welding speed of 1.2m/min. The low-heat welding process avoids plastic deformation and surface discoloration, maintaining the housing’s structural integrity and aesthetic appearance.
