Laser Welding for Automotive Fuel Tank Ventilation Valves

Date：2026-04-01 14:22 Source：daokedao Browse：29

Automotive fuel tank ventilation valves regulate the air pressure inside the fuel tank, prevent fuel volatilization and emissions, and are key components for vehicle emission compliance, requiring good air tightness, chemical resistance and reliable operation. Traditional assembly methods have poor air tightness, easy fuel gas leakage, failing to meet EU and US emission standards. DaokeDao plastic laser welding is suitable for fuel-resistant PP and PA materials, forming a high-density airtight weld, with air leakage rate controlled below 0.01m³/h, fully meeting vehicle emission regulations. The weld has excellent chemical resistance, withstands long-term fuel and oil erosion without corrosion and failure, adapting to a temperature range of -40°C to 120°C. The welding process has high precision, does not affect the internal valve structure, ensuring normal opening and closing of the valve. The equipment has online air tightness detection function, automatically screening unqualified products, ensuring each product meets standards, helping automakers meet strict emission regulations and reduce environmental pollution.
