Daoke Dao Laser Welding for Automotive Sunroof Drainage Pipes: Leak-Proof & Corrosion-Resistant

Date：2026-01-19 14:24 Source：daokedao Browse：7

Automotive sunroof drainage pipes require leak-proof welding to avoid water intrusion into the cabin. Traditional pipes easily leak at joints, causing interior damage and mold growth. Daoke Dao plastic laser welding equipment ensures drainage pipe integrity. Suitable for PP and HDPE materials, the welds form a continuous seal with a water leakage rate of 0ml/min under 0.5MPa pressure. The welds resist rainwater and cleaning agents, maintaining long-term durability. The flexible welding path adapts to the pipe’s curved layout. Compliant with automotive body standards, the equipment integrates into automated sunroof assembly lines, with a welding speed of 1.5m/min. It supports pipes of different diameters (8-15mm), with quick fixture switching. The stable weld quality ensures consistent performance across batches. Daoke Dao helps auto body manufacturers.
