Daoke Dao Laser Welding for Automotive Door Panel Light Guides: Uniform Light Transmission

Date：2026-01-12 15:49 Source：daokedao Browse：6

Automotive door panel light guides (made of PMMA material) require seamless welding to ensure uniform light transmission. Traditional bonding processes have air bubbles that affect light guiding effect. Daoke Dao plastic laser welding equipment realizes high-quality welding of light guides. The equipment uses a low-heat welding method to avoid material yellowing and ensure high light transmittance of the welds (≥90% of the base material). The precise energy control ensures uniform weld thickness, avoiding light refraction and shadowing. The invisible welds improve the aesthetic effect of the door panel lighting system. Compliant with automotive lighting component standards, the equipment has stable welding performance and high consistency. It supports complex curved light guide welding and can be integrated with automotive interior assembly lines. The quick parameter switching function adapts to different light guide specifications. Daoke Dao helps automotive lighting manufacturers improve the performance of interior lighting systems. Contact us for light transmission test reports.
