Daoke Dao Laser Welding for Automotive Door Panel Speaker Grilles: Aesthetic & Acoustic-Friendly

Date：2026-01-19 14:00 Source：daokedao Browse：5

Automotive door panel speaker grilles need seamless welding to balance aesthetics and acoustic performance. Traditional grilles have visible welds and poor sound transmittance. Daoke Dao plastic laser welding equipment achieves optimal grille quality. Invisible welding creates a smooth surface, integrating with the door panel interior. The welds maintain the grille’s mesh structure, ensuring sound transmittance ≥90%. Compatible with ABS and PC materials, it avoids material deformation that distorts sound. Compliant with automotive interior standards, the equipment supports complex grille patterns and curved designs. It integrates into automated door panel assembly lines, with a welding cycle of 8 seconds per unit. The low-heat process preserves the grille’s surface texture and color. Daoke Dao helps auto audio and interior manufacturers. Contact us for acoustic test reports.
