Vibration-Free Laser Welding for Medical Hearing Aid Components

Date：2026-03-20 14:47 Source：daokedao Browse：13

Hearing aids are small, precision devices that require miniaturized components, biocompatibility, and reliable performance. These components (such as battery housings and sound channels) are made of medical-grade plastics like PC and acrylic, demanding a vibration-free welding process to protect sensitive internal electronics. Traditional ultrasonic welding introduces vibration that damages microphones and speakers, leading to sound distortion. DaokeDao laser welding is vibration-free and low-thermal-impact, protecting internal electronics from damage. The laser focuses on the weld joint with ultra-precise positioning (±0.003mm), creating a seamless, hermetic seal (IP67 rating) that blocks moisture and dust. It forms a biocompatible bond (ISO 10993) that is safe for skin contact. Our systems support miniaturized component designs (size ≤15mm×10mm×5mm) and high-volume production (up to 120 units/hour). By improving hearing aid reliability and sound quality, DaokeDao laser welding helps medical device manufacturers enhance patient quality of life.
