Ophthalmic lens storage housings protect intraocular lenses and contact lenses, requiring high transparency, seamless sealing and sterile performance, preventing lens contamination and scratch damage. Traditional adhesive bonding affects lens transparency, easy residual glue contamination, while ultrasonic welding easily scratches lenses. DaokeDao laser welding is optimized for medical-grade transparent PC and PMMA materials, achieving non-contact seamless welding, no scratch, no residue, preserving lens surface smoothness and transparency. The weld has high sealing performance, blocking dust and moisture, ensuring lens cleanliness and integrity. The process is clean and sterile-grade, complying with ophthalmic medical device production standards, directly entering sterilization packaging after welding. The equipment adapts to miniaturized precision component welding, suitable for ophthalmic device manufacturers, improving product safety and protecting lens quality.
