Dental instruments—such as handpieces, orthodontic brackets, and dental impression trays—require hygiene, durability, and resistance to repeated sterilization. These instruments are used in oral procedures, where they come into contact with saliva, blood, and dental materials, making cleanliness and sterilization resistance critical. Traditional welding methods may leave gaps or rough surfaces that harbor bacteria, or produce welds that degrade under autoclave sterilization. DaokeDao plastic laser welding creates sealed, easy-to-disinfect surfaces that prevent bacterial contamination. The hermetic welds are resistant to autoclave sterilization (high temperature and pressure) and chemical disinfectants, ensuring long-term durability. The non-contact process generates no particles or contaminants, ensuring the cleanliness of dental instruments. It forms high-strength welds that withstand the mechanical stress of dental procedures. The process is compatible with medical-grade plastics used in dental instruments, including PC, ABS, and PPS, which are biocompatible and resistant to dental materials. Our laser systems support small, precision components, adapting to the compact design of dental instruments. They help dental instrument manufacturers improve product hygiene, durability, and patient safety.
