Clinical thermometer probe housings protect internal temperature sensing elements, requiring high sensitivity, sealing and biocompatibility, ensuring accurate temperature measurement, no irritation to human mucosa. Traditional assembly processes have poor sealing, easy entry of moisture and debris, affecting measurement accuracy. DaokeDao laser welding adopts a low-heat non-contact process, suitable for medical-grade PC and ABS materials, forming a seamless and smooth weld, blocking moisture and debris intrusion, protecting internal sensing elements, ensuring temperature measurement accuracy (error ≤±0.1°C). The weld has no sharp edges, no irritation to oral or axillary mucosa, safe for clinical use. The process is clean and particle-free, complying with medical device production standards. The equipment supports miniaturized probe welding, with high consistency, suitable for mass production of thermometer manufacturers, improving product accuracy and safety.
