Surgical suture needle storage housings protect disposable suture needles, requiring firm sealing, sterile and non-toxic, preventing needle contamination and accidental injuries. Traditional mechanical packaging has loose fit, easy housing opening, leading to needle contamination. DaokeDao laser welding realizes seamless and firm sealing of storage housings, suitable for medical-grade PP materials, with high weld strength, not easy to open, effectively protecting suture needles from contamination and avoiding accidental injuries. The entire welding process is completed in a clean environment, zero particle generation, complying with medical device sterile production standards, directly entering ethylene oxide sterilization after welding. The equipment supports high-speed production, with single-piece cycle time 3-5 seconds, production capacity 200 pieces per hour, fully meeting the large-demand supply of surgical consumables. It helps surgical consumable manufacturers improve product safety and reduce medical safety risks.
