Laser Welding for Medical Drug Vial Cap Seals

Date：2026-04-15 13:49 Source：daokedao Browse：4

Medical drug vial cap seals ensure drug sterility and stability, requiring high sealing, moisture resistance, and puncture resistance, adapting to clinical injection puncture, no drug leakage and contamination. Traditional rubber stoppers have poor sealing, easy moisture entry, leading to drug degradation, while mechanical capping has gaps. DaokeDao laser welding adopts a low-heat precise process, suitable for medical-grade rubber and PP cap materials, forming a flexible, dense weld, with strong puncture resistance, no cracking during puncture. The weld has high sealing performance, blocking moisture and air, ensuring drug stability during shelf life. The process is clean and residue-free, complying with pharmaceutical packaging standards. The equipment supports high-speed vial capping welding, production capacity 140 pieces per hour, cycle time 6-8 seconds per unit, helping pharmaceutical manufacturers improve drug packaging quality.
