Laser Welding for Medical Drug Syringe Barrel Seals

Date：2026-04-16 14:42 Source：daokedao Browse：58

Medical drug syringe barrels store drugs for injection, requiring high sealing, moisture resistance, and biocompatibility, ensuring drug stability and no 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 barrel materials, forming a flexible, dense weld, with strong puncture resistance, no cracking during needle 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 syringe welding, production capacity 150 pieces per hour, cycle time 6-8 seconds per unit, helping pharmaceutical manufacturers improve drug packaging quality.
