Medical drug capsule shell seals protect internal powder or granular drugs, requiring high sealing, moisture resistance and biocompatibility, ensuring drug stability during shelf life, no moisture intrusion and drug leakage. Traditional mechanical pressing has gaps, easy moisture entry, leading to drug damp failure. DaokeDao laser welding adopts a low-heat precise process, suitable for medical-grade gelatin and plant capsule materials, forming a seamless and dense seal, completely isolating moisture and air, ensuring drug stability and efficacy. The weld is smooth and burr-free, no damage to capsule appearance, suitable for automatic filling production lines. The process is particle-free and residue-free, no drug contamination, complying with pharmaceutical packaging safety standards. The equipment supports high-speed capsule sealing production, with high consistency, helping pharmaceutical manufacturers improve drug packaging quality and extend drug shelf life.
