Prefilled syringe equipment refers to the specialised machinery used for producing prefilled syringes, covering the core processes of filling, sealing, and inspection. It is a key piece of production equipment in the pharmaceutical and medical device fields.
I. Main Types
Glass ampoule filling and sealing machines – Designed specifically for glass prefilled syringes. They feature synchronised high‑precision filling and sealing to ensure accurate dosage and reliable seal integrity.
Plastic syringe assembly machines – Designed for plastic syringes, these can efficiently assemble components such as the barrel, plunger rod, and piston, making them suitable for large‑scale production.
II. Working Process
Washing – The syringe barrels are cleaned and sterilised to ensure internal sterility and prevent drug contamination.
Filling – The precise dose of drug solution is injected according to preset parameters, with volumetric error controlled at the microlitre level.
Sealing – The syringe is sealed using either melt‑sealing or rubber‑stopper compression techniques to prevent leakage.
Inspection – Checks are performed via weighing, visual inspection, or automated systems to detect defects such as dosage deviation or poor sealing.
III. Application Areas
Pharmaceutical industry – Widely used in the production of vaccines, biologics, and other injectable products, meeting the stringent requirements for sterility and stability.
Medical institutions – Used for dispensing specialised medications such as anaesthetics and chemotherapeutic agents, thereby improving clinical medication safety.
