"Engineered for highly viscous and bubble-sensitive aesthetic products-including cross-linked Hyaluronic Acid (HA), recombinant collagen, mesotherapy cocktails, and microsphere suspension gels-we provide fully flexible, scratch-free, and anti-tailing aseptic filling solutions tailored exclusively for Prefilled Syringes (PFS)."
Industry challenges and pain points
Medical Aesthetics Precision Filling Solutions
Extreme High Viscosity & Tail-Dripping: Aesthetic gel formulations possess exceptionally high viscosity. When the filling nozzle retracts from the syringe, it is highly prone to trailing and dripping, which severely compromises the syringe's sealing surface and triggers critical sterility and aesthetic non-compliance.
Entrapped Air Bubbles During Vacuum Stoppering: If micro-bubbles become entrapped within the dense gel during plunger insertion, it not only creates visual defects that trigger product rejects, but can also cause fluid leakage, needle dislodgement, or inaccurate dosing during clinical injection by practitioners.
Ultra-Strict Aesthetics Protection for Packaging: Aesthetic brand owners enforce uncompromising visual standards for plastic prefilled syringe barrels. Any microscopic scratches induced by rigid mechanical friction during automated transport will significantly degrade the product's premium brand image.
product key technologies
Servo-Driven Filling
The filling nozzles are driven by advanced servo motors to submerge into the bottom of the syringe, retracting synchronously with the rising fluid level. Paired with a precision nozzle suck-back valve design, it completely eliminates trailing, tail-dripping, and surface bubbles associated with highly viscous formulations.
Multi-Stage Vacuum Stoppering Process
Utilizes advanced negative-pressure venturi tubes or mechanical plunger insertion coordinated with multi-stage deep vacuum profiles. This engineering matrix guarantees 100% visible bubble-free interfaces between the highly viscous gel and the elastomer plunger.
Prefilled Syringe (PFS) Vacuum Filling & Stoppering Machine
The entire machine features comprehensive servo control and patented technology to guarantee 100% bubble-free processing. It can operate as a high-efficiency standalone unit or be seamlessly integrated with our downstream/upstream equipment to achieve a fully automated, turnkey production line-encompassing automated de-nesting, syringe feeding, optical inspection, and fully automated plunger rod insertion and labeling.
We can recommend optimal configurations based on your actual manufacturing requirements, delivering a tailormade, fully customized solution.
Prefilled syringe vacuum filling and stoppering machine is a vacuum filling and stoppering machine developed by our company specifically for laboratory-type and small-batch prefilled syringes. It adopts full servo control and vacuum filling and stoppering. It has the advantages of small footprint, high filling accuracy, no bubble generation, etc. It is also easy to clean, operate and maintain.
The system is designed for the automatic filling and stoppering of RTU nest plate/box type prefilled syringes. It can complete a series of actions including unpacking, heating and tearing film, removing liner, filling, stoppering, adding rods and labeling, which reduces the involvement of personnel, greatly improves production efficiency, and also reduces the risk of contamination. It is compatible with the filling of cartridges, vials, etc., and is sterile throughout the process.
Seamless Integration with Downstream Packaging: Plunger Rod Insertion & Labeling
To provide a truly comprehensive turnkey solution, our high-speed filling line seamlessly integrates with our advanced Automatic Syringe Plunger Rod Insertion and Labeling Machine.
Once the nested syringes are vacuum-filled and stoppered, this fully automated downstream system takes over with uncompromised precision. It precisely executes plunger rod screwing, missing-rod detection, and high-speed wrap-around labeling in a single, continuous workflow. By minimizing human intervention and product handling, this integration guarantees maximized Overall Equipment Effectiveness (OEE) and absolute traceabilty for your commercial production.
