Injectable Vial Filling & Stoppering Machine by N.K. Industries
N.K. Industries is a leading manufacturer, exporter, and supplier of a wide range of Injectable Vial Filling & Stoppering Machines, designed to meet the diverse needs of the pharmaceutical industry. These automatic machines are ideal for filling liquid into vials and simultaneously applying rubber stoppers, making them a crucial part of the complex injectable unit in pharmaceutical companies.
Our range of machines is available in 2-head, 4-head, 6-head, 8-head, and 12-head configurations, offering production speeds from 50 vials per minute to 200 vials per minute, depending on the fill volume. A standout feature of this machine is the innovative “No Vial - No Fill” system and “No Vial – No Stopper” system, ensuring high efficiency and minimal waste. The machine can also be customized with optional accessories like Laminar Air Flow, Toughened Glass Safety Cabinet, and Pre-Post Nitrogen Flushing Units for enhanced performance.
How Does the Injectable Vial Filling & Stoppering Machine Work?
The working process of the Injectable Vial Filling & Stoppering Machine is precise and reliable. Here’s a step-by-step overview:
-
Feeding Vials: Sterilized dry vials are fed via an unscrambler onto a AISI 304 Made Slat Conveyor Belt at a controlled speed, ensuring correct placement under the filling unit.
-
Filling Process: The filling unit consists of syringes and nozzles. The syringes, available in stainless steel 316 (SS316) or glass (customer’s choice), are driven by a gear system. The fill volume can be adjusted by modifying the stroke length of the piston. A Star Wheel holds the vials during the filling process, while a sensor ensures “No Vial - No Fill” operation.
-
Liquid Transfer: Liquid is transferred through a silicon transparent pipe, with the nozzle moving up and down, controlled by a cam mechanism. Once the vial is positioned, the filling begins, and after completion, the star wheel moves the vials to the stoppering unit.
-
Stoppering Process: The sterilized rubber stoppers are fed via a Vibrator Bowl to the chute. As the star wheel moves the vials, the stopper is automatically picked up and pressed onto the vial by a spring-loaded pressing roller. The vials then move to the conveyor for the next sealing operation.
