Plastic Vial Filler Capper

Q: What is a Plastic Vial Filler Capper and its primary application?

A Plastic Vial Filler Capper is an automated aseptic system designed to fill sterile liquids into plastic vials (such as HDPE, LDPE, PP, or PET). It integrates precision filling, rubber stoppering, and capping into a single monoblock unit. It is primarily used for producing ophthalmic drops, injectable solutions, and veterinary products where shatterproof, lightweight plastic is preferred over glass.

Q: How does the machine ensure precision without damaging plastic vials?

To ensure accurate dosing, the machine uses servo-driven piston or peristaltic pumps with a precision of ±0.5% to 1% . For capping, it features torque-controlled capping heads specifically designed for plastic threads. This ensures a leak-proof seal without over-tightening or cracking the flexible plastic neck.

Q: What features prevent product wastage and contamination?

The machine includes several safety and hygiene features: “No Vial – No Filling” system: Sensors prevent dispensing if a vial is not present. “No Vial – No Capping” system: Prevents the machine from wasting caps or stoppers. cGMP Compliance: All contact parts are made of AISI SS 316L , and the framework is AISI SS 304 . It is also designed for integration with Laminar Air Flow (LAF) systems.

Description

Plastic Vial Filler Capper is an automated or semi-automated packaging machine designed for efficiently filling and sealing plastic vials (small containers typically used for liquids, semi-solids, or powders in industries like pharmaceuticals, cosmetics, nutraceuticals, and essential oils). These machines are often compact, monoblock (single-unit) designs that integrate filling, stoppering (if needed), and capping operations to ensure sterility, precision, and high throughput in cleanroom or aseptic environments. They comply with standards like cGMP for safety and hygiene.

Vial Feeding: Dry, sterilized plastic vials are fed through an unscrambler or in-feed turntable and guided onto a moving conveyor belt.

Precise Filling: Vials move under the filling heads where piston or peristaltic pumps dispense predetermined liquid volumes. High-end models often include a “No Vial – No Filling” sensor to prevent spillage.

Stoppering: Immediately after filling, the vials are moved to a station where rubber stoppers are automatically picked and placed using a vibratory bowl system.

Screw or Flip-Off Capping: The stoppered vials then proceed to the capping station. For plastic vials, this often involves a screw-capping head that applies a precise level of torque to secure the cap without damaging the plastic threads.

Final Discharge: Completed vials are transferred to an out-feed conveyor, ready for labeling or secondary packaging.

Working Principle of Plastic Vial Filler Capper

The incoming dry vials (sterilized and siliconized) are fed through the unscrambler and suitably guided on the moving Delrin slat conveyor belt at the required speed of the correct placement below filling unit.

The filling unit consists of Filling Head, Syringes & Nozzles; Syringes & Nozzles are made of AISI SS 316L materials. A Star Wheel is provided which holds the vial during filling operation. A sensor is provided for ”No Vial-No Filling” operation. Syringes are mounted on eccentric block and driving through bottom main gear box. Volume can be increase & decrease by increasing or decreasing stroke length of piston as per filling size. Syringes is having non return valve for sucking and delivering situation to avoid volume variation. Liquid reaches to filling nozzles through silicon transparent pipe. Nozzles having up & down movement with help of cam mechanism, and it come down when vial hold by starwheel for filling operation and starts filling when it starts to move up and after completion of filling operation, starwheel delivers two vials together on conveyor for rubber stoppering operation.

Stoppering unit consist of Star wheel, Vibrator unit and Bowl. The sterilized and siliconized rubber stoppers stored in the vibrator bowl moves vertically to the rubber stopper chute. The vial is hold firmly by starwheel, which will be in continuous rotary motion and vial which is coming from filling unit get in to starwheel and move in rotary direction along with starwheel, during movement it picks up the rubber stopper from the exit end of the chute and rubber stopper pressed by fix single pressing roller, which is spring loaded. Then vial further move on conveyor and collected on out feed starwheel for next sealing operation.

Advantages of Plastic Vial Filler Capper

Integrated "No Vial – No Fill" and "No Vial – No Cap" sensors ensure that expensive liquid formulations and components are only used when a container is correctly positioned.

Built to cGMP standards, these machines feature SS 316L contact parts and are compatible with Laminar Air Flow (LAF) systems, making them ideal for ophthalmic, diagnostic, and injectable products.

These machines use torque-controlled capping heads specifically designed for plastic threads. This ensures a leak-proof seal without over-tightening or cracking the plastic neck.

Most systems are monoblock units, meaning filling, stoppering, and capping occur on a single synchronized base. This reduces the risk of contamination and saves significant cleanroom space.

Key Features of Plastic Vial Filler Capper

Filling Mechanism: Utilizes piston pumps, volumetric syringes, or peristaltic pumps to dispense accurate volumes with precision up to ±1%. Includes sensors for “no vial, no fill” to prevent waste.

Capping System: Automatically places and screws or crimps caps using servo torque control for adjustable tightness, ensuring tamper-evident seals.

Conveyor and Handling: Stainless steel slat belts or turntables feed vials into position; star wheels hold vials steady during processing. Supports ready-to-use (RTU) plastic vials in tubs or nests.

Sterility and Cleaning: Designed for laminar flow protection, with easy-to-clean surfaces, minimal dead zones, and options for pre/post-gassing to maintain product integrity.

Speed and Capacity: Up to 120–600 vials per minute, depending on model; suitable for batch sizes in sterile areas.
