1. Vial Loading

• Clean and sterilized empty vials are loaded onto the infeed conveyor or vial feeding system.
• The machine automatically transfers the vials for continuous processing.

2. Vial Feeding & Indexing

Vials are guided and positioned accurately using an indexing mechanism to ensure synchronized movement during filling and stoppering operations.

Sensors monitor:

• Vial presence
• Correct positioning
• Smooth conveyor movement

3. Filling Operation

The liquid product is filled into the micro vials using:

• Peristaltic pump
• Piston pump
• Servo-controlled filling system

depending on product characteristics and required filling accuracy.

Filling Features

• High-precision micro-volume filling
• Adjustable filling volume
• No vial – No filling system
• Drip-free filling nozzles
• Minimal product wastage

4. Stopper Feeding

Rubber stoppers are automatically fed through a vibrator bowl or feeder arrangement and transferred to the stoppering station.

5. Stoppering Operation

The machine automatically places and presses rubber stoppers onto the filled vials to ensure secure and contamination-free sealing.

6. Optional Weight Checking System

An inline check-weighing system can verify:

• Correct fill volume
• Underfilled vials
• Overfilled vials

Non-conforming vials are automatically rejected from the production line.

7. SCADA Monitoring (Optional)

Integrated SCADA software provides:

• Real-time process monitoring
• Batch data recording
• Alarm management
• Production reporting
• User access control and traceability

8. Vial Discharge

Filled and stoppered vials are discharged through the outfeed conveyor for:

• Capping
• Inspection
• Labeling
