Automatic Vial Sticker Labeling Machine
Precision Quality Assurance for Injectables
The Harsiddh Automatic Vial Sticker Labeling Machine (HVSL Series) is an essential solution for the pharmaceutical, biotech, and cosmetic industries. Designed for 24/7 industrial operation, it features a rugged linear design that integrates easily into existing production lines. The machine’s advanced feedback control and stepper/servo motor drive ensure that even transparent “no-look” labels are applied with high-resolution accuracy and professional finish.
Reliable Operational Workflow
The machine provides a continuous, automated workflow to maximize efficiency:
- Feeding: Vials are transferred from the previous station or a Turn Table onto the conveyor in a vertical position.
- Indexing & Sensing: A spacing device (worm or star-wheel) creates uniform gaps between vials, while an optical sensor triggers the label dispenser.
- Dispensing: The servo-driven applicator releases the self-adhesive label precisely as the vial passes the labeling head.
- Wrap-Around Pressing: A synchronized belt or foam roller rotates the vial against the label to ensure bubble-free adhesion and perfect overlap.
- Inspection & Discharge: Inspected units continue to the collection tray; optional vision systems can verify barcodes and batch codes before discharge.

Frequently Asked Questions
How does the machine ensure the label is applied straight on such a small surface?
Precision is achieved through a Three-Point Stabilization System. As the vial enters the labeling zone:
Top Pressing Device: A motorized belt or plate stabilizes the vial from above.
Wrap-Around Belt: A high-speed foam-lined belt rotates the vial at a synchronized speed with the label dispenser.
Accuracy: This setup ensures the label wraps perfectly around the circumference with a placement accuracy of ±0.5mm to ±1mm, preventing wrinkles or "flagging."
Can the machine handle different label materials, such as transparent or metallic stickers?
Yes. The machine is compatible with various self-adhesive label materials. For standard paper or metallic labels, it uses a high-speed photoelectric sensor. For transparent "no-look" labels, the machine can be fitted with an optional ultrasonic sensor that detects the thickness of the label rather than its opacity, ensuring consistent dispensing every time.
How does the machine comply with "Track and Trace" pharmaceutical regulations?
To meet stringent cGMP and regulatory standards, the Harsiddh Vial Labeler can be integrated with:
Online Coding: Integration with Thermal Inkjet (TIJ) or Laser Coders to print Batch Numbers, Exp. Dates, and 2D DataMatrix codes.
Vision Inspection: An optional high-speed camera system to verify label presence and barcode legibility.
Auto-Rejection: A pneumatic "Reject" arm that removes any vial with a missing or unreadable label into a secure bin without stopping the production line.
What is the production capacity and how are changeovers managed?
The machine is built for high-efficiency manufacturing:
Output: Depending on the vial diameter and label length, the machine can process 120 to 300 vials per minute.
Changeovers: It features a "No-Tool" adjustment design. By using calibrated handwheels and swapping out the star-wheel (if applicable), operators can switch between different vial sizes (e.g., 5ml to 15ml) in less than 15 minutes.
