Automatic Four Head Vial Cap Sealing Machine
High-Speed Capping for Sterile Lines
The Harsiddh Automatic Four Head Vial Cap Sealing Machine (HVCS-120) is engineered for high-volume pharmaceutical packaging. By utilizing a four-head rotary configuration, it offers a substantial increase in output compared to single-head models while maintaining a compact footprint. The machine is designed specifically for aluminum and flip-off cap applications, ensuring that every vial is hermetically sealed with clinical precision.
Reliable Operational Workflow
The machine provides a continuous, high-speed path from stoppered vial to sealed container.
Sequence of Operation:
- Bottle In-feed: Stoppered vials are indexed from the conveyor into the star wheel.
- Cap Delivery: Caps are oriented in a vibratory bowl and delivered via a chute; sensors verify the presence of both the cap and the stoppered vial.
- Rotary Sealing: As the turret rotates, the four sealing heads descend. The spring-loaded rollers tuck the aluminum skirt under the vial rim.
- Safety Check: If a jam occurs, the safety clutch disengages the drive immediately to prevent vial breakage.
- Discharge: Sealed vials are smoothly transitioned to the exit conveyor for downstream labeling.

Frequently Asked Questions
How does the "Rotary Spinning" sealing mechanism work?
Unlike simple vertical pressing, our machine uses a Spinning Roller Sealing method. As the vial is lifted into the sealing head, three or four rollers rotate around the neck of the vial, gradually folding the aluminum cap skirt under the vial’s rim. This ensures a uniform, 360-degree seal that is significantly more reliable and aesthetically cleaner than traditional crimping.
What is the production capacity of this Four Head model?
The Four Head Vial Sealer is built for efficiency, typically achieving an output of 70 to 100 vials per minute. This makes it the ideal "mid-range" choice for pharmaceutical labs and manufacturers who have outgrown single-head machines but do not yet require the 200+ VPM speeds of an eight-head rotary system.
Can the machine handle different vial sizes and cap types?
Yes. The Harsiddh Four Head Vial Sealer is highly adaptable. It can handle vial sizes ranging from 2ml to 100ml and standard cap diameters (typically 13mm or 20mm). Changeover between different vial diameters is handled via "Quick-Change" star-wheels and guide rails, allowing for minimal downtime between different product batches.
What safety and quality control features are integrated into the machine?
As a cGMP-compliant model, the machine includes several critical features to ensure product integrity:
"No Vial – No Cap" System: Sensors ensure that an aluminum cap is only released when a vial is present, preventing cap wastage and potential jams.
Spring-Loaded Sealing Heads: Each head is equipped with a spring-buffer to account for slight height variations in glass vials, preventing vial breakage during the sealing process.
Total Enclosure: The machine is housed in a transparent acrylic safety cabinet with interlock switches that stop operation if the doors are opened, maintaining a safe and clean environment.
