Automatic Servo Based Ampoule Filling & Sealing Machine
Next-Gen Sterile Filling & Sealing
The Harsiddh Automatic Servo Based Ampoule Filling & Sealing Machine represents the gold standard in pharmaceutical injectable packaging. By replacing traditional mechanical cams with advanced Servo-driven volumetric piston pumps, this machine offers superior control over fill volumes ranging from 0.5ml to 25ml. It is engineered to handle both open and closed-mouth glass ampoules with minimal changeover time, making it an ideal choice for high-precision, multi-product manufacturing facilities.
Operational Precision & Process Flow
The machine follows the Slant Travel Principle, which provides maximum stability regardless of the ampoule’s neck dimension or glass thickness.
Sequence of Operation:
- Automated Loading: Sterile ampoules are loaded into the slant hopper and indexed via a star wheel and eccentric rack synchronization.
- Nitrogen Purging: Pre-filling gassing removes oxygen to prevent product degradation.
- Servo-Filling: The servo-controlled pumps dispense the exact liquid dose with digital precision and high repeatability.
- Heating & Sealing: Ampoules undergo post-gassing followed by pre-heating and final sealing using a calibrated mixture of LPG and Oxygen.
- Smart Collection: Successfully processed ampoules are collected in a vertical tray unit, ready for downstream inspection.
Why Choose Servo Automation?
Servo technology allows for “On-the-Fly” volume adjustments and provides better torque control, which reduces the mechanical stress on the dosing pumps. Whether you require a single-head unit for specialized batches or an eight-head system for high-volume production of up to 250 ampoules per minute, Harsiddh’s servo models deliver optimum performance and validated reliability.

Frequently Asked Questions
How does the Servo Motor improve dosing accuracy for expensive injectables?
In this machine, the filling pumps are driven by independent Servo Motors. This allows the operator to set the exact fill volume directly through the HMI (Touchscreen). The system can achieve a high-precision dosing accuracy of ±0.5% to 1%. Additionally, the "diving depth" of the needles can be programmed to match the specific geometry of the ampoule, ensuring "bottom-up" filling to prevent foaming.
Does this machine support "Recipe Management" for different ampoule sizes?
Yes. One of the standout features of the Harsiddh Servo model is its Recipe Memory. You can store specific parameters for various ampoule sizes (1ml, 2ml, 5ml, 10ml, etc.) in the PLC. When switching batches, the operator simply selects the pre-saved recipe, and the machine automatically adjusts the stroke length and timing, significantly reducing Changeover Downtime.
How is the sealing quality maintained at high production speeds?
The machine utilizes the "Draw-off Sealing" method combined with precision gas control.
Pre & Post Nitrogen Flushing: Servo-controlled gassing needles ensure precise oxygen displacement to protect sensitive drugs.
Oxygen-LPG Burners: The flame intensity is consistent, and because the vertical movement is servo-smooth, the glass is heated uniformly.
Consistent Dome Seal: The mechanical "draw-off" grippers pull the waste glass away at a programmed speed to ensure a perfect, rounded hermetic seal every time.
What are the key cGMP and safety features of the Servo model?
As a top-tier cGMP-compliant unit, the machine is designed for the most rigorous pharmaceutical environments:
No Ampoule – No Fill: Advanced sensors ensure no liquid is dispensed if an ampoule is missing.
Materials: All contact parts are SS 316L, and the non-contact structure is SS 304.
Safety & Monitoring: The machine features a full acrylic safety cabinet with interlocks and real-time diagnostic alerts on the HMI, allowing for instant troubleshooting and data logging for batch records.
