Automatic Eight Head Ampoule Filling & Sealing Machine

High-Capacity Sterile Packaging for High-Volume Injectable Production

In the highly regulated world of pharmaceutical manufacturing, speed must never compromise sterility or accuracy. The Harsiddh Automatic Eight Head Ampoule Filling & Sealing Machine (Model HFS-8) stands as an industry-leading flagship solution engineered specifically for high-capacity parenteral manufacturing lines. Built to excel under continuous operational demands, this robust system integrates advanced mechanical synchronization with modern automation to deliver flawless filling and airtight hermetic sealing for glass ampoules.

Utilizing the internationally proven Angle Travel Principle, the HFS-8 offers exceptional versatility, seamlessly handling an extensive range of open-mouth glass ampoules from 1ml up to 10ml without requiring extensive modifications. Equipped with an advanced eight-head configuration, the system achieves an impressive output of 80 to 225 ampoules per minute. This high-velocity output makes it the definitive choice for pharmaceutical companies looking to maximize throughput, reduce operational overhead, and maintain absolute compliance with stringent cGMP guidelines.

The Core Advantages of the HFS-8

When investing in liquid injectable packaging machinery, long-term reliability and precise validation are non-negotiable. The Harsiddh Model HFS-8 is engineered from the ground up to address the common bottlenecks of sterile filling lines:

• Unparalleled Processing Speed: Deliver between 80 and 225 perfectly sealed units per minute, keeping your large-scale manufacturing batches on track and moving efficiently.
• Dynamic Multi-Volume Versatility: Effortlessly transition between 1ml, 2ml, 3ml, 5ml, and 10ml open-mouth glass ampoules with minimal changeover parts, maximizing your production line’s utility.
• Contamination-Free Environment: Built with premium-grade stainless steel and a hands-free architectural layout, the system dramatically lowers the risk of human-borne batch contamination.
• Superior Filling Accuracy: Advanced volumetric piston pumps guarantee ultra-precise dosing, eliminating expensive product giveaway and ensuring strict uniformity of content.

Operational Precision: The Step-by-Step Sequential Process

The HFS-8 operates via a completely automated, synchronized sequence that guarantees a gentle, vibration-free journey for delicate glass containers. By relying on a masterfully designed cam mechanism, the ampoules travel smoothly through each critical processing station to eliminate breakage and product loss.

1. Infeed and Sorting Stage

Sterilized glass ampoules are loaded directly onto the machine’s integrated, inclined slant hopper. From here, a synchronized star wheel or a highly structured cassette magazine safely picks up the ampoules, aligning them into a perfect vertical position for index-based movement.

2. Pre-Gassing Phase

To safeguard oxygen-sensitive formulations against oxidation and degradation, the ampoules undergo immediate pre-nitrogen flushing. This process drives out the ambient atmospheric air inside the container, replacing it with an inert gas shroud.

3. Precision Multi-Head Liquid Dosing

The ampoules advance to the heart of the machine, where an eight-head configuration descends simultaneously. Utilizing a highly accurate volumetric piston pump system, the liquid is discharged uniformly. A specialized “no-ampoule, no-fill” sensor array ensures that no product is wasted if a slot is vacant.

4. Post-Gassing and Pre-Heating

Immediately after filling, a post-nitrogen purging cycle locks in the inert environment. The ampoules then glide into a pre-heating zone. Here, the glass tips are progressively heated, preparing them for a smooth, uniform seal without structural shocking or thermal fracturing.

5. Hermetic Fuse Sealing

The heated ampoule tips move directly into the primary sealing station. Using a precisely calibrated mixture of Liquefied Petroleum Gas (LPG) and Oxygen, the open-mouth tips are melted down and drawn off neatly, leaving a smooth, hermetically sealed finish completely free of cosmetic defects or pinholes.

6. Automatic Discharging

Once sealed and verified, the finished ampoules are smoothly guided away from the hot zone and discharged automatically into a structured vertical tray collection unit, ready for immediate optical inspection and secondary cartoning.

Advanced Technical Architecture & Engineering Excellence

The Model HFS-8 is a testament to sophisticated mechanical engineering, balancing high-speed movement with delicate handling requirements.

Single Motor Synchronization

A defining technical advantage of the HFS-8 is its central drive system. All processing stages—from infeed star wheels and indexers to the filling pumps and discharge units—are synchronized by a single, high-torque main motor. This eliminates timing drift across stations, ensuring that every mechanical component acts in perfect harmony, even when operating at peak speeds.

Variable Speed Control via Delta VFD

Production needs change based on liquid viscosity, ampoule size, and operator availability. The HFS-8 is outfitted with a cutting-edge Delta Variable Frequency Drive (VFD). This system gives operators the power to step up or dial back production speeds smoothly with the turn of a dial, preventing sudden mechanical jerks and preserving the longevity of the drive train.

Ergonomic Hygiene & Accessibility Design

Sterile environments require meticulous cleaning protocols. The architecture of the HFS-8 features a spacious layout with large open channels at the base of the frame. This smart design facilitates fast washdowns, prevents liquid or glass debris accumulation, and provides maintenance engineers with complete, unobstructed access to internal sub-assemblies.

Customizable Upgrades for Specialized Formulations

To future-proof your investment, Harsiddh offers a suite of high-tech modular upgrades that allow you to adapt the HFS-8 to highly sensitive or specialized biochemical formulations:

• PLC Touch Screen HMI: Upgrade to a smart PLC controller (Siemens or Allen-Bradley) featuring a vibrant, user-friendly touchscreen interface. This setup allows for digital recipe storage, real-time batch logging, diagnostic alerts, and full 21 CFR Part 11 compliance tracking.
• Servo-Driven Filling Systems: For maximum flexibility, replace standard mechanical links with precision servo motors. This allows operators to adjust filling volumes digitally via the interface screen in seconds, eliminating manual mechanical calibrations.
• Peristaltic Pump Integration: When dealing with shear-sensitive biopharmaceuticals, high-value proteins, or highly corrosive liquids, the machine can be configured with advanced peristaltic pump systems, ensuring the product only touches medical-grade disposable tubing.
