Automatic Two-Head Ampoule Filling & Sealing Machine

High-Precision, Sterile Liquid Packaging Technology for Pharmaceutical Lines

In modern pharmaceutical manufacturing, maintaining absolute sterility, structural accuracy, and operational efficiency during liquid injectables packaging is critical. The Automatic Two-Head Ampoule Filling & Sealing Machine from Harsiddh Unimach Pvt. Ltd. is an advanced, compact solution engineered to meet these demanding industry standards. Designed specifically for small-to-medium batch processing and pilot manufacturing lines, this specialized machine offers an automated, reliable, and highly sterile environment for filling and sealing glass ampoules with liquid injectables.

By combining precision engineering with a robust, synchronized mechanical architecture, this system ensures that delicate glass containers are handled safely, filled accurately, and hermetically sealed to preserve the integrity of the medical formulations.

Technical Specifications & Capabilities

Understanding the exact capabilities of processing equipment is crucial for manufacturing planning. The structural and operational specifications of this dual-head system include:

• Production Speed: Capable of processing 30 to 40 ampoules per minute (depending on the fluid viscosity, container dimensions, and gas flushing duration), making it ideal for targeted, high-value pharmaceutical production.
• Container Range: Exceptionally versatile, designed to seamlessly handle open-mouth glass ampoules ranging from 1ml to 25ml in capacity.
• Material Construction: The external structure, functional enclosures, and processing components are fabricated from premium, corrosion-resistant Stainless Steel (SS) to strictly adhere to Current Good Manufacturing Practices (cGMP).
• Drive Mechanics: Driven by a centralized, single synchronized motor assembly that governs all sequential operations, eliminating mechanical lag and reducing wear over extended operation.

Core Engineering Features & Advantages

1. Synchronized Monoblock Architecture

The foundation of the machine relies on a heavy-duty stainless steel frame designed to absorb mechanical vibrations during continuous high-speed cycles. A single synchronized motor drives the entire system. This means that the feeding, gas flushing, volumetric filling, heating, and final sealing mechanics move in absolute harmony. The direct result of this centralized synchronization is smooth, steady, and vibration-free rotation of the glass ampoules at the sealing station, ensuring uniform heat distribution and a perfect, hermetic seal every single time.

2. The Slant Travel Handling Principle

Glass ampoules are naturally delicate and can exhibit minor dimensional variances across different manufacturing batches. To mitigate this, Harsiddh Unimach Pvt. Ltd. implements the slant travel principle for container transportation. By moving the ampoules along a precisely calculated inclined path, the machine accommodates variations in glass thickness, neck dimensions, and base shapes. This design feature drastically minimizes mechanical stress on the glass, lowering the risk of micro-fractures or structural failure during transport.

3. Rapid Changeover with Minimal Tooling

In dynamic pharmaceutical facilities, the ability to switch between product lines quickly is a significant competitive advantage. This dual-head system is engineered with minimized changeover parts. Moving from a 2ml ampoule batch to a 10ml run requires very few component replacements, reducing machinery downtime, simplifying operator training, and maximizing overall equipment effectiveness (OEE).

4. Smart “No Ampoule, No Filling” Safety Mechanism

To protect high-value, sterile liquid formulations from unnecessary waste and to prevent operational messes on the conveyor bed, the machine features an intelligent automated sensor array. If the system detects a gap or a missing container on the transport rack, the filling pumps for that specific cycle are instantly bypassed. The line continues to run without interruption, but no liquid is dispensed until a container is securely positioned in the filling zone.

5. Multi-Stage Single-Rack Processing

Contamination control is paramount in sterile filling operations. This machine executes five distinct, critical processing steps while the ampoules are secured on a single rack stoppage, preventing exposure to external atmospheric changes during transport:

• Pre-Gassing: Flushing the empty container with inert gas (such as nitrogen) to displace oxygen and protect oxygen-sensitive formulations from degradation.
• Liquid Injection: Delivering a precise, volumetric dose of the liquid injectable via high-efficiency syringes.
• Post-Gassing: A secondary inert gas flush directly over the liquid level to eliminate any remaining oxygen head-space before sealing.
• Pre-Heating: Gradually warming the ampoule neck with precise gas burners to prepare the glass for manipulation.
• Hermetic Sealing: Utilizing a smooth draw-off sealing mechanism to fuse the glass tip shut, creating a contamination-proof barrier.

Streamlined Operational Workflow

The structural efficiency of the machine is best demonstrated through its continuous, step-by-step handling process, which completely removes human contact from the filling and sealing zone:

1. Infeed and Loading: Open-mouth glass ampoules are loaded directly into the high-capacity, stainless steel slant hopper. The incline naturally aligns the containers as they feed down toward the processing line.
2. Friction-Free Transfer: An eccentric, custom-profiled transport rack works in tandem with a synchronized star wheel to gently lift and position individual ampoules. This specialized mechanical movement completely prevents glass-to-glass friction, drastically reducing the risk of hairline fractures, scuffing, or breakage.
3. Sequential Processing Stations: Safely cradled by the transport rack, the ampoules advance through the localized pre-gassing, liquid filling, and post-gassing needles. The filling syringes deliver clean, drip-free cuts to maintain absolute accuracy and keep the ampoule necks completely free of residue.
4. The Sealing Phase: Moving to the final station, the ampoules are rotated continuously while exposed to a balanced mixture of Oxygen and LPG/Hydrogen gases. As the glass reaches its melting point, a mechanical gripper draws away the excess glass tip, creating a smooth, rounded, airtight seal.
5. Outfeed Collection: The newly sealed, sterile ampoules are smoothly guided onto an integrated outfeed tray, ready for subsequent inspection, labeling, and secondary packaging stages.
