Ampoule Filling and Sealing Machine

Ampoule filling and sealing machine is designed for high-precision, hermetic packaging of glass ampoules. It automatically completes the entire process: ampoule feeding, nitrogen purging, liquid filling, flame sealing, and finished product output. 

• Sterile & Hermetic Sealing: Uses controlled flame heating to melt and seal the ampoule neck, ensuring 100% airtight closure to preserve product stability and extend shelf life.

• Nitrogen Purging System: Reduces oxygen levels inside the ampoule before filling, preventing oxidation and protecting sensitive ingredients. 

• Precision Filling: Features multi-head dosing pumps for consistent, accurate volume control, suitable for pharmaceutical and cosmetic ampoules (1-10ml). 

• Easy Operation & Maintenance: Constructed with food-grade stainless steel for easy cleaning, with adjustable parameters for different ampoule sizes and liquid viscosities.

1. Ampoule Feeding System 

• Ampoule Hopper/Feeding Tray: The sloped metal hopper at the top is designed to hold bulk glass ampoules. 

It uses gravity and vibration to feed ampoules one by one into the production line, ensuring continuous and orderly supply. 

• Feeding Conveyor/Indexing Mechanism: Transports ampoules from the hopper to the next stations.

 It uses precise indexing to position each ampoule accurately under the filling and sealing units. 

 2. Nitrogen Purging Unit 

• Gas Flow Meters: The four transparent flow meters on the front panel regulate the flow rate of nitrogen gas into the ampoules.

 This creates an inert atmosphere inside the ampoule, preventing oxidation and preserving the stability of sensitive liquids (e.g., serums, pharmaceuticals). 

• Nitrogen Injection Nozzles: Small, precision nozzles positioned above the ampoules that inject nitrogen gas into the neck before filling. 

 3. Liquid Filling System 

• Precision Filling Pumps: The core of the filling process, these pumps are usually peristaltic or ceramic piston pumps.

 They deliver accurate, repeatable volumes of liquid into each ampoule, with adjustable ranges (typically 1-10ml for cosmetic/pharmaceutical use). 

• Filling Nozzles: Located above the ampoules, these nozzles are made of sanitary stainless steel (SUS316L). 

They extend into the ampoule neck during filling to prevent splashing and ensure clean dispensing. 

 4. Flame Sealing System 

• Gas Control Valves & Burners: The machine uses gas/oxygen flame burners to heat the ampoule neck until it softens. 

The burners are precisely positioned to melt the glass evenly. 

• Sealing Tongs/Forming Mechanism: As the glass neck softens, specialized mechanical tongs pinch and twist the top of the ampoule to form a hermetic seal. 

This creates a tamper-proof, airtight closure.

 5. Control & Operation Panel 

• PLC Control Unit: The "brain" of the machine, it coordinates all processes (feeding, purging, filling, sealing). 

It allows users to set parameters like filling volume, speed, and gas flow. 

• Control Buttons: Green start button, red emergency stop button, and pressure gauge for gas/air supply monitoring. 

• Stainless Steel Cabinet: Houses all control components, with a smooth, easy-to-clean surface that meets hygiene standards. 

 6. Frame & Structure 

• Stainless Steel Body: The entire machine is constructed from food-grade stainless steel (SUS304 for the frame, SUS316L for product contact parts), ensuring corrosion resistance and compliance with GMP standards. 

• Adjustable Feet: At the base, they provide stability and allow leveling of the machine on uneven floors.
