Automatic Aluminum Tube Filling Machine
Experience high-precision automation with the Harsiddh Automatic Aluminum Tube Filling Machine (HTF-40AL). This fully automatic rotary system is meticulously engineered to handle the filling, crimping, and batch coding of aluminum tubes. It is the ideal solution for high-viscosity products such as ointments, creams, pastes, adhesives, gums, and balms in the pharmaceutical, cosmetic, and chemical industries.
The HTF-40AL features a robust 12-station manifold indexing turret, providing a smooth, high-speed workflow that ensures every tube is perfectly oriented, filled, and sealed to the highest quality standards.
Precision 12-Station Workflow
The machine executes a seamless sequence across its 12 stations to ensure efficiency and product integrity:
- Cassette Feeding: Automatic feeding of empty aluminum tubes into the holders.
- Orientation: Utilizes a Stepper Motor and Datalogic ‘I’ Mark Sensor to rotate the tube for perfect alignment of the artwork.
- Hygienic Cleaning: Interior cleaning of the tube to ensure zero contamination (Optional).
- No Tube – No Fill: Advanced electrical logic sensors detect tube presence; if a tube is missing, the dosing station is bypassed.
- Accurate Filling: A volumetric piston pump provides precise dosing with a pneumatic tail-cut off for a drip-free, clean finish.
- Sealing & Crimping: High-performance Festo (Germany) pneumatic crimping unit performs 2 to 3 secure folds as required.
- Batch Coding: Simultaneous embossing of batch numbers and expiry dates on the sealed tail.
- Automated Discharge: Duly filled and crimped tubes are automatically ejected for final packaging.

Frequently Asked Questions
What is the production capacity and tube size range for this machine?
This automatic model is designed for high-efficiency production, typically achieving an output of 30 to 50 tubes per minute (approx. 1,800 to 3,000 per hour). It is highly versatile and can handle aluminum tubes with diameters ranging from 10mm to 35mm and lengths up to 200mm. The rotary indexed table allows for smooth transitions between the filling, folding, and ejection stations.
How does the machine ensure accurate filling without air bubbles?
To maintain pharmaceutical and cosmetic standards, the machine uses:
Bottom-Up Filling: The filling nozzle enters the tube and retracts as the product is dispensed. This prevents air entrapment and "tunneling" within the cream or gel.
Positive Shut-off Nozzle: A specialized "blow-back" or "cut-off" nozzle prevents dripping or "tailing" of the product, ensuring the sealing area remains clean for a perfect fold.
Dosing Accuracy: Equipped with a high-precision volumetric piston pump, achieving an accuracy of ±1%.
Does the machine include automatic tube orientation (I-Mark registration)?
Yes. To ensure a professional aesthetic, the machine is equipped with an Automatic Eye-Mark (Photo-Electronic) Registration System. Before filling, the machine rotates each tube until the sensor detects the "I-Mark." This ensures that the tube tail is folded in perfect alignment with the front-facing graphics and branding on the tube body.
What are the key cGMP and safety features of this model?
As a cGMP-compliant unit, the Harsiddh Automatic Aluminum Tube Filling Machine includes:
Material Integrity: All product contact parts (hopper, pump, and nozzles) are made of SS 316L, while the main frame is SS 304.
No Tube – No Fill Sensor: An electronic interlock prevents the pump from discharging product if a tube is missing, eliminating wastage and mess.
Safety Cabinet: The rotary table is housed within a transparent safety enclosure with interlock sensors that stop the machine if the doors are opened during operation.
Batch Coding: An integrated coding station allows for the embossing of Batch Numbers, Mfg. Dates, and Expiry Dates directly onto the crimped tail of the tube.
