The metal tube filling and sealing machine is designed specifically for the packaging of metal tubes. It integrates a comprehensive suite of functions, including tube feeding, color mark positioning, automatic filling, tube folding and sealing, etc into a single unit. This machine is widely utilized for the aluminum tube packaging of various products, such as food sauces, cosmetic creams, and medicinal gels and ointments.
So, what exactly are the specifications for the tube packaging materials compatible with this equipment? Please refer to the following descriptions regarding tube types and specifications.
Tube Type | Applicability | Description |
Aluminum tubes | Compatible | Metal type tubes |
Plastic tubes | Incompatible | Use a different tube-sealing method |
Laminate tubes | Incompatible | Use a different tube-sealing method |
Parameter | Range | Description |
Max. tube diameter | ≤ 35mm | Require a mold change for different diameters |
Max. tube length | 220mm | Maximum allowable tube length |
Filling volume | 5–300ml | Supported by piston cylinders of various specifications |
Important Notes:
• Varying tube diameters necessitate corresponding changes in mold dimensions; please specify the required tube diameter in advance.
• Varying filling volumes require the configuration of specific piston cylinder sizes; please specify the required filling volume in advance.
This series of filling and tail-sealing machines incorporates a wide range of functions. During operation, the equipment executes the entire process in a specific sequence by following the program parameters configured on the PLC.
A [Tube Feeding] → B [Color Mark Positioning]
B → C [Automatic Filling]
C → D [Tail Folding & Sealing]
D → E [Batch Number Embossing]
E → F [Automatic Finished Product Ejection]
Station | Function | Description |
Tube feeding | Manual/Automatic insertion | Semi-automatic models utilize manual insertion; fully automatic models utilize automatic insertion. |
Color mark positioning | Print alignment | Ensure consistent orientation of the printed pattern on the tube. |
Automatic filling | Quantitative filling | Fill volumes ranging from 5 to 300 ml, controlled by a piston cylinder. |
Tail folding | Metal tube sealing | Execute the folding action to fold, compress, and seal the tube's tail end. |
Batch number embossing | Coding/Marking | Create a permanent, non-fading identification mark. |
Tube discharge | Automatic discharge | Automatically eject the finished tube once the filling and sealing process is complete. |
The sealing method for metal tubes (aluminum tubes) differs from that used for plastic or laminated tubes:
Comparison Aspect | Metal Tubes | Plastic/Laminated Tubes |
Sealing method | Tail folding (Fold & Compress) | Heat Sealing (Heat Fusion) |
Sealing principle | Mechanical folding + Compression | Thermal Bonding |
Sealing effect | Secure, irreversible | Secure |
Appearance | Folded creases | Flat heat-sealed line |
Metal tube filling and sealing machines are available in both semi-automatic and fully automatic models, designed to accommodate varying customer requirements regarding production speeds and procurement budgets.
Comparison Criteria | Semi-Automatic Model | Fully Automatic Model |
Tube loading method | Manual insertion | Automatic insertion |
Production efficiency | 10–30 tubes/minute | 30–55 tubes/minute |
Degree of automation | Semi-automatic | Fully automatic |
Applicable scenarios | Small-batch, multi-variety production | Large-batch, scaled production |
Investment cost | Lower | Higher |
Compared to aluminum-plastic laminate tubes and plastic tubes, metal tubes offer superior barrier properties and excellent resistance to oxidation. Consequently, many manufacturers of food sauces, cosmetic creams, and pharmaceutical ointments opt for this packaging material, thereby creating a demand for this type of tube filling and sealing machine. The following provides a brief overview of typical applications.
Industry | Product Examples | Typical Capacities |
Food | Chocolate sauce, honey, condensed milk, etc | 20–200 ml |
Cosmetics | Hand cream, lip balm, eye cream, sunscreen, etc | 15–100 ml |
Pharmaceuticals | Ointments, gels, antibiotic creams, etc | 5–50 ml |
The metal tube filling and sealing machine is one type of the tube filling sealing machine, only applicable for the metal tube package. It achieves tube sealing through a folding mechanism and integrates the entire workflow from tube feeding to tube discharging into a single unit. Suitable for filling volumes ranging from 5 to 300 ml and tube diameters of ≤35 mm, this machine is widely utilized for food sauces, cosmetic creams, and pharmaceutical gels and ointments in metal tube packages.
