Monoblock for filling and closing PE/Al tubes 15-250ml
When packaging creams, gels, or viscous products into tubes, you need a system that can accurately dose, orient, and seal different tube types without long changeover times. A compact monoblock system allows you to combine these steps into one controlled process.
Fill, position, and seal tubes in one automated process
The tube filling and sealing monoblock from Omniprojekt is a carousel-based system designed to fill and close plastic (PE/PVC/laminate) and aluminium tubes with creams and semi-solid products. The machine integrates tube orientation, dosing, and closing into a single compact unit, supporting both semi-automatic (OT.205) and fully automatic (OT.301) configurations.
Empty tubes are positioned in rotating nests on the carousel, where they are oriented based on printed markers to ensure correct alignment for filling and sealing. The system can handle 12–14 tubes per cycle, depending on the configuration. Product dosing is performed using a servo-driven linear actuator, allowing electronic adjustment of fill volume between 15 and 250 ml, with high repeatability and dosing accuracy.
For plastic tubes, the system uses a thermal welding module, where the tube end is heated, sealed, and trimmed to create a clean and consistent closure. For aluminium tubes, a lacing module mechanically folds and seals the tube end, ensuring a secure closure without leakage. The machine automatically switches between modules depending on the tube type.
The system supports a wide range of products, including toothpaste, pharmaceutical ointments, cosmetic creams, gels, shampoos, adhesives, and food products such as ketchup or mayonnaise. Tube formats include cylindrical, oval, conical, and specialised shapes such as cartridges or mascara tubes.
With capacities of up to 1,000 tubes/hour (OT.205) and 2,000 tubes/hour (OT.301), the machine is suited for both small-batch production and continuous industrial use. The system is controlled via a Siemens HMI with PLC, enabling monitoring, parameter adjustment, and remote access in line with Industry 4.0 requirements.
The compact footprint (approx. 1000 × 1500 × 2000 mm) allows installation in space-constrained production areas, while modular design supports fast format changeovers within 15–20 minutes.
