Automatic Tube Filling Machine MTF600 & HC20 | High-Precision

Aluminum tube sealing machine is a specialized mechanical automated equipment for the tail crimping, folding and sealing of metal aluminum tubes filled with paste, cream, viscous liquid and industrial grease products, which is a key supporting device for aluminum tube production lines in the cosmetics, pharmaceutical, food and industrial chemical industries, and is specially used for sealing pure aluminum tubes and aluminum alloy tubes with good metal ductility and hardness. This equipment is engineered to adapt to the metal material characteristics of aluminum tubes, adopting a multi-stage mechanical crimping and folding sealing technology, with core technical features of precise tube positioning, uniform crimping force, firm and airtight sealing, neat sealing shape and no aluminum tube deformation, which can effectively ensure the sealing effect of aluminum tubes, prevent product leakage and external contamination, and give full play to the excellent barrier performance of aluminum tubes, extending the product shelf life. Aluminum tubes are widely used in the packaging of high-end cosmetics, sterile pharmaceutical ointments, high-end food and industrial grease products due to their excellent barrier performance (moisture proof, oxygen proof, light proof, corrosion proof) and good mechanical strength, and thus have strict requirements for sealing equipment: the sealing must be firm and airtight to ensure the barrier performance and mechanical strength of the tube body; the crimping force must be uniform to avoid aluminum tube deformation and cracking; the sealing shape must be neat to meet the packaging requirements of products. The aluminum tube sealing machine is composed of a high-precision aluminum tube feeding and positioning system, a servo-driven multi-stage crimping mechanism, a sealing shaping and trimming device, a coding system, and an intelligent control system. The aluminum tube positioning system adopts a pneumatic clamping and precise indexing structure with adjustable clamping force, which can adapt to aluminum tubes of different specifications (diameter 8mm-50mm, length 50mm-200mm) and ensure that the aluminum tube is stably fixed without deformation during the sealing process; the servo-driven multi-stage crimping mechanism adopts a three-stage or four-stage crimping design, which can realize multi-layer folding and crimping of the aluminum tube tail (usually 3-4 layers), forming a firm and airtight seal, and the crimping force and crimping depth can be precisely controlled through the servo system, ensuring consistent sealing quality of each aluminum tube; the sealing shaping and trimming device can trim the burrs of the sealed aluminum tube tail and shape the seal to ensure a neat and beautiful appearance, meeting the product packaging requirements; the online coding system can print production date, batch number, shelf life and other information on the aluminum tube tail during the sealing process, realizing the integration of sealing and coding, improving production efficiency and product traceability. In practical production applications, this machine is closely matched with aluminum tube filling machines to form a complete aluminum tube product production line, and is widely used in various industries with different sealing requirements: in the cosmetics industry, it is used for sealing high-end cosmetic cream, eye cream and foundation aluminum tubes, with high requirements for the beauty of the sealing shape and the firmness of the seal; in the pharmaceutical industry, it is used for sealing sterile pharmaceutical ointment aluminum tubes, complying with GMP production specifications, with core requirements of sealing tightness and asepsis, and the sealing process must not produce harmful substances; in the food industry, it is used for sealing food-grade aluminum tubes filled with jam, honey and chocolate sauce, meeting food hygiene and safety standards; in the industrial chemical industry, it is used for sealing industrial aluminum tubes filled with grease, lubricating oil, sealant and paint, with high requirements for the firmness and corrosion resistance of the seal to adapt to harsh transportation and storage environments.
