Cylindrical packaging forming machines are industrial units designed specifically for processing cylindrical packaging. Their core functions cover the entire production process-from raw sheet material to the finished cylinder-with specific capabilities varying by model:
Cylinder Forming and Bonding
These machines roll sheet materials (such as PVC, PP, and APET) into standard cylinders using adhesive application or ultrasonic welding. Fully automatic models eliminate the need for manual sheet flattening or pre-cutting; material can be loaded as a continuous roll, with forming completed in a single pass. They accommodate diameters ranging from 30mm to 200mm, achieving production speeds of up to 60 units per minute.
Auxiliary Post-Processing
Cylinder curling machines perform automatic, constant-temperature curling on plastic or paper cylinders, enhancing both the structural strength and aesthetic appeal of the rim. Cylinder bottom-sealing machines utilize a four-station ultrasonic rotary table to securely bond the base cap, accommodating sealing requirements for cylinders with diameters of 60–200mm.
Integrated Line Operation and Expansion
Equipped with PLC and HMI controls, these machines can link with curling and bottom-sealing units to form a fully automated production line. Some models also integrate automatic punching functions to facilitate the subsequent attachment of handles, meeting packaging needs across diverse sectors such as confectionery, gifts, and toys.
