Square Can Production Line

Full-auto production line for small rectangular can bodies

Square can production line allows a max. working speed of 80 cans per minute and an average working speed of 60 cans per minutes. The production line integrates multiple manufacturing procedures together, including dual-die forming, seam welding locating, dual-die expanding and forming, top flanging, top seaming, U-turn, bottom seaming. Thus, square cans will be produced.

Major features:
1. Ultrasonic sensor is adopted to welding procedure, allowing correctly positioned welding seams.
2. Dual-station expanding unit is adopted for higher uniformity and higher working efficiency.
3. Integrated flanging and seaming unit is adopted for either its bottom or top at a single time, well preventing the deformation.
4. Introducing Spanish seaming technique to reach a high seaming rate - 80 cans per minute.
5. Adopting successive rotary lid delivery structure for the achieving of stable delivery and fast delivery.

Production Process
Vertical delivery of the cans → Dual-station welding seam positioning→ Dual-station expanding → Bottom flanging → Bottom seaming → Turn can over → Top flanging → Top seaming → Finished product

Voltage Three-phase four-line 380V(can be configured according to different countries)
Power 25KW

Full-auto production line for 18L square cans

Full-auto production line is used for the production of big square cans’ bodies, whose volume could be 18L, 20L or etc. The line is fully automatic and it allows an output of 30 CPM. Full-auto production line is one of the most advanced equipment by now and is suitable for mass production of square cans.

Production Process
Vertical delivery of cans → seeking seam welding → Second seam welding and locating → Expanding → Press enforcing → Top flanging → Bottom flanging → Top seaming → Turn can over → Bottom seaming → Finished product

Technical Parameters
Applicable range 18L or 20L square cans, chemical cans, grease cans, and so on.
Output rate 30 CPM
Applicable thickness of material 0.25-0.35mm
Applicable hardness of tinplate T2, T2.5, T3 and some of T4
Dimension 19000×1680×2912mm
