One-Stop Service For Metal Packaging 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.
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.
