Case Erector

Case Erector is a fully automatic machine that takes flat cardboard blanks and forms them into rigid, open-top boxes — ready for product loading — without any manual handling at any stage. 

Designed to support die-cut box styles and custom cardboard shapes, it handles the most labour-intensive step in your secondary packaging line and replaces it with a fast, consistent, and fully automated process that runs continuously at production speed.

How does it work?

① Blank feeding 

Flat cardboard blanks are stacked in a magazine — a horizontal holding rack at the back of the machine. A suction cup system picks them one at a time from the top of the stack and pulls each blank forward into the forming station. 

② Box forming 

The blank is opened from its flat state into a three-dimensional box shape. This is done by a combination of suction cups that hold the blank in position and mechanical forming plates or guides that push and fold the cardboard into shape. 

③ Flap folding 

Once the four walls are upright, the side of flaps need to be folded inward and locked into position to form the base of the box. Mechanical arms or folding rails guide each flap in sequence.

④ Outfeed and transfer 

The finished open-top box is released from the forming station and discharged onto an outfeed conveyor. From there it travels directly to the next machine in the line
