Folder-Gluer Special-Shape & Lock-Bottom Box Forming: Mass-Producing Complex Boxes Efficiently

Special-shape and lock-bottom boxes are among the hardest box types, with complex structures and many folding steps. The folder-gluer achieves efficient mass production of complex boxes through the coordination of die-cut precision, folding sequence, and glue control.

Scenario: Three Difficulties in Forming Complex Boxes

Forming special-shape and lock-bottom boxes has three difficulties:

Pain Points

• Many fold lines in a complex sequence—one wrong fold ruins the box;
• Many glue points demanding precision—overflow or missed glue both hurt quality;
• Special-shape structures are hard to position, so high-speed running easily shifts or jams.

Solution: Three Forming Process Essentials

Folder-gluer forming of special-shape and lock-bottom boxes has three essentials:

1. Die-cut precision control. Precise creasing with consistent fold-line position and depth produces neat forming.

2. Folding sequence optimization. Design folding steps by box structure, with multi-stage folding that's gradual and non-conflicting.

3. Glue-point control. The gluing system applies glue precisely by point, controlling amount and position to avoid overflow or missed glue.

Result: Efficient Mass Production of Complex Boxes

With the process in place, special-shape and lock-bottom boxes can also be mass-produced efficiently and stably on a folder-gluer, lifting both yield and efficiency.
