The Finished Box Max. sizes depend on the paper size. Therefore, we calculate the limits as A(Min.) ≤ W+2H+2T+2R ≤ A(Max.); B(Min.) ≤ L+2H+2T+2R ≤ B(Max.). In practical production, the dual-channel automatic rigid box system must strictly follow these dimensional constraints to ensure stable forming accuracy and consistent output quality.
However, operators cannot meet both the Max. sizes and the Min. sizes on the same box at the same time. Therefore, production planning should be adjusted in advance to match the selected box specification and material structure.
For slanting boxes, the cover paper folds into the bottom, and the process requires an additional bubble pressing machine to complete the finishing step. Specifically, the operator starts from the lowest point of the inner box and draws a line toward the high side based on the slanting angle. If the beveled folding cover paper falls below this line, then the system defines it as folding-into-the-bottom. Moreover, when using a dual-channel automatic rigid box in such special structures, operators should carefully adjust alignment parameters to avoid forming deviation during high-speed production.
In addition, production speed of the rigid box machine depends on box size, paper type, and greyboard materials. Therefore, different configurations directly affect overall output efficiency. Furthermore, optimized material selection and parameter settings can significantly improve throughput stability in continuous operation.
Finally, the seller does not include an air compressor. Instead, users must prepare a compressor with 8 atm (0.808 MPa) and 7.5 kW power on their own. Consequently, proper auxiliary equipment setup is necessary to ensure the dual-channel automatic rigid box system operates under stable air pressure conditions and maintains long-term production reliability.
