ZRAY has released a multi-size adjustable carton erecting machine built for plants that change case dimensions several times per shift. The new platform keeps the full 200–600 × 150–450 × 100–500 mm forming range on one machine and cuts tool-free changeover to under 5 minutes, with most size jumps done in 3 minutes by a single operator.

What Makes Changeover Quick

The machine uses a servo-positioned mandrel and flap guides with preset changeover recipes stored in the Siemens PLC. Switch size, recall the recipe, and the machine repositions itself; no physical tooling swap is required for single-wall boards in the standard range.

• Preset recipes for common sizes reduce operator decisions to a number pick.
• Tool-free adjustment for flap guides and the magazine width guide.
• Auto flap pre-break adapts to the new blank’s score-line position.

Where It Fits

The quick-changeover build targets e-commerce fulfillment, contract packing, and multi-SKU food and beverage plants, where a case size change used to mean a 15-minute setup and lost output. Combined with the ZRAY low carton jamming rate and CE/EAC certification, the machine handles mixed production without an extra setup technician.

The changeover comparison on a typical multi-SKU line tells the story:

On a line making five size changes per shift, the difference is roughly 30–60 extra minutes of production per day, which is the payback argument for the multi-size platform on its own.
