The MDN multi-line tray stacking series is designed to accurately place containers, such as single-cavity, multi-cavity, clamshell, and custom-made trays, onto step-by-step or continuous motion conveyors. These machines are highly flexible and can be easily integrated into the customer's existing equipment. MDN machines are built with multiple tray slots to meet tray requirements and can operate at speeds up to 50 cycles per line, with quick-lock/unlock connections and minimal adjustment needs, allowing for fast changes in under 10 minutes.
