ALLROUNDER 520 A: Closures capped directly in the mould

At Fakuma 2024, an ALLROUNDER 520 A ULTIMIATE will be producing high-quality PP closures for personal care products. A highlight o will be servo-electric capping directly in the mould with the aid of integrated axes from ARBURG's sister company AMKmotion.

The ALLDRIVE high-performance electric series is ideal for applications in the packaging and personal care industries thanks to its precision, energy efficiency and sustainability. Servomotors from AMKmotion additionally enable high-precision mould movements. Smart functions and assistants from the GESTICA control system ensure optimised injection moulding processes, intelligent mould monitoring, a reduced energy requirement and flawless part quality.

The exhibit will be processing PP from Borealis into lightweight flip-top closures for tubes in a cycle time of around 9 s. The flip tops are automatically closed directly in the mould using in-mould closing (IMC). The part design requires special geometries with two precisely defined pressure positions. Two servo motors from AMKmotion, which are controlled at different times, play a central role in the reproducible capping process. The innovative 2-cavity pilot mould comes from VTW, Austria. The mould is fully integrated into the GESTICA control system, making it much easier for the operator to start up the machine and monitor the process sequences.

Numerous functions and assistants integrated into the control system ensure active support during work at the machine as well as optimised processes, maximum efficiency and flawless part quality: The “aXw Control CycleAssist” function makes sure the control system knows the programmed cycle. The “aXw control PressurePilot” function enables bionically optimised pressure control. The "energy display" makes the energy requirement transparent. The function "stability monitoring" reduces the reject rate, and "precision dosing" ensures precise screw control.
