At Fakuma 2024, Arburg is set to demonstrate a groundbreaking advancement in sustainable manufacturing: the processing of "paper pearls" on standard Allrounder machines. This innovative injection moulding process, developed in collaboration with paper and cardboard packaging manufacturer Model, opens up new possibilities for paper fiber-based products across various industries
The Technology
The star of Arburg's exhibit is the electric Allrounder 370 A, which will produce positioning tools for furniture connectors using paper pearls instead of conventional plastic granules
This technology combines traditional paper manufacturing with cutting-edge injection molding, significantly expanding the range of sustainable and environmentally friendly products
Paper pearls contain over 50% fibre content, consisting of primary or secondary paper fibers mixed with bio-based and biodegradable plastic
This composition eliminates the need for petroleum-based plastics, making the end products compostable and environmentally friendly
Production Process
The production cell at Fakuma 2024 will feature an energy-efficient Allrounder 370 A Comfort machine with a clamping force of 600 kN. The machine utilizes the Gestica control system, which includes several assistance functions for optimal performance:
aXw Control EnergyAssist for energy-efficient production
aXw Control RecyclatePilot for stable shot weight
aXw Control PressurePilot for bionically optimized pressure control
The exhibit will produce Slot Lock positioning tools using a 2-cavity mold from Lercher, with a cycle time of approximately 60 seconds. A Multilift Select 8 linear robotic system will handle part removal and placement.
Sustainability and Applications
The paper injection molding process offers numerous advantages:
Sustainable alternative to petroleum-based plastics
Compostable end products
Minimum wall thickness of 3 mm due to high fiber content
Applicable in furniture, cosmetics, household goods, and toy industries
