Fakuma 2024: ALLROUNDER 370 A

At Fakuma 2024, ARBURG (Hall A3, Stand 3101) will be demonstrating how so-called "paper pearls" can be reliably processed on standard ALLROUNDERs instead of conventional plastic granules. The innovative injection moulding process paves the way for new, paper fibre-based applications and products in a wide range of industries, including the furniture industry. The exhibit, an electric ALLROUNDER 370 A, will be producing positioning tools for furniture connectors by way of example. The "aXw Control RecyclatePilot" integrated into the GESTICA control system ensures a stable shot weight by evening out variations from one material or batch to the next.

Sustainable: Paper fibres instead of petroleum

Paper injection moulding and the development of paper pearls have been advanced by ARBURG together with Model, a paper and cardboard packaging manufacturer. The technology combines the long tradition of paper with the latest injection moulding technology, significantly expanding the range of sustainable and environmentally friendly injection moulded products for a wide range of applications. The fibre content of the paper pearls is over 50 per cent. The main component is primary or secondary (i.e. new or recycled) paper fibres that are combined with biobased and biodegradable plastic to make them injection mouldable. There is no need at all for any petroleum-based plastics. Due to the high fibre content, the end products should have a minimum wall thickness of three millimetres. They can be easily disposed of in a garden compost heap after use because they contain no additives that could interfere with the composting process.

High quality: Electrical machine technology

At Fakuma 2024, an energy-efficient production cell built around an ALLROUNDER 370 A "Comfort" with a clamping force of 600 kN will be demonstrating the stable and reliable production of injection-moulded parts made from paper pearls. The GESTICA control system used has several assistance functions. "aXw Control EnergyAssist" brings together all the key functions of the plasticising cylinder and mould. This ensures optimised switching on and off of all heating zones, significantly reduces the energy requirement in the heating phase and enables energy-efficient production.
