ARBURG Announces Digital Pilot Functions to Stabilize Injection Moulding Process for Recyclates

(IN BRIEF) ARBURG has developed new digital pilot functions to stabilize the injection moulding process for recyclates such as PIR, PCR plastics, and biopolymers, which often exhibit highly variable material characteristics. The “aXw Control ReferencePilot” and “aXw Control RecyclatePilot” functions detect irregularities in the melt and adjust the injection process in real-time, ensuring consistent mould filling and high-quality components, even with fluctuating material properties.

(PRESS RELEASE) LOβBURG, 19-May-2025 — /EuropaWire/ — ARBURG announces the development of advanced controller technology solutions designed to stabilize the injection moulding process when working with recyclates, including PIR, PCR plastics, and biopolymers. These materials often exhibit highly variable characteristics, making process stability a challenge. While virgin materials can typically be processed under stable conditions, recyclates require special adjustments to ensure consistently high-quality parts. ARBURG’s innovative digital pilot functions, the “aXw Control ReferencePilot” and “aXw Control RecyclatePilot,” stabilize the injection moulding process precisely during the injection and holding pressure phases.

Overcoming Unknown Variables in Injection Moulding

In the injection moulding of recyclates, the machine controller faces two critical unknowns: the precise composition of the material being processed and the conditions within the mould itself. The machine lacks visibility into the exact makeup of the plastic entering the mould and has no direct insight into the temperature and pressure profiles between the mould mounting platens. These “black boxes” significantly complicate process control, especially when working with recyclates, whose characteristics can vary widely and are often delivered without reliable material specifications.

To address these challenges, ARBURG’s digital assistance functions—”aXw Control ReferencePilot” and “aXw Control RecyclatePilot”—detect irregularities in the melt and actively adjust the injection process in real-time. This allows the system to compensate for fluctuations in viscosity, ensuring a stable and consistent mould filling. The result is reliable component quality, even when using recycled materials that are more difficult to process.
