Grün VPMC Pro Series Sorting System

The deep sorting of plastic flakes presents a critical challenge: specialty polymers such as PETG, PPSU, and TRITAN are visually almost indistinguishable from standard PET flakes, posing a key limitation for conventional polymer identification methods. Yet even trace contamination from these "look-alike" materials can disrupt melt processing stability, compromise mechanical properties, and even render entire recycled batches unsuitable for high-value manufacturing requirements. For plastic recycling and manufacturing enterprises, the ability to effectively separate these visually similar but chemically distinct polymers, while simultaneously completing color classification, is the key to producing truly pure recycled material that meets the stringent specifications of modern manufacturing.

The Grün VPMC Pro Series is a machine-vision-based sorting system tailored for this exact scenario. It employs deep fusion of state-of-the-art 3-band InGaAs-SWIR (short-wave infrared) imaging and high-resolution RGB (HR-RGB) VIS imaging, featuring the unique capability to achieve high-purity separation of PETG, PPSU, and TRITAN from PET. Through real-time scanning and surface feature analysis of plastic flakes, combined with high-performance air ejectors, it simultaneously sorts by polymer type and color difference. Compared to 2-band SWIR sorting systems, it can efficiently identify and recover more target polymers and target-color plastic flakes from the material stream within milliseconds.
