Grün VPMC Series Sorting System

The further sorting of plastic flakes presents a unique challenge: polymer type accuracy is just as critical as color consistency. Even a tiny fraction of cross-polymer contamination can compromise melt uniformity, mechanical properties, and the suitability of recycled material for high-value manufacturing applications. For plastic recyclers and manufacturers, the ability to efficiently sort flakes by polymer type and color in a single pass directly determines the purity of recycled output, the range of viable end-use applications, and the commercial value of recovered material.

The Grün VPMC Series is a machine-vision-based sorting system tailored for this exact scenario. It employs deep fusion of cutting-edge 2-band InGaAs-SWIR (short-wave infrared) imaging and high-resolution RGB (HR-RGB) VIS imaging to perform 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, efficiently identifying and recovering target polymers and targert-color plastic flakes from the material stream within milliseconds.
