ISHITVA® Flake Sorter
In plastic recycling, purity is profit. Even a few contaminated flakes can reduce batch value, impact quality, and increase rejections. That’s why visual inspection or random sampling is no longer enough.
Sort by Polymer. Sort by Color.
NIR + Color/UV
Ishitva’s Flake Sorter
The Ishitva® Flake Sorter features a powerful combined sensor suite that integrates NIR, UV, color imaging, and AI for the precise detection and separation of foreign polymers and colors, even in fine flakes from 2mm to 20 mm.
Enables accurate material identification and ensures sorting performance that consistently achieves targeted PPM purity levels aligned with global standards. Requires minimal setup and offers seamless integration into existing lines with flexible configuration options for diverse polymer applications.
Why Ishitva’s Flake Sorter?
- Detects and ejects foreign polymers like HDPE, PP, BOPP labels, ABS, and degraded PET that manual or visual checks often miss.
- Enables recyclers to consistently reach <30 PPM contamination, essential for food-grade and bottle-to-bottle applications.
- Ensures uniform flake quality across batches, reducing rejections, debit notes, and buyer disputes.
- Accurately separates off-color and degraded flakes, increasing resale value and buyer confidence.
- Prevents foreign polymers from entering extrusion and filtration systems, reducing breakdowns and maintenance costs.
Key Capabilities
For PET Flakes
- Detects and separates unwanted polymers (HDPE, PP, PVC, PC, etc.)
- Identify and eject flakes with unwanted colors (Green, Brown, Black, Red, Orange, Yellow, degraded PET)
- Detects and separates metal fines coming from caps, closures, or neck rings
- Detects and separates BOPP PVC flakes coming from labels and sleeves
- Maintain <30 PPM contamination levels
- Enable high-purity bottle-to-bottle or food-grade rPET output
For HDPE & PP Regrinds
- Separate by polymer type, color, and even as per your MFI requirements.
- Detects and separates various polymer types, including PVC, PC, HIPS, ABS, and more.
- Identify and separates label residues, films, or colored contaminants
- Ensure consistent material quality for high-value upstream applications like caps, closures, pipes, and containers.
