Plastic recycling sorter AUTOSORT® FLAKE

coloropticalmagnetic

Overview
AUTOSORT™ FLAKE is an optical flake sorter designed to achieve maximum purity yields for high-end plastic recycling, including bottle-to-bottle applications. It integrates a FLYING BEAM™ NIR spectrometer, a full-color camera and a high-sensitivity electromagnetic metal sensor. High-speed valves provide precise ejection of small contaminants, while integrated lighting and continuous signal correction support stable sorting performance.

Key benefits

• Consistent ultra-high purity output suitable for demanding recycled products
• High-sensitivity electromagnetic metal detection (down to ~1 mm)
• Simultaneous removal of foreign polymers, color defects and metal fragments
• Cost-effective operation with high uptime and reduced downtime
• Integrated recovery track and dust extraction for process stability

Features

• FLYING BEAM™ NIR spectrometer for polymer identification
• Full-color camera for accurate color separation
• Electromagnetic metal sensor with high sensitivity
• High-speed valves for precise ejection of very small contaminants
• Integrated light source with continuous signal correction and enhanced light distribution
• Dust extraction system
• Integrated recovery track
• Advanced statistics and real-time quality control

Applications
Designed for flake sorting in plastic recycling operations (PET and PO flakes and other polymers) to meet strict purity requirements for high-value recycled products, including bottle-to-bottle recycling.

Technology & operation
Optical sensors (FLYING BEAM™ NIR and full-color camera) work together with a high-sensitivity electromagnetic sensor to detect polymer type, color and small metal fragments simultaneously. The system uses an integrated light source with continuous signal correction to maintain stable detection. High-speed valves enable targeted ejection; electromagnetic detection reaches approximately 1 mm for small ferrous and non-ferrous fragments.
