Advanced Optical Sorting & Decontamination in PCR Plastics
An insider look into multi-stage polymer flake washing, density sink-float tanks, and optical colour separation at our Surat manufacturing facility.
The journey from discarded industrial scrap to premium polymer granules begins with aggressive decontamination. At our Surat plant, advanced optical sorting and multi-stage purification turn raw recycled polymer streams into pristine compounding feedstocks.
Multi-Stage Washing and Friction Cleaning
Feedstocks pass through high-speed dynamic friction washers and thermal caustic baths to dissolve adhesives, labels, and external soils. Density sink-float tanks separate heavy contaminants (PET, PVC, rubber, and glass) from buoyant polyolefins.
Water treatment closed-loop systems continuously recycle process water, minimizing environmental footprint while maintaining spotless cleanliness standards.
"Purity at the flake stage is non-negotiable; even 0.05% foreign polymer contamination can cause catastrophic part failure in pressure-rated mouldings."
Colour Separation for Vibrant Polymer Compounds
Producing vibrant hues like brand-green, blue, and silver masterbatches requires uniform base flaking. High-resolution CCD cameras categorize flakes into chromatic spectrums, ensuring that dark pigments never contaminate natural and light-shade batches.
- Sink-float density segregation guarantees 99.8% polyolefin purity.
- Continuous melt degassing strips volatile organics and potential odour compounds.
- Twin-strand pelletizers yield uniform cylindrical granules with minimal fines.
