This Vietnam facility utilizes a specialized dual-line system to process electronic waste. Boxin provided two independent washing lines to recycle PS IC Trays and PET IC Trays separately, preventing material cross-contamination.
Challenge: Material Separation
The client collects mixed electronic packaging waste (IC Trays). The biggest challenge is that both PS (Polystyrene) and PET (Polyethylene Terephthalate) are heavier than water (sinkers).
- Density Issue: Since both materials sink, they cannot be separated by water density in a float-sink tank.
- Cross-Contamination: Mixing PS and PET flakes would ruin the downstream pelletizing process due to different melting points.
- Label Residue: IC trays often have sticky barcodes that require intense friction to remove.
The Solution: Parallel Lines
To solve the separation issue, Boxin deployed two dedicated lines. This allows the client to process PS trays on Line A and PET trays on Line B simultaneously or in batches.


Process Detail: Sticker Removal
Electronic trays typically come with adhesive labels. Both lines are equipped with Boxin's high-speed friction washers running at 1200 RPM. The intense friction effectively scrubs off paper labels and glue residue, ensuring the final PS and PET flakes are clean and ready for high-quality granulation.
