ZHANGJIAGANG BOXIN MACHINERY CO., LTD.

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.

Line A (PS Tray)Specialized Crushing for Brittle PS

Line B (PET Tray)High-Friction Washing for Labels

Drying SystemAdvanced Dewatering for Surface Moisture

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.

FAQ: IC Tray Recycling Insights

Q1: Why do I need two separate lines for PS and PET trays?

A: This is crucial. Both PS (density ~1.05) and PET (density ~1.38) are heavier than water, meaning they both sink. You cannot separate them using a standard sink-float tank. Therefore, we recommend processing them on separate lines (or strictly separated batches) to avoid cross-contamination that would ruin the final pellets.

Q2: Can the machine handle the sticky labels on IC trays?

A: Yes. Labels on electronic packaging are often stubborn. Boxin's lines utilize a "Hot Washing + High-Speed Friction" combination. The hot water softens the glue, and the high RPM friction washer mechanically scrubs the paper pulp off the plastic flakes.

Q3: How do you ensure the PS trays don't shatter into dust?

A: PS trays are brittle. Standard crushers create too much fines/dust (material loss). We equip the PS line with a specialized rotor design and lower RPM crusher to shear the material rather than smash it, minimizing dust generation and maximizing flake yield.

Q4: What capacity options are available for tray recycling?

A: For IC trays, we typically offer lines ranging from 500kg/h to 3000kg/h. This Vietnam project is a high-capacity setup designed for continuous 24/7 operation.
