PET And PS （IC）Pallet Washing Line - Vietnam

This project was initiated by a Korean company investing in Vietnam, serving a recycling program for IC trays used by Samsung Electronics' facilities in Vietnam.

Initially, the client planned to operate two independent recycling lines to process both PET pallet and rigid plastics—one category being IC trays made of PS (polystyrene), used in electronic component packaging. The goal is to produce recycled plastic flakes or pellets.

Location: Vietnam (Investor from South Korea)

Partner: Samsung Electronics Vietnam Line

Capacity: Two recycling lines, each 2,000 kg/h Main

Raw Materials: PET trays, PS trays (IC trays), and modified engineering plastics

Target Product: Washed and crushed plastic flakes

Project Challenge: Unknown Material Properties → Operational Issues

At the early stage of the project, the customer did not have accurate data on the physical properties of the IC trays—such as density, whether they were modified, or their brittleness. During actual operation, the following problems occurred: Float-Sink Separation Failure: The IC trays had a density close to water, causing them to remain suspended mid-layer in the float-sink tank, making accurate material separation ineffective. High Brittleness: The trays fragmented excessively during crushing, producing large amounts of fine powder. This led to blockages in pipelines and filtration systems.

Boxin’s Response Strategy: On-Site Technical Assessment and Custom Non-Standard Optimization

After receiving feedback from the customer, Boxin took the issue seriously. The company’s CEO and Technical Director personally visited the client site in Vietnam, conducting several days of hands-on testing and problem diagnosis. The improved operational results can be viewed in the demo video at the bottom.
