We’re excited to unveil our newly designed dual-purpose sink-float separation tank—an innovative, all-in-one solution that’s reshaping plastic recycling. Engineered with durable stainless steel and a modular design, this system is built to handle both floating and sinking plastic materials efficiently within a single unit.
Designed for Versatility
What sets this tank apart is its ability to process different types of plastic using the same system, just from opposite ends. Whether you’re working with HDPE, PET, or a mix of materials, this machine adapts seamlessly to your workflow.
Step 1: Floating Plastic – HDPE
In one section of the tank, we process HDPE (High-Density Polyethylene)—a plastic known for its buoyancy. As HDPE enters the water, its lower density causes it to float to the surface, while heavier contaminants and mixed materials sink.
An integrated paddle system keeps the material moving for thorough separation, while clean HDPE is efficiently discharged from one end, ready for the next stage of washing or drying.
Step 2: Sinking Plastic – PET
Now let’s flip the process. On the opposite end, the same tank is used to process PET flakes, which naturally sink due to their higher density. These flakes settle at the bottom and are gently moved along by a screw or chain conveyor, leading them to the cleaning stage without cross-contamination.
Why It Matters
This dual-end structure means you can handle two types of plastic in one tank, reducing equipment footprint, cutting costs, and simplifying the recycling line. It’s a space-saving, cost-effective, and highly flexible solution for recyclers looking to improve efficiency without compromising on quality.
Whether you’re upgrading an existing facility or building a new line, our dual-purpose sink-float tank offers the performance, reliability, and adaptability you need to stay ahead in today’s recycling industry.
