In the rapidly evolving landscape of the circular economy, the Sink Float Tank remains the most critical component for the high-purity separation of mixed polymers. As global regulations tighten around recycled material quality, manufacturers are increasingly seeking custom OEM solutions that can handle complex waste streams with surgical precision.
At Ningbo Zhida Plastic Machinery Co., Ltd., we specialize in bridging the gap between traditional mechanical recycling and next-generation purity requirements. Our sink-float technology is engineered to exploit the minute differences in specific gravity between PE/PP (floaters) and PET/PVC/PS (sinkers).
Our OEM tanks feature adjustable turbulence zones and laminar flow stabilizers. This ensures that even thin film flakes do not get trapped in the wrong layer, maximizing recovery rates for multi-layer materials.
Using SUS304 or SUS316 stainless steel with specialized anti-corrosion coatings. Our designs are built to withstand 24/7 industrial loads and abrasive plastic contaminants.
Modern sink-float tanks are now equipped with real-time turbidity sensors and automated discharge systems, reducing labor costs and human error in the separation process.
Procurement teams in regions like Southeast Asia, North Africa, and the Middle East are shifting from "low-cost focus" to "Total Cost of Ownership (TCO)" analysis. This involves looking at water consumption, energy efficiency of the paddle systems, and the ease of sludge removal.
Ningbo Zhida Plastic Machinery Co., Ltd. was established in 2018, with its headquarters located in Ningbo, China. The company specializes in the sales and service of used/second-hand plastic machinery and is currently one of the largest suppliers of used/second-hand plastic extrusion machine in China.
Since its establishment, the company has always adhered to the principle of "integrity-based, quality first". We have successfully helped over 1000 plastic product manufacturers reduce production costs, including manufacturers from India, Morocco, Vietnam, Egypt, Pakistan, Bangladesh, Zambia, Ethiopia and other countries.
Furthermore, we have a cooperating team dedicated to the manufacturing of new machinery, which can provide you with brand new plastic machinery. Through the dual-track model of "used/second-hand machinery supply + new machinery customization", we provide our customers with one-stop and diversified plastic machinery solutions.
Our sourcing team travels throughout China weekly, maintaining relations with large pipe/profile/sheet factories. We can source specific equipment within 7 days.
A Sink Float Tank is only as good as the system it integrates with. Our macro solutions include synchronization with Plastic PP PE Film Crushing Washing Dewatering Squeezing Dryer Recycling Machines. By controlling the feed rate and flake size before it enters the tank, we ensure the flotation dynamics are optimized for maximum throughput.
We understand the complexities of international trade. Our machines comply with CE and ISO standards, and we provide localized support through our extensive network of engineers in over 10 countries. Whether it's internal threading for PPR PVC HDPE Plastic Pipes or high-efficiency PE Film Blowing, our solutions are built for global compliance.
