Zhida Plastic Machinery
Zhida Plastic Machinery
Optimized for processing agricultural waste, post-consumer PET/HDPE, and mining-grade polymer streams across DR Congo.
The Democratic Republic of the Congo (DR Congo), with its massive population centers like Kinshasa and highly active mineral extraction basins in the Haut-Katanga and Lualaba provinces, stands at a pivotal point in industrialization. With this growth comes an exponential rise in plastic waste—particularly post-consumer PET bottles, packaging films, and highly contaminated heavy-duty PP woven bags used in mining operations.
However, local recycling plants face unique, severe operational challenges. Power grids are frequently unstable, meaning machinery must withstand sudden voltage variations and run efficiently on large industrial generators. Furthermore, raw plastic materials in the Congo basin often feature high soil, mud, and dust contamination. Conventional machinery wears down in months. Our specialized granulator systems are engineered with wear-resistant bimetallic screws, dual-vacuum degassing systems, and robust motors specifically designed to maintain productivity under these localized stresses.
Established in 2018 in Ningbo, China, Ningbo Zhida Plastic Machinery Co., Ltd. has rapidly grown into one of the largest suppliers of new and premium second-hand plastic extrusion machinery. We operate on a unique dual-track business model: offering fully customized, factory-price new machinery alongside thoroughly refurbished second-hand machinery from China's top-tier manufacturers, including Jwell, BeiEr, FangLi, Jurry, and JinHu.
Our technical core is our engineering team, boasting over 15 years of hands-on experience in testing, upgrading, and maintaining plastic machinery. When you purchase refurbished equipment from us, every gearbox, motor, inverter, and pump is systematically disassembled, inspected, repaired, or replaced. We perform full-load dry and wet testing to ensure that when a machine arrives at your facility in Matadi, Lubumbashi, or Kinshasa, it operates seamlessly from day one.
How the circular economy transitions local plastic waste streams into lucrative high-grade raw polymer resins.
Across the globe, the transition towards a circular economy is no longer just an environmental ideal; it is a highly profitable industrial reality. Raw virgin polymer prices in Central Africa are among the highest in the world due to steep container shipping freight rates and complex inland logistics. By converting domestic municipal waste and mining-grade polyolefin scrap into recycled plastic pellets, Congolese manufacturing enterprises can substitute expensive imported virgin raw material and achieve a cost savings of up to 40%.
To support this transition, we offer complete industrial plant designs, including high-capacity washing lines, primary granulation lines, pulverizing and milling systems, and auxiliary color masterbatch mixing equipment. This holistic approach ensures that local operators can convert low-grade waste plastics into uniform, bubble-free, and high-density pellets suitable for immediate reuse in blow molding, pipe extrusion, and injection molding processes.
| Polymer Type | Common Local Sources in DR Congo | Recommended Granulator Process | Ideal End-Product Application |
|---|---|---|---|
| PP (Polypropylene) | Mining concentrates jumbo bags, raffia bags, crates | Twin-Screw Extrusion + Water Ring Pelletizing | Heavy industrial packaging, battery cases, new woven sacks |
| PET (Polyethylene Terephthalate) | Beverage bottles, cosmetic packaging | Single/Twin-Screw with high-vacuum degassing | Polyester fiber, high-tensile strapping bands, bottle-to-bottle sheets |
| HDPE / LDPE | Water containers (yellow jerrycans), agricultural films | Single-stage or Double-stage (baby-mother) lines | Non-pressure utility pipes, plastic lumber, agricultural sheets |
| PVC (Polyvinyl Chloride) | Construction pipes, profile trimmings, cable sheathing | Conical twin screw extrusion + Pulverizer milling | Electrical conduits, corrugated drainage tubes, shoe soles |

Tailoring extrusion processing parameters to the region's main manufacturing centers.
Mining companies in Kolwezi and Lubumbashi generate thousands of tons of high-tensile polypropylene (PP) jumbo bags (FIBCs) used to transport copper concentrates and cobalt hydroxide. These bags are highly dusty and carry chemical residues. Our solution involves a high-pressure washing pre-treatment, followed by processing on our twin-screw extruders with double degassing and heavy-duty, self-cleaning hydraulic screen changers. The resultant pellets are utilized directly by domestic packaging plants to blow new heavy industrial bags, drastically decreasing container import dependency.
Kinshasa, with a population exceeding 17 million, generates huge volumes of municipal waste. Our PET and HDPE wash-and-granulation setups allow recycling centers in the capital to feed clean, flake-free polymer output directly to local bottle-making and strap-making factories. With our energy-saving heating bands and variable frequency drives, operators can decrease power requirements by up to 25% compared to local custom-assembled machines.
The urban real estate boom in Goma, Lubumbashi, and Kinshasa has accelerated demand for water management pipes. Scraps from local PVC pipe processing factories and building construction sites can be crushed, milled using our high-speed pulverizers, and compounded with customized calcium filler additives. By adjusting the formulations with our twin-screw extruder compounding machines, factories produce rigid, high-load-bearing agricultural drainage channels and domestic electric conduits at very low cost.
A structured, step-by-step breakdown of how we secure your factory’s expansion.
For second-hand machines, our sourcing teams travel weekly throughout China's key manufacturing zones, inspecting large pipe and sheet factories. We filter and only select machines built by premium brands (Jwell, BeiEr, FangLi, Jurry, etc.) that are in outstanding core mechanical condition.
Our engineers perform deep refurbishments: disassembling gearboxes, inspecting bearings, replacing worn electric elements with global-standard components (Schneider, Omron, Siemens), and repainting to the customer's color preference. Bimetallic barrels and screws are verified for tolerance limits.
Prior to shipment, the machinery undergoes strict load trials. We run identical polymer materials and measure extrusion pressure, melting temperature, and motor current stability. We record comprehensive test run videos and measurements, sharing them directly with the buyer for full approval.
We coordinate secure container loading and port delivery. For customers in western DR Congo, we ship directly to Matadi Port. For Katanga/southern regions, we route shipping containers through the corridors of Dar es Salaam (Tanzania) or Mombasa (Kenya) to Lubumbashi.
We supply detailed mechanical wiring diagrams, foundation dimensions, and operations manuals. Upon request, we deploy senior technicians to DR Congo to guide installation, troubleshoot the commissioning phases, and train your local labor force on optimal machine usage and preventive maintenance.
A key failure point in recycling plants is the absence of replacement wear parts. We keep a robust inventory of critical spares: heating bands, heater solid-state relays, wear blades, screen filters, screws, and barrels, dispatching replacements via air express to ensure minimal downtime.
