View SpecificationsCNC Flow Forming is an advanced cold-forming method that deforms metal symetrically over a rotating mandrel using high hydraulic force rollers. Unlike conventional metal spinning, flow forming subjects the workpiece to compressive stresses that exceed the material's yield strength, resulting in a refined grain structure, high dimensional accuracy, and significant material savings. By converting coarse grain structures into elongated, parallel arrays, flow forming improves structural integrity, achieving tensile strengths up to 30% higher than raw forgings.
For Namibia's developing industrial base, adopting precision flow forming eliminates the need for expensive, time-consuming subtractive machining processes. Standard techniques like boring or grinding raw billets generate substantial scrap waste. In contrast, ZRF's CNC Flow Spinning systems achieve up to 90% raw material utilization, translating directly to reduced input costs for specialty alloys, stainless steel, and heavy-walled carbon pipes.
Namibia is rapidly positioning itself as a regional logistics and industrial hub in Southern Africa. Key projects, including the expansion of the Walvis Bay port corridors, the growth of the Erongo gold, uranium, and lithium mining zones, and the emerging green hydrogen initiatives in the Tsau //Khaeb National Park, demand robust high-pressure fluid transportation, heavy machinery spares, and structural processing parts.
Maintaining long mining supply chains to overseas repair shops leads to costly operations downtime. Establishing local precision manufacturing capabilities using CNC flow forming machines enables Namibian fabricators to manufacture and re-sleeve heavy industrial shafts, process pipelines, and pump components locally. This regionalized supply chain reduces import dependency, lowers operational costs, and supports the nation's "Growth at Home" industrial policy.
Internationally, CNC flow forming is standard practice in high-performance sectors such as aerospace (rocket nozzles, jet engine casings), defense (artillery canisters), automotive (alloy wheels, transmission components), and power generation (gas turbine shrouds). As these fields demand higher strength-to-weight ratios, the reliance on multi-roller CNC setups (2-roller and 3-roller configurations) continues to grow.
Zhejiang ZRF Spinning Co., Ltd. bridges the gap between advanced engineering standards and cost efficiency. Operating from China's premier industrial manufacturing belt, ZRF leverages deep supply chain integration, advanced machining tooling, and highly skilled research staff to offer several distinct advantages:
Our structures are built using heavy cast iron beds and stress-relieved steel plates, ensuring maximum vibration dampening under massive hydraulic pressures (up to 600kN per roller block).
By coordinating in-house casting, CNC machining, laser profiling, and assembly, ZRF reduces typical production cycles from 9 months (Western competitors) down to just 3 to 4 months.
Every ZRF machine undergoes 120+ hours of continuous testing and alignment verification before dispatch. This is supported by our ISO 9001:2015 quality management procedures.

Deploying Zhejiang ZRF spinning machinery provides practical solutions for key industrial applications across Namibia's unique economic sectors:
Namibian mining operations run in abrasive, highly corrosive desert environments. Thick-walled slurry pipelines, rotary dryers, and heavy structural drums experience rapid wear. Utilizing our WR200-3T three-roller flow forming machinery enables local engineering firms to manufacture seamless, high-density alloy pipe sleeves and high-durability rollers that withstand sand and chemical erosion.
Ocean-going vessels and coastal salt processing systems require specialized non-corrosive copper and marine-grade stainless steel assemblies. ZRF's CNC Metal Tube End Spinning machines provide seamless expansion and end-forming on large-diameter pipes, ensuring leak-free connections in desalination pipelines and cooling loops without relying on welding.
Irrigation schemes along the Orange, Okavango, and Kunene rivers depend on heavy centrifugal pumps and robust piping. Our copper metal spinning and horizontal hydraulic forming lathes enable local production of high-efficiency fan nozzles, pump casings, and specialized adapters, significantly reducing lead times for replacement agricultural parts.
As Namibia drives forward with green hydrogen initiatives, the demand for high-integrity gas storage cylinders and lightweight structural tubes is growing. Multi-axis CNC flow forming is the primary production method for seamless pressure vessels capable of safely storing compressed gases, offering a key manufacturing solution for local clean energy projects.
Our ISO9001-certified factory in China covers the entire manufacturing sequence, from initial raw casting machining to final CNC debugging, ensuring maximum uptime and dependability on Namibian shop floors.

Procuring a CNC Flow Forming system requires assessing mechanical specifications against planned production tasks. Use these criteria when sourcing equipment:
Heavy-duty cold forming of stainless steel requires substantial force to induce plastic deformation. Ensure roller forces (axial and radial) match the maximum planned thickness of your toughest alloys.
While 2-roller systems handle general spinning, 3-roller configurations (e.g., WR200-3T) balance radial forces, preventing deflection when forming long, seamless tubes like mining conduits.
Closed-loop CNC controllers with real-time feedback adjust roller paths dynamically. This compensates for variations in material hardness, maintaining tight tolerances under 0.02mm.

Shear Spinning (Sine Law): The metal deformation aligns with the sine law. The outer diameter of the final part matches the flat blank diameter, but wall thickness is systematically reduced relative to the forming angle. It is typically used for conical geometries.
Flow Forming (Constant Volume Rule): The material is compressed and extruded over a mandrel. The starting preform has a smaller diameter than the finished part length. The cylinder wall thickness is reduced, while its length increases, maintaining a constant outer diameter. This is ideal for producing long, seamless pipes, cylinders, and tubes.
We manage complete export logistics from Ningbo or Shanghai ports directly to the Port of Walvis Bay. The machine frame is secured inside flat-rack or open-top ocean containers, treated with anti-corrosion coatings, and vacuum-sealed. Once at Walvis Bay, we coordinate with your chosen freight forwarding company for heavy-haul flatbed transport along the Trans-Kalahari or Trans-Kunene highways to your facility in Windhoek, Swakopmund, or Rosh Pinah.
Yes. Our heavy-duty CNC flow forming models, such as the WR200-3T, are engineered specifically to process thick-walled seamless pipes. The system uses high-rigidity hydraulic roller blocks to reduce the wall thickness of carbon steel, stainless steel, and specialty copper alloys, extending the pipe length while improving structural integrity. This is ideal for high-pressure slurry lines and structural mine supports.
We provide full installation, commissioning, and operator training services. Customers can send their technical staff to our production facility in Zhejiang for comprehensive pre-delivery training. Additionally, ZRF engineers can be dispatched to your site in Namibia to perform initial machine assembly, set up hydraulic systems, align axes, and train local technicians on programming, tool changes, and safety protocols.
Tooling rollers and mandrels are manufactured using high-speed tool steels (such as Cr12MoV or H13) and hardened via vacuum heat treatments to over HRC 60. When processing softer metals like copper, tool wear is minimal. When processing high-strength stainless steel, tooling inspection is recommended after 5,000 to 10,000 cycles. ZRF maintains a large inventory of standard spare parts, which can be air-freighted to Windhoek International Airport within 7 to 10 working days.
Our CNC systems support ISO G-code standard programming. Users can import DXF or CAD drawings directly into our programming interface. This allows operators to adjust roller paths, feed rates, and rotational speeds, enabling rapid transitions from high-volume production to small-batch prototyping for custom replacement parts.
