Aibang has earned high reputations in international market due to its high performance continuous rotary extrusion machinery for various non-ferrous metals. Our typical scope of supply is a complete production line which can complete processes such as rod payoff, straightening, continuous extrusion, cooling, drying, metering, and end product take-up.

Our range of continuous rotary extrusion line supports feedstocks such as copper, aluminum, and their alloys. It is a great solution to manufacture solid and hollow section products, including copper and aluminum conductor wires, trolley wires, busbars, strips, round tubes, multi-port tubes, and more. These extruded products are widely used for transformers, electric motors, switching devices, electric locomotives, as well as the evaporator and condenser units of refrigerators and air conditioners.

The continuous rotary extrusion equipment heats feedstock metals by use of friction. When deformation temperature is achieved, the metal will be able to be created into desired shapes with the help of extrusion dies and other tools.

In the course of rotary extruding, the extrusion wheel with groove continuously rotates. By means of the friction between the wheel groove and feedstock, the feedstock is continuously transported to the extruder, allowing extremely long end products to be created due to the unceasingly delivery movement. The development of such a process truly realizes the continuous production, so this technique has been widely employed.

As compared with conventional metal rolling and wire drawing technologies, continuous extrusion equipment has a great number of benefits.

• Shorter Process Flow and Lower Equipment Investment
  Continuous rotary extrusion machines can make the feedstock into desired shapes at a stroke, without the demand of ancillary equipment such as annealing furnace, heating equipment, acid pickling line, trimming machine, and more. While ensuring simplified production flow and reduced equipment investment, this also contributes to environmental protection.
• Lower Energy Consumption; Without Demand for External Heat Source
  In continuous extrusion process, the heat is generated via friction and deformation process. Thus, there is no need for additionally operations such as annealing and heating, which significantly cuts down energy consumption.
• Low Waste but High First Pass Yield
  Continuous extrusion machines won't produce wastes such as scrape edge, or residuals in the extrusion barrel. This ensures very high material utilization rate accordingly.
  Our range of continuous extrusion equipment for copper and aluminum products offers first pass yield up to 95% and 99%, respectively.
• Low Labor Intensity due to High Automation
  The entire continuous rotary extrusion line, characterized by computerized intelligent control, is in need of only two operators to conduct the production. The continuous extruding machine is suitable for manufacturing products of variable specifications by using different extrusion dies. Additionally, the extrusion dies can be changed in a fast and convenient way. Such a machine is great for forming products with a great variety of specifications.
• Consistent Product Quality
  The continuous extrusion for nonferrous metals is a plastic molding process conducted at high temperatures. This completely eliminates the internal defects of feeding metal materials. The employment of high quality extrusion die guarantees the optimal forming precision and satisfactory sectional shape when the product is extruded at high temperatures.
• Higher Electric Conductivity for End Products (such as wire, busbar, etc.)
  Through continuous rotary extrusion, crystalline grains of metal materials are rearranged, and the density of the feedstock is increased. This makes sure extruded copper and aluminum products have reduced resistivity and improved conductivity, even though the demand of annealing is eliminated.

All in all, continuous extrusion process is a revolution of traditional non-ferrous metal processing techniques. In addition to the advantages mentioned above, the continuous rotary extrusion process also have benefits such as: continuous extruding machines require smaller installation space, and the end product quality is superior to those made using traditional methods.
