In the rapidly growing new energy, power transmission, and electrical equipment sectors, manufacturers need fast, flexible, and high-quality production of aluminum conductors. The RLB Aluminum Material Continuous Extrusion Machine (Conform-type continuous rotary extrusion line) offers a single-step solution that transforms Φ9.5 mm or Φ15 mm aluminum rods directly into soft aluminum tubes, porous flat tubes, strap wires, conductors, busbars, and complex profiles — eliminating the need for multiple drawing or annealing steps.
With a lengthened extrusion belt and specially heat-treated wheels, the line achieves full material compaction, uniform microstructure, and outstanding surface quality while maintaining low leakage (≤5 %) and high output. The soft extruded product allows direct bobbin take-up and optional online cutting saw integration, dramatically simplifying downstream processing.
Engineered for the booming new energy, power transmission, and electrical equipment sectors, the RLB Aluminum Continuous Extrusion Machine achieves full material compaction, uniform microstructure, outstanding surface quality, and excellent electrical conductivity while maintaining leakage ≤5 %. The lengthened extrusion belt and specially heat-treated wheel deliver higher throughput, lower energy consumption (10–20 % savings per ton), and superior product performance compared to traditional hydraulic extrusion methods.
How Continuous Rotary Extrusion (Conform Process) Delivers Superior Results
The RLB machine employs advanced continuous rotary extrusion (CRE / Conform) technology. Aluminum rod feedstock enters a precision-grooved rotating extrusion wheel. Friction and controlled pressure generate localized heat, bringing the material to a plastic state with dynamic recrystallization. The material then flows into the die chamber and exits as finished profile or tube of unlimited length in a single, continuous operation.
Key process advantages versus traditional batch or hydraulic extrusion:
- No preheating or post-extrusion annealing required for most soft aluminum products
- Superior microstructural uniformity and electrical conductivity
- Significantly lower energy consumption and higher material yield
- Compact footprint (up to 60 % smaller than conventional lines)
- Consistent dimensional accuracy and surface quality at high speeds
Energy-Efficient & Eco-Friendly Design
No preheating or annealing stage; integrated hydraulic system with zero oil leakage; constant-tension take-up and automatic caterpillar tractor reduce labor to a single operator. New-generation models achieve approximately 20 % energy savings per ton, up to 80 % higher production output and 60 % space savings compared with traditional hydraulic extrusion lines.
Premium Components & Smart Features
Mechanical locking of extrusion tooling ensures stable extrusion conditions. Upgraded high-quality Chinese gearbox, Siemens/ABB electrical controls, aviation plugs for rapid connection, and industrial cloud data system provide full production traceability and remote support capability.

Frequently Asked Questions
What is the main difference between continuous rotary extrusion and traditional aluminum extrusion presses?
Traditional presses are batch processes requiring billet heating, limited length and often multiple subsequent drawing/annealing steps. Conform lines provide true continuous production of unlimited lengths in a single step with lower energy use, smaller footprint and superior microstructural uniformity.
Which aluminum products can be produced on the Aluminum Continuous Extrusion Machine?
Round tubes, porous flat tubes (MPE), solid/strap conductors, busbars (flat or shaped), and complex custom profiles — all in soft temper suitable for direct take-up or further processing.
How much energy and space can I save compared with conventional lines?
New-generation RLB models typically achieve approximately 20 % energy savings per ton, up to 80 % higher production output and around 60 % reduction in floor space versus traditional hydraulic extrusion setups.
