ال آلة البثق المستمر لمادة الألومنيوم (Conform process) converts pure aluminum or aluminum alloy rod feedstock (typically Φ9.5–15/20 mm) directly into finished tubes, flat wires, busbars, multiport tubes, sector conductors, and custom profiles in a single continuous operation. Friction between the rotating grooved extrusion wheel and the aluminum rod generates the necessary heat and pressure for plastic deformation, eliminating external billet preheating and intermediate annealing in most cases. Material utilization reaches 95–99 %, flash is limited to 1–3 %, product length is theoretically unlimited, and the output is normally soft temper suitable for direct take-up.
How Continuous Rotary Extrusion (Conform Process) Delivers Superior Results
Aluminum rod is paid off, straightened, cleaned (brushing or ultrasonic washing is common for aluminum to remove oxide), and fed into the circumferential groove of the rotating extrusion wheel. A coining roll and stationary shoe compact the material. Frictional shear raises the temperature into the plastic range; the abutment blocks further rotation and forces the aluminum into the die chamber, where it is extruded through a precision die. Online cooling, anti-oxidation treatment, metering, and dual take-up complete the line. The process supports both solid sections and hollow tubes (including multiport micro-channel tubes for heat exchangers) by changing the die and mandrel arrangement.
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.

Material Requirements and Process Notes
Feedstock is normally pure aluminum or soft aluminum alloy rod with yield strength ≤90 MPa and diameter tolerance ±0.2 mm. Oxide removal (brushing or ultrasonic cleaning) is essential for surface quality and die life. Cooling water capacity and controlled exit temperature determine final hardness and dimensional stability. Mechanical shoe locking, integrated hydraulic lubrication, PLC + HMI control, and optional online eddy-current flaw detection improve consistency and reduce operator dependency.
