BO-LJ300 Aluminum Continuous Extrusion Machine (Production Line)

The Conform-type process uses an annular-grooved extrusion wheel and compaction roller to feed aluminum rod continuously. Friction between the rod and wheel generates the heat and pressure needed for plastic deformation, eliminating the need for separate billet preheating furnaces and enabling genuinely non-stop production.

A single machine covers flat bus bars (4–32 mm wide, 1–10 mm thick), round tubes (Φ6–20 mm, wall ≥ 0.7 mm), and custom cross-sections up to 150 mm² — all changed over by replacing the extrusion die and chamber. This lets operators serve multiple product lines without additional capital equipment.

With a surplus material rate of only 1–3%, nearly all feedstock converts to saleable product. For factories processing aluminum at scale, even a single percentage-point improvement in yield translates directly to lower unit cost.

Every station from rod pay-off through dual take-up is engineered as a coordinated system. The straightening and cleaning unit prepares the rod surface for reliable grip in the extrusion wheel groove, while the tension and metering device ensures dimensional consistency before coiling. A unified electrical control system manages the entire line from one operator panel.

The ribbed cast base and segmented main body are built to absorb the continuous high-torque loads inherent in friction extrusion. The integrated lubrication, hydraulic, and internal cooling circuits keep operating temperatures and wear within service limits, supporting sustained multi-shift production.
