Extrusion Press (for Φ120mm Rod)

Copper Rod Extrusion Equipment, Brass Extrusion Press, Copper Extrusion System

When it comes to direct and indirect extrusion press, each has special features and benefits. In direct extrusion, the billet is driven forward by the ram, which will surely generate friction at the die and container wall. Thus, higher pressure will be required for direct extrusion.

In indirect extrusion, the billet is kept still and the ram is hollow. When processing, the extruded rod passes through the inner bore at a reverse direction to the movement of ram. The indirection extrusion cause no heat or friction however there is a limit on load applied.

Advantages of Indirect Extruders over Direct Extruder
1. No friction or heat.
2. 25%-30% extrusion force will be reduced.
3. Suitable for handling profiles with a small cross sectional area, under low temperature and at high speed.
4. Mechanically capable rods can be got thanks to uniform copper flow, small extrusion hole and low residual pressure.

Applications
Solar energy tubes, transformers, switch gears, to name a few.

Notes
1. Limited by the hollow raw, the applied load cannot exceed a certain range.
2. Limited by the size of die, profiles with complex cross section cannot be processed.
