There are several extrusion methods that are most widely used for aluminum channel profiles processing:
1. Positive extrusion method
2. Reverse extrusion method
3. Pipe extrusion method
4. Continuous extrusion method
The positive extrusion method is the most basic extrusion method. With its mature technology, simple process operation and high production flexibility, excellent surface products can be obtained.
The feature of positive extrusion is the relative sliding between the billet and the extrusion cylinder during extrusion, and there is a large external friction, and in most cases, this friction is harmful, it makes the metal flow unevenly, thus giving The quality of the extruded product has an adverse effect, resulting in uneven tissue properties of the head and tail of the extruded product, the surface part and the center part, which increases the energy consumption of extrusion.
Under normal circumstances, the friction energy consumption on the inner surface of the extrusion cylinder accounts for 30%-40% of the extrusion energy consumption, or even higher. The increase in speed accelerates the wear of the extrusion die.
The above is the explanation of the processing method of aluminum channel profiles, I hope it can be helpful to everyone.
