What is metal extrusion processing?
Metal extrusions processing is an important method of pressure processing using the principle of metal plastic forming. Metal ingots are processed into tubes, rods, T-shaped, L-shaped and other profiles at one time through extrusion.
Metal extrusion press is the most important equipment to realize metal extrusion processing Extrusion is one of the main methods for the production of non-ferrous metals and stainless steel materials and the forming and processing of parts.
It is also an important method for the preparation and processing of advanced materials such as various composite materials and powder materials.
From the hot extrusion of large-size metal ingots, the hot extrusion of large pipe and rod profiles to the cold extrusion of small precision parts, the direct solidification and molding of composite materials from powder and pellets to intermetallic compounds, For difficult-to-process materials such as superconducting materials, modern extrusion technology is widely used.
Classification of extruded aluminum
According to the metal plastic flow direction, extrusion can be divided into the following categories:
Positive extrusion:
During production, the direction of metal flow is the same as that of the punch
Back extrusion:
During production, the direction of metal flow is opposite to that of the punch
Compound extrusion:
During production, the flow direction of a part of the blank is the same as that of the punch, and the other part of the metal flows in the opposite direction of the punch.
Radial extrusion:
During production, the direction of metal flow is 90 degrees to the direction of movement of the punch.
