Aluminum extrusion is a metal plastic processing technology that forcibly pushes aluminum alloy billets through molds to form profiles with predetermined cross-sectional shapes. Similar to the process of squeezing toothpaste, the aluminum billet deforms in the mold and forms along the shape of the mold to obtain the desired profile. Extrusion aluminum profiles are extrusion process, which used for Fine Processing. Meanwhile, these products used 6063 in the Metals And Alloys, which can use Auto Parts. Moreover, we can provide the customized service according to your drawings, like cnc aluminum, custom aluminum extrusions, casting profiles and die cast metal. Aluminum profile extrusion utilizes the plasticity of metals. After heating the aluminum alloy billet to a certain temperature, it is placed in an extrusion cylinder and then subjected to tremendous pressure through a mold, causing the aluminum alloy billet to flow and form along the shape of the mold under the constraint of the mold.
