Industrial Profiles

The production of aluminum profiles is mainly achieved through the extrusion process, which is an efficient method of machining aluminum alloy materials into a specific cross-section shape. The following are the main steps and related details of aluminum profile production: Main steps Raw material preparation: Select suitable aluminum alloy as raw material. Different alloy components can meet different mechanical properties and use requirements. Before extrusion, it is usually necessary to heat the aluminum alloy rod to achieve the best plastic state. Mold design and manufacturing: According to the cross-section shape of the aluminum profile required to be produced, the corresponding mold is customized. The quality of the mold directly affects the quality and accuracy of the final product. Extrusion molding: The heated aluminum alloy is placed in the extrusion press and passed through the mold through strong pressure to form the required cross-section shape. This is the most critical part of the entire production process. Cooling and shaping: Newly extruded aluminum profiles need to be cooled quickly in order to fix their shape. This can be done by natural cooling or forced cooling (such as water cooling). The choice of cooling rate depends on the specific aluminum alloy type and its desired properties. Tensile straightening: In order to eliminate internal stress and ensure the straightness of the product, the cooled aluminum profile is usually stretched and straightened.
