(??? Aluminum extrusions Furniture )The most important issue is the control metal temperature of the ingot from the start of heating to the quenching must ensure that the extruded section does not precipitate soluble phase structure or presentation of precipitated from the solution in small particles. products and extrusion temperature depending on the size of the unit pressure during operation to adjust. Ingot temperature deformation zone is varied during the extrusion process, with the completion of the extrusion process, the temperature gradually increased deformation zone, and with the increase in extrusion speed increased. Therefore, in order to prevent extrusion of cracks, as the extrusion process for the deformation zone and the temperature rises, the extrusion rate should be decreased.
