The diameter of the extrusion cylinder is generally in the range of 150mm~300mm.5252 aluminum extrusion tool operating temperature is 360℃~460℃, extrusion rate is 20m/min~80m/min. Extrusion special tools mainly include mold shell. Extrusion die is divided into flat die, split die, 2219 aluminum tongue die and separate component die according to the structural characteristics. Aluminum door and window profiles commonly used flat die and separate component die. The discharging table receives the extruded profiles from the extruder and connects the profiles to the discharging table. Discharging table is mostly horizontal bar transport aircraft, its horizontal bar fitness movement efficiency and extrusion rate with step. Step motor beam type is commonly seen in the roller table, and a very large number of centrifugal fans are installed below to ensure that the profile is symmetrical and refrigerated, so that the temperature of the profile is less than 70℃ before straightening. The support force straightening machine contains twisted crankshaft rod, which can be straightened while turning and calibration. The supporting force straightening hot pressing is the storage platform, which feeds profiles to the CNC sawing machine table, and the CNC sawing machine saws off profiles according to the fixed size.
