Extrusion technology
  • Rough surface processing technology of aluminum profile
    Roughening is also a commonly used method in aluminum profile processing. According to the different states of rough surface, it can be divided into sand blasting surface and wire drawing surface, and there are corresponding processing methods: sand blasting and wire drawing; sand blasting and wire drawing have a longer history than sand blasting; the surface roughness can be divided into sand blasting surface and wire drawing surface;

  • Control and determination of extrusion speed in aluminum profile production
    The production practice shows that the influence of extrusion speed on different alloy aluminum profiles is different; the effect on 2 ×××, 7 ××× series aluminum profiles and 5 ××× series aluminum profiles with high magnesium content is the most intuitive and obvious

  • Determination and influence of extrusion deformation degree of aluminum profile
    The deformation degree determines the deformation uniformity of aluminum profile, that is to say, the uniformity of structural and mechanical properties of aluminum profile; generally, the deformation rate of extruded material is not less than 90% ~ 92%; if the deformation is too small, some casting structure may still be retained in the aluminum profile, so as to reduce the material properties;

  • Characteristics of metal flow in extrusion process of aluminum profile
    Aluminum profile extrusion is to force the metal to flow and deform under the action of external force; in the process of extrusion, the external force exerted on the billet is not uniform, so the flow deformation is not uniform, which will inevitably affect the differences in the structure, mechanical properties and size of aluminum profiles;

  • Aging treatment process of aluminum profile
    After quenching, the supersaturated solid solution in metastable state of aluminum profile has the tendency of decomposition and precipitation of excess solute. Under certain conditions, the heat treatment stage in which the supersaturated solid solution decomposes and precipitates is called aging
