What are the differences between hollow aluminum profiles and solid aluminum profiles?

Update time : 2022-09-01 19:45:57

From the production process point of view, both hollow aluminum profiles and solid aluminum profiles are extruded after being heated by aluminum rods. The difference between the two lies in the use of different extrusion dies. What about the mold? The following will give you a brief introduction to the differences between the two aluminum profiles.

1. Hollow aluminum profile

The processing of hollow aluminum profiles generally uses a flat-split combined extrusion die, which is a die composed of an upper die and a lower die. The components of the upper die include shunt holes, mold cores, working belts and empty knives, etc. The components of the lower die include welding chambers, die holes, working belts and empty knives, etc. The main working principle is that the material enters the mold cavity from the shunt holes. Inside, use the shunt holes to distribute the aluminum alloy reasonably, and determine the size of the shunt holes according to the cross-sectional size of the aluminum profile. When extruding, the shunt holes should be slightly inclined outward to reduce the pressure in the cavity. The internal shape of the profile is mainly fixed by the die core, the height of the welding chamber to 10mm above, can make the die core to maintain stability, the split hole of aluminum alloy materials in the welding chamber, and then in the role of high temperature and high pressure flow from the die mouth.

2. Solid aluminum profile

When solid aluminum profiles are processed, they do not need upper and lower dies. It only needs to be processed on one die and then extruded. The extrusion die is relatively simple, although solid aluminum profiles are heavier than hollow aluminum profiles. Strong, but in real production, hollow aluminum profiles are more widely used than solid aluminum profiles.

Aluminum extrusion profile six places are required during the stretching process

Jul .07.2023

The aluminum extrusion profile must be cooled to below 50 degrees before stretching. If the temperature is too high, stretching will not only burn the human body, the hair belt, but also expose absolute waste products such as bending, twisting, and poor performance before and after aging, because the stress in the aluminum alloy profile can not be completely eliminated.

Curtain wall aluminum profile purchase mainly see where?

Appearance quality of curtain wall aluminum profile: the surface of anodic oxide film is not allowed to have electrical burns, oxide film falling off and other defects; Electrophoretic, powder, fluorocarbon profile paint film should be uniform, neat, smooth, do not allow wrinkles, cracks, bubbles, flow signs, inclusions and paint film fall off and other defects, but allow local film within 80 mm at the end of the profile.
