Aluminum extrusion press when the pressure will remain in the aluminum inside the air, resulting in internal and external aluminum appear bubbles, the occurrence of defects can not be completely resolved, making the aluminum into a waste. In order to prevent air from entering the aluminum profile, it is important to find out what causes the air to be carried.
Main Factors of Residual Air in Extruded Aluminum Profiles
Aluminum extrusion press when the pressure will remain in the aluminum inside the air, resulting in internal and external aluminum appear bubbles, the occurrence of defects can not be completely resolved, making the aluminum into a waste. In order to prevent air from entering the aluminum profile, it is important to find out what causes the air to be carried. The main factors for residual air inside the extruded aluminum profile include:
The long bar hot shear leads to residual air
For the long bar when the heat shear shear surface is absolutely not perfect, the vertical industrial aluminum simple rod thermal shear will make the rod bending is very serious, resulting in the aluminum section of the oval-shaped cross-section As well as being cut very large round fillet. Even if the latest type of long bar hot shear, the angle of the edge of the shear bar will always produce round, these round is the best place to stay in the air.
Upsetting leads to airborne residues
Only when the diameter of the cylinder containing the aluminum ingot is larger than the diameter of the rod. The rods can be put into the tube of aluminum ingots. After the pressure is applied to the rod inside the aluminum ingot barrel, the rod must be expanded to the diameter of the mandrel and the gas carried must be discharged. The gas does not emit in, and remains in the aluminum ingot and eventually becomes a bubble.
As a result of two aluminum rods connected to the residual air
Since the probability of the surface of the two stubs being substantially flat carried into the air is very small. The quality of sawing directly interferes with the amount of air carried between the two stubs. There is a high-tech to prevent the two short bar connected. To eliminate the possibility of air into the.
