Kemet Share | Causes and Solutions of Bubbles on Aluminum Profile Surface
When the aluminum profile extrusion machine is pressurized, air will remain in the aluminum profile, resulting in bubbles in the interior and surface of the aluminum profile, resulting in defects that cannot be completely solved, making the aluminum profile become waste.
upsetting caused residual air. Only when the diameter of the cylinder containing the aluminum ingot is larger than the diameter of the column rod, the column rod can be put into the cylinder containing the aluminum ingot. After applying pressure to the column rod inside the aluminum ingot barrel to cause the column rod to expand to the diameter of the ingot barrel, the gas carried by
Solution: Use the correct oiling method and reduce the amount of oiling; Strengthen the training of pre-job operation technology for employees;
Solution: According to the tonnage of the extruder, set aside a reasonable residual thickness, and determine a reasonable aluminum rod with a reasonable rod length according to the process parameters such as the single weight of the profile and the number of discharge counts;
Solution: Reduce the size of the flat die welding chamber, reduce the die hole of the split die, and the distance from the single side of the extrusion cylinder is more than 5MM.
