Matters needing attention in aluminum profile extrusion are mainly to keep the product size stable, the tolerance accurate and the surface free of scratches.

As long as these aspects are done well, there is basically no big problem.

Master Liu of Dongguan Aluminum Factory told me that in the process of extrusion, we should pay attention to the following problems.

First, pay attention to the temperature of the extrusion cylinder, not less than 470 degrees.

Second, the cooling bed should be replaced in time to avoid scratching the surface.

Third, the aging temperature should be controlled around 180.

Fourth, whether the aluminum profile is done well depends mainly on the production level of the mold.
