Why is the surface of
Aluminum extrusion profiles easy to produce scratches ?
The specific reasons are as follows:
(1) shaking too much in the process of transportation, poor lining fixed.
(2) each operation process for the production (adhesion) of aluminum chips not timely treatment, is also the main cause of abrasions.
(3) saw cutting finished saw table, storage rack, frame profile, arranged crowded, lift and pull one of them, it is easy to cause mutual scratch, if there are edges and corners will cause profile line.
(4) double hole (porous) more than the die
Aluminum extrusion profiles, due to the speed of the die hole uneven, profile length is not uniform, the outlet under this high temperature is mutual abrade profiles, with a certain width sheet black white rough surface, the oxide profile abrade surface appears dark black, this is the extrusion waste.
(5) : the mold use time is too long, die cavity knife, supporting pad, special pad and other exit stuck to a large number of aluminum metal, profile flow diameter die cavity knife, supporting pad, special pad, so that the profile scratch.This is rarely the case.

The Aluminum extrusion profiles on the machine tools, sometimes on the shelf is not neat, or check profile will make it mutual friction, resulting in the profile sheet with tooth scratch, especially profile plane wider profile or curved arc profile, will cause the possibility of surface scratch more!
