The Common Quality Problem of aluminium door supplier

Aluminium profile can be made lots of aluminium profile products by casting, extrusion, and other surface treatment, like anodizing, electrophoresis, powder coating and PVDF. Aluminium profile can make lots of products, like aluminium window, aluminium door, aluminium curtain wall, metro cylinder manifold profile, container board, vessel profile, aluminium heatsink, aluminium channel, aluminium pipe, aluminium bar, aluminium tube and so on.

Aluminium is the third most abundant element in the earth crust. It makes up 7.45% of the earth crust after oxygen and silicon and it’s the most abundant metal. Aluminium profile is one of nonferrous metal, which has wide application. Aluminium profile is mainly made of 92% pure aluminium ingot. In order to enhance strength, hardness, wear resistance, aluminium profile will be mixed carbon, magnesium, silicon, sulfur to compose “aluminium alloy”.

1.Aluminium profile has widely use. Now, Xingfa Aluminium, Top 1 aluminium profile manufacturer in China, helps you to find the cause of common quality problem.
2.Pull Trail: it is caused by the temperature and extrusion speed of aluminium ingot.
3.Scratch: it is caused by the graphite in discharge hole,the abrasion of roller and belt.
4.Bend: it is caused by the temperature and strength of stretch.
5.Deformation:it is caused by the broken of mould or lacking of spacer block in the process of extrusion stretch.
6.Low Hardness: it is caused by the temperature of aluminium ingot, the speed of cooling and the alloy.
7.Burr: it is caused by the low temperature of aluminium ingot, the poor quality of aluminium ingot and the long using time of mould.
