I believe that the aluminum plate enterprises, the common defects of aluminum plate is not very understanding, the following simple for you to introduce several common aluminum defects, so as not to cause unnecessary trouble for their own negligence to the enterprise. Harbin Dong Xing Aluminum Co., Ltd is a competent and reliable Aluminum sheet wholesales.

1, the shape of the plate:

(1): Cuoceng strip between the layers and irregular surface dislocation caused by uneven surface. The reasons are as follows: the blank is not smooth; the tension control of the uncoiling and coiling of the rolling mill is improper; the adjustment of the flattening roll is not proper.

(2) collapse: serious deformation of the coil core, coil shape is not round. Causes: improper tension during crimping; external force compression.
(3) lateral bending: showing plate shape to one side bending. Cause: leveling machine pressure is not enough.  Harbin Dong Xing Aluminum Co., Ltd could provide you with 2024 aluminum plate on sale.

(4) wave: aluminum plate, aluminum strip due to uneven deformation and the formation of a variety of uneven phenomenon of the general term. The wave produced by the plate and the edge is called the edge wave, and the wave produced in the middle is called the intermediate wave. The wave between the center and the edge is neither in the center nor on both sides. The wave is called the two rib wave, and the smaller and usually round wave is called the wave breaking. Causes: uneven roll gap adjustment, unreasonable roll shape control, uneven lubrication and cooling, uneven deformation of aluminum plate, unreasonable distribution of pass reduction.
