Aluminum coil is a metal production rolling by rolling machine, drag the corner, and cut by flying shears. Aluminum coil are widely used in electronics, packaging, construction, machinery, but in the manufacture of aluminum coil there will be some quality defects inevitably, so, what are the common quality defects of aluminum coil? Here we will explain them to you one by one. 1, the compound layer falls off: composite clad aluminum layer leave matrix falls off and form of the irregular defect. 2, embossing: due to strip crease, broken strip,roller surface irregular color difference periodically printed to the strip surface in the process of rolling. 3, waves, plate, strip various uneven phenomenon due to the non-uniform deformation of the floorboard, waves in the band edge of plate and strip are called edge waves, waves in the middle are called the middle waves, waves neither in the middle or edge are called the second rib waves, small size and assumes the circular wa...
