DEMONSTRATIONS OF IMPERFECTIONS - Coil
Dishing —a coil with a wall that tapers toward one side instead of being perpendicular to the coil ID. Normally this occurs toward the end of large coils. Edge bead, edge build up —an excessive build up of paint on the edge of the strip. Fish eye —a round or elongated crater-type coating imperfection that may have a particle in the
How To Avoid Slit-in Coil Slitting
If the line is uneven or the break is rough, it is a bad edge. Some slitting problems can be attributed to poor metal quality; however, it is much more common for the problems to be caused by other variables and factors during the slitting process. Slitting encompasses many variables, and most of
Aluminum Surface Finishing Corrosion Causes And
Oct 17, 2021 A protective oxide film of aluminum is only stable in a pH range of 4.5 to 8.5. 1 Chemical operations for the metal surface of aluminum include many process solutions that intentionally exceed this pH range for cleaning, metal removal and subsequent smut removal. These process solutions are formulated to avoid deleterious pitting or preferential

Anodized Aluminum: 8 Things You NEED To
The electrochemical reaction causes pores to form on the surface of the aluminum as excess positive ions escape. These pores form a geometrically regular pattern and begin to erode down into the substrate. The aluminum at the surface combines with the negatively charged O 2 ions to create aluminum oxide. This is called a barrier layer, a

Coil-on-Plug Ignition: The Art Of COP Misfire Diagnosis
When an engine with coil-on-plug (COP) ignition starts to misfire, there are two challenges: finding out which cylinder is misfiring and finding out why. Even if you find a bad coil, simply replacing it is not the whole repair, because like so many other parts of a vehicle, COP ignition coils don’t really die, they’re murdered. We’ll discuss how and why later; first let’s focus on

What Are The Main Characteristics Of Color Coated Aluminum
3. Weather resistance, the pattern on the surface of the color-coated aluminum coil is a pattern made by high-temperature baking. The luster is very good, it can be maintained for a long time, the color is also very stable, the color difference will not change much, and it can generally be used for 20 years. None of the above will be bad.
