Aluminum foil processing enterprise is a vital link, relating to a yield of aluminum prices and corporate profits point. The higher the yield, the greater the profits relative point. Of course, the yield of every step must be to control, standardize operations, but also sophisticated equipment and strong sense of responsibility of leadership, employees. Equipment and practices I do not know, can not find fault, I can only analyze the cutting knife according to practice it. Here I talk about slitting Why would Alice, multilateral, dusting.

Alice, multilateral, dusting problem removing material itself and the equipment problems, most of them associated with the blade. Typically, there are two main foil slitting blades. One is the circular blade, one is designated chip, also known as razor blades. Razor blade is a fixed point in the material winding passive cutting, cut open. Active aluminum foil cutting, faster, blade resistance is relatively smaller. Slower contrast. Blade thickness and corresponding resistance. Thicker blades, the greater the resistance. The thinner the opposite. Since the razor blade dicing is stationary, and the foil blade, when thin material contact point of tangency prone to fatigue, fever, so after some time will knife is not sharp, blunt knife will be tearing occurs dusting burr inevitable. Of course, these and cut angle are also related. Good selection of razor blades is the preferred solution to these problems, the ceramic blade should be preferred.

At present, all companies want to foil processing of high value-added cell foil, but cell foil acceptance criteria called harsh. Representative lithium battery company like: BYD, ATL, A123 batteries enterprises, acceptance criteria foil called harsh. Foil demanding, but also for the wide, dust, while Alice can be considered critical of harsh. So for yield is not high cell foil business, cutting the yield after processing is essential.
