In the forging process of automobile door hinges, there are generally a series of processes such as blanking, heating, pre-forging, precision forging, forming, and trimming. During the forging and heating process, induction furnace generated oxide scale will be produced. If the oxide scale is not removed, it will not only waste raw materials, increase costs, but also affect the accuracy, quality and appearance of the product. Brands like Mercedes-Benz and BMW have very high requirements for product hardness, precision, and appearance, and there must be no flaws. In the past, the door hinges were forged had oxide scale pits on the surface, which required manual polishing, which not only wasted time, but also had low efficiency. When customer starts to use oxide scale cleaning machine, because the surface quality of forgings has been greatly improved orders became more and more prosperous.The forge scale cleaning machine developed by us has been used in the Chinese market for six years and has helped many forging manufacturers improve the surface quality of forging products.
