[0002] Friction material is widely used in multiple industries, and its shape is various. The friction plate used in electromagnetic brake is basically in the shape of a ring, which is made by pressing and processing powder friction material. If the ring-shaped friction plate is produced by dry process, there may be some problems. When directly hot-pressed, the flow of friction material in the viscous state is restricted due to the blockage of the middle mold core, resulting in uneven density distribution after pressing. To solve this problem, the current process is to produce by two-step method. First, the compression plastic is cold-pressed in the cold pressing mold to form a cold blank, and then the cold blank is put into the hot mold for hot pressing. However, the compression plastic also needs to be evenly distributed in the cold pressing mold during cold pressing.
