It is more than 2 times of the speed of free forging hammer. In the study of high velocity compaction of iron powder,Phillips Screws Factory copper powder (FCu), soft magnetic materials in different processes and different companies, scientists get the expected regular patterns of density changes. With the increase of suppression and suppress pressure, the density is improved. The study found that the density increases rapidly with the suppression rate increase. When the density is more than 7.9m • s-1, the sl growing speed becomes slower.Compacting pressure by the static pressure into dynamic pressure, high velocity compaction powder body by the static pressure P and the role of the momentum mv, short duration of action, instantaneous impact force F = mv / t great, so that the density of [...]
