And the raw material zinc particles are manufactured by shearing a zinc plate through a forming die and punching. The reasonable design, material selection, manufacture and the like of the die directly influence the forming, quality, production efficiency and production cost of the raw material zinc particles, so the manufacture of the forming die is very important.
