The pressing method is to pour granular or flaky explosives into a mold, and apply pressure through a punch on a press to press the loose explosives into a column with a certain shape, size, and strength.

[0003] For large-sized molds for pressing explosive columns, two-way pressing is often adopted. The mold is divided into an upper punch, a lower punch, and a middle mold. Due to the large diameter of the column, the weight of the mold is often relatively heavy, and it cannot be manually carried, installed, or disassembled, and mechanical equipment needs to be used for assistance.
