Abstract: A press is provided for simultaneously pressing and piercing an object. The piercing means moves from a sheathed to unsheathed position in response to compressive pressure. The piercing means are normally biased in the sheathed position by a bias means. Methods and apparatus for piercing an object are disclosed. The press can be used to produce a pierced dispensing device having a compression coating by (a) charging to a die mold a quantity of powder to be compressed; (b) delivering to the die mold an unpierced dispensing device core; (c) charging to the die mold an additional quantity of powder to be compressed; and (d) substantially simultaneously (i) compressing the elements within the die mold to produce a compression coating, and (ii) piercing the compression coating. The compression coating can comprise, for example, a loading dose or a semipermeable membrane.
