Claims7
A method for retrofitting a pellet die system to form a multi-chamber pellet die system comprising;
- modifying an existing die body by:
- forming additional cavities in the existing die body to create at least one additional void body in the existing die body wherein at least one anvil and at least one plunger engage to form the additional void body;
- defining a step-down within each void body within the existing die body wherein the step down is contiguous with a portion of an interior wall and the step-down is formed below and substantially adjacent to an opening wherein the at least one plunger enters into a loading chamber and defined by a first ledge positioned at an angle with respect to the interior wall of the loading chamber wherein the first ledge contacts and guides the at least one plunger entering the loading chamber;
- and
- modifying an ejection base to accommodate each void body formed within the existing die body and to evacuate each void body.
