Abstract
A die for a press system. The die may include a stamper and a housing, having a cavity disposed therein, coupled to the stamper. The die may also include a gasket disposed within the cavity. The gasket may be coupled to the stamper at a position above a workpiece to be imprinted by the stamper.
Claims26
A press system, comprising:
- an upper die and a lower die, at least one of the upper and lower dies comprising:
- a stamper;
- a housing, having a cavity disposed therein, coupled to the stamper;
- a first gasket disposed within the cavity of the housing;
- a second gasket disposed within the cavity of the housing, the second gasket disposed above a position to contain a workpiece to be imprinted by the press system;
- and
- a support member disposed between the stamper of the at least one of the upper and lower dies and the other one of the dies, the support member configured to reside around an outer perimeter of the workpiece.

A press system, comprising:
- an upper die and a lower die, at least one of the upper and lower dies comprising:
- a stamper;
- a housing, having a cavity disposed therein, coupled to the stamper;
- a first gasket disposed within the cavity of the housing;
- and
- a support member disposed between the stamper of the at least one of the upper and lower dies and the other one of the dies, the support member configured to reside around an outer perimeter of a workpiece to be imprinted by the press system, wherein the first gasket is disposed above the support member, wherein the first gasket is disposed at a first distance of approximately 2 millimeters from an outer perimeter edge of the workpiece, wherein the at least one of the upper and lower dies further comprises:
- a second gasket disposed within the cavity of the housing, the second gasket disposed above an inner perimeter edge of the workpiece.
