Claim 0:
1. A process for making a metal core for a metal card, comprising the steps of:
locating a metal core in a reservoir in a process chamber, wherein the metal core is configured with at least one aperture located in a generally planar first surface area of the metal core;
introducing a two-part polymer mixture into the reservoir on top of the first surface of the metal core;
reducing a volume of voids contained in the partially-cured two-part polymer mixture held in the reservoir located in the process chamber by creating a partial vacuum in the process chamber followed by introducing a pressurized inert gas into the pressurized chamber;
removing the metal core with the partially-cured two-part polymer mixture from the process chamber;
allowing the metal core with the partially-cured two-part polymer mixture to cure outside of the process chamber to form a cured metal core; and
treating an upper surface of the cured metal core to reduce an amount of surface irregularities which are located in an upper plane of the upper surface.
