Instead of the usual practice of forcing the chemical plating solution through the tool continuously so that only part of the metal is depleted from the solution, the invention provides for forcing the solution into the interstices and retaining it there for a predetermined time sufficient, preferably, to chemically plate all of the metal from the solution onto the walls of the interstitial spaces of the tool. | |
