Abstract

PURPOSE: A method for manufacturing gold or silver bars is provided to improve the quality of the gold or silver bars and to enhance productivity and economical efficiency by simplifying the scale of a working environment and additional facilities. CONSTITUTION: A method for manufacturing gold or silver bars is as follows: After gold or silver liquid(110) poured in a mold(10) is dried and removed from the mold, the dried gold or silver liquid is left in a temporarily processed high-temperature state so that a standard bar(100) can be manufactured. Gold or silver band-type materials(210) pass through multiple rollers(20) to form card bars(200). The card bars are formed in the same shape as the shape of the standard bar. The card bars are arranged on the top and the bottom of the standard bar and then put into a jig(30). A press heated at high temperature presses the top and the bottom of the card bars attached to the standard bar so that the standard bar and the card bars can be integrated.
