5 gram C.HAFNER Gold Bar

Minted  bars  refer  to  the  manufacturing  process  that  is  applied  to  create  them.  The  process begins  by  heating  gold  material  in  a furnace  until it  turns  to  a  molten  slurry.  During  the heating process, all unwanted impurities in the slurry are removed until only molten gold of high purity is left, most often at around 99.99%. The molten gold is then poured into moulds, usually in the shape of large bars, where it cools and solidifies. The solid gold is then inserted into  a  mill  that  rolls  the  gold  into  panels  with  a uniform  dimension.  Afterwards, the  gold panels are inserted into a blanking press that punches blanks out of the gold panels. The next step  involves  the  weighing  of  each gold  blank  to  ensure  that  it  is  neither  underweight  nor overweight and those that pass this test are then polished for them to obtain a shiny surface. The  last stage  involves the  minting  process where the  gold  blank  is  inserted into a  minting press  that  presses  its  die with  huge  force  to transfer  the  design  from  the  die  onto  the  gold blank. The result is a  minted bar. The newly  minted gold bar is then inspected before being sealed in a transparent tamper-proof protective package.
