Gold Ingot
Gold Ingots are manufactured by the freezing of a molten liquid in a mould. To manufacture gold ingots there are several steps. First, the mould makes the melt solid completely. Next, the shape and size of the mould is made to make it easier to handle the ingot and the processing. Lastly, the mould is created to help cut down on melt wastage and help in the removal of the gold ingot.
When most people think of gold ingots, they have a tendency to think of pirate treasure, or sunken Spanish Galleons from centuries past. Gold ingots are still very much in use today. An ingot is basically a small bar of gold. You can buy gold ingots as small as 1 gram, although other popular sizes are 2.5 grams, 5 grams and 10 grams of gold. With the price of gold soaring ever higher, many people have made a business out of buying and selling gold ingots. What makes this business so attractive is that it requires no special skills or training, just a desire to make money.
They are usually stored in Bank Vaults around the world and not moved around much although the ownership of them may be. As they are now worth around 200,000 to 300,000 US dollars, depending on the price of gold, they are not used very much by small investors who generally will buy and sell smaller bars within their price range.
The cost of manufacturing the smaller 1,2.5, 5 and 10 gram bars does not make them very good investments as a premium has to be paid and it would take some time, even with the current increases in gold value, to appreciate any profit from their purchase.
There are continuous casting methods for gold ingot processing that allows a stationary front of solidification to form by the continual take-off of cooled solid material, in turn adds an additional molten liquid to the to the process of the casting method.
