How to Make Gold Bar

The casting of vacuum gold bar is usually done in a refinery because they usually need to produce gold bullion with very good surface quality and very bright. People usually prefer to buy such gold. When the refining is completed, the gold is placed in a granulator, through which it is made into small granules for weighing. Place the gold granules in the bar mold, and finally place the mold in the vacuum bar casting machine. Under the protection of vacuum and inert gas, it can avoid gold oxidation, shrinkage, and water ripples on the surface. After casting, place the gold nugget under the logo stamping machine to press out the required patterns and text. Then use dot peen marking machine to number the gold bars.

Step1: Preparation of Raw Materials
Selection of Gold: Choose high-quality gold raw materials, ensuring they meet the required purity and standards for the production of gold bars. Cleaning and Preparation: Clean the gold raw materials thoroughly to remove any impurities or contaminants.           This process is through the different forms of raw gold with metal atomization powder machine into powder, and then through purification technology to extract pure gold
Step2: Melting and Casting
Place the gold raw materials into a melting furnace and heat them using a high-temperature flame.     Control the temperature and melting time carefully to ensure complete melting of the gold without significant loss. The mold is customized according to the customer's requirements for the size and weight of the gold bar, and the gold solution is formed in the mold after stopping the heating.
Step3: Cooling
The graphite mold is placed in the cooled copper mold for rapid cooling, and the gold solution is cooled and solidified quickly.       The vacuum gold bar machine of Taeantech is protected by vacuum + inert gas in the melting and casting process, confirming that the surface of the gold bar is bright, no water ripple, no shrinkage, and no oxidation.
Step4: Marking
.Mark the gold bar with relevant information such as its purity, weight, and manufacturer's logo.    Use a permanent and clear marking method to ensure that the information is easily identifiable.   Marking is very important to verify the authenticity and quality of the gold bars
