The applications related to the heat of fusion can be seen very commonly in our daily life around us. Many of the popular household products are created using the heat of the fusion process, which can be seen in a variety of applications. The most common and easy example of use of the heat of fusion is the melting of ice into water form. The manufacturing industries are home to the many great majorities of examples of the heat of fusion that are in use. The following examples have been worked upon to make them perfect over hundreds of years and are still being worked on to be used today. The heat of fusion is a major requirement to perform the operation of coin production, glassblowing, forging metal items, and even in transforming blow moulded polymers into household products. The plastic Coke bottle from the vending machine, the change in your pocket, and the vase of glass on a fireplace mantle all have been created and went through a heat of fusion manufacturing process.
Copper and Solid Zinc, which are also the metals used in American pennies, are heated at a high temperature in a casting furnace until they attain the liquid phase using the heat of fusion method. The molten zinc and copper are then poured into a mould and are moulded into the shape of long bars once they have reached their liquid phase. The molten metal transforms from its liquid form to a solid-state throughout this process of casting, resulting in a solid bar. Heavy machinery is used which helps in flattening these long bars, which are then stamped over and are shaped into thousands of coins. A monetary system would not be easy and could not exist in the United States without the process of heat of fusion.
