Hot metal is the one that is forged by pressing and molding while cold metal is casted
Hot metal is a process in which the metal is heated to a high temperature and then cooled rapidly, causing it to contract violently as it cools, resulting in a coiled shape. This process can be used to create objects with complex shapes, such as chains or machine parts
Cold metal casting involves pouring molten metal into a mold and allowing it to cool rapidly to solidify it. This method of manufacturing can be used to form many types of products, including statues and jewelry.
