Castings can range in size from a few grams, like a cast ring, to thousands of pounds, like a diesel engine. The metal casting process has broad uses across manufacturing, especially in the development of technology and transportation industries. Casting is an inexpensive way to create complex shapes and designs and to easily create multiples of the same object. Throughout history, metal casting has been used to make tools, weapons, and religious objects. Many years later, metal casting technology boomed in the 20th century, developing processes that most modern methods are based on. Throughout history, the Middle East and West Africa both commonly utilized lost wax casting. Later, around 500 BCE, the Zhou Dynasty introduced iron casting. Around 1000 BCE, India was among the first ancient civilizations to cast silver and copper coins for currency. During the Shang Dynasty in China, single-use sand molds were first utilized for casting metals. Bronze was a much easier and stronger alloy to work with, compared to gold and was cast into tools and weapons using stone molds.
During the Bronze Age, metal casting exploded in popularity. The first known cast object is a copper frog that dates back to 3200 BCE, found in present-day Iraq. Metal casting processes have been known for thousands of years, and have been widely used for creating sculptures, jewelry, transportation, weapons, and tools. These metal casting processes may be completed in a foundry or a jewelry studio. Traditional metal casting techniques include lost-wax casting, plaster mold casting, die casting, and sand casting, to name a few. The metal and mold are cooled, and the metal object is removed and finished. During metal casting, molten metal is transferred from a crucible into a mold to create a positive metal cast object.
Metal casting is a 7,000-year-old process used in both manufacturing and fine art.
