Yokelink Metal Casting Sand Casting

Casting is a manufacturing process in which a liquid material is usually poured into a mold that contains a cavity of the desired shape and then allowed to solidify. The solidified part is also known as the casting, which is ejected or broken from the mold to complete the process. Casting materials are usually metals or various time-setting materials that harden after mixing two or more components together; examples are epoxy, concrete, plaster of Paris, and clay. Metal casting is a 7,000-year-old process used in both manufacturing and fine art. The first known cast object is a copper frog that dates back to 3200 BCE, found in present-day Iraq. During metal casting, molten metal is transferred from a crucible into a mold to create a positive metal cast object. The metal and mold are cooled, and the metal object is removed and finished. Traditional metal casting techniques include lost-wax casting, plaster mold casting, die casting, and sand casting, to name a few. These metal casting processes may be completed in a foundry or a jewelry studio. Metal casting processes have been known for thousands of years, and have been widely used for creating sculptures, jewelry, transportation, weapons, and tools. Casting is most commonly used to create complex shapes that would otherwise be difficult or uneconomical to make using other methods. Heavy equipment such as machine tool beds, ship propellers, etc. can be easily cast to the size required instead of having several small pi
