There are different types of metal casting out there. They are specifically suitable for specific applications. The metal casting process is a manufacturing process in which metal is melted to be poured into a cavity. Casting has been done for ages, ever since the production of parts came into existence.
Metal casting can be typically used to produce a large variety of parts that are used in different industries. Different types of metal casting lead to the production of certain casting quality, complexity, properties, manufacturing cost, surface finish, dimensional accuracy, etc. All these properties are considered when selecting a suitable type of casting process for an item.
Today you’ll get to know the 4 common types of metal casting. Some of these casting processes are used for producing a certain type of item while, some are used to produce complex parts.
Types of metal casting
The common types of metal casting include sand casting, investment casting, die casting, and evaporative casting.
Sand casting
Sand casting processes are manufacturing process that uses sand to create a mold cavity. The sand serves as refractory material that can resist a molten metal. Greensand is usually implied because it has good binding properties, such as sand, clay, silica, and little amount of water. Pattern made of either wood or metal is used to create a good replica or model of the item to be produced, leaving the same shape in the mold cavity. Patterns are created to be slightly larger than the original item, to contract the molten metal during cooling.
