In metalworking, casting involves pouring liquid metal into a mold, which contains a hollow cavity of the desired shape, and then allowing it to cool and solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process. Casting is most often used for making complex shapes that would be difficult or uneconomical to make by other methods.

Casting processes have been known for thousands of years, and widely used for sculpture, especially in bronze, jewellery in precious metals, and weapons and tools. Traditional techniques include lost-wax casting, plaster mold casting and sand casting.

The modern casting process is subdivided into two main categories: expendable and non-expendable casting. It is further broken down by the mold material, such as sand or metal, and pouring method, such as gravity, vacuum, or low pressure.

In the performing arts industry, a casting (or casting call) is a pre-production process for selecting a certain type of actor, singer or dancer for a particular role or part in a script involving a dramatic production meant for an audience.

Casting is a manufacturing process using a fluid medium in a mould, so as to produce a casting.

• Casting (metalworking) is one notable variant of this, using molten metal.

Casting can also refer to:

• A process in sculpture of converting plastic materials into more solid form, prior to patination or other surface treatment
• Casting, Moulting or Shedding of hair in most breeds of dog and other mammals
• In bookkeeping, casting or footing is a method of summing a table of numbers by column (down)
• Casting (performing arts), a pre-production process for selecting a cast of actors and other talent for a live or recorded performance, or models for a photo shoot or showing
• Casting (fishing), the process whereby a bait, fly or lure is placed into or onto the water to catch fish
• Casting (falconry), anything given to a hawk to purge and cleanse its gorge

In angling, casting is the act of throwing bait or a lure using a fishing line out over the water using a flexible fishing rod. The usual technique is for the angler to quickly flick the rod from behind toward the water. The term may also be used for setting out a net.

There are several techniques anglers use to attempt to cast further, the most prominent of which is the shifting of body weight towards the front foot in correlation to the forward movement of the rod. That combined with stopping the fishing rod at 45 degree's and using the correct fishing tackle will help anglers cast further.

Casting is a manufacturing process in which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process. Casting materials are usually metals or various cold setting materials that cure after mixing two or more components together; examples are epoxy, concrete, plaster and clay. Casting is most often used for making complex shapes that would be otherwise difficult or uneconomical to make by other methods.

Casting is a 6000-year-old process. The oldest surviving casting is a copper frog from 3200 BC.
