    What are Castings & Forgings?

    Castings and forgings are two primary methods used in the manufacturing of metal components. Castings involve pouring molten metal into molds where it solidifies into the desired shape. Forgings involve shaping metal using localized compressive forces, often delivered by a hammer or a die.

    Definition of Castings & Forgings

    • Castings: The process of forming metal objects by pouring molten metal into a cavity or mold, where it solidifies.
    • Forgings: The process of forming metal parts by heating and applying pressure to deform it into the desired shape, typically to improve its strength and durability.

    Sub-Disciplines in Castings & Forgings

    • Alloy: Creating components from a mixture of metals or a metal and another element.
    • Aluminum: Specializing in lightweight and corrosion-resistant aluminum parts.
    • Carbon Steel: Forged or cast parts known for their strength and durability.
    • Cast Steel: Producing parts that combine the flexibility of steel with casting's design freedom.
    • Centrifugal Castings: A method where molten metal is poured into a rotating mold to create a cylindrical part.
    • Continuous Casting: Producing lengths of material by continuously pouring molten metal into a shaping mold.
    • Die Castings: Forcing molten metal under high pressure into molds, typically for intricate shapes.
    • Forged Aluminum: Aluminum parts created through forging for enhanced strength.
    • Investment Casting: Creating parts by casting metal into a mold created around a wax pattern, which is then melted away.
    • Lost Foam Castings: Using a foam pattern which evaporates upon contact with the molten metal.
    • Machining: The finishing process of shaping the forged or cast parts.
    • Plaster, Sand, Shell Molding: Various molding materials and techniques for creating the casting molds.

    Frequently Asked Questions: Castings & Forgings - Manufacture, Products, and Equipment

    What are castings and forgings?

    Castings and forgings are two primary processes used to shape metal into parts or components. Casting involves pouring molten metal into a mold where it solidifies into the desired shape. Forging involves heating metal until pliable and then using force to shape it, often with a hammer or press.

    How do the properties of cast and forged parts compare?

    Forged parts generally exhibit higher strength, fatigue resistance, and reliability than cast parts due to the refinement of their internal grain structure during forging. Cast parts, however, can be produced in more complex shapes and sizes, often at a lower cost due to less labor-intensive processes.

    What materials can be used in casting and forging processes?

    A wide range of metals can be used, including alloy steels, aluminum, carbon steel, cast iron, and non-ferrous metals. The choice of material depends on the required properties of the finished part, such as strength, weight, and corrosion resistance.

    What are some common applications of castings and forgings?

    These processes are used in a variety of industries, including automotive, aerospace, construction, and machinery manufacturing. Common applications include engine parts, gears, beams, levers, and other components requiring high strength or complexity.
