    What is the casting process?

    Involves pouring molten metal into a mold to create a solidified product.

    What are the main steps in casting technology?

    Pattern making, mold making, pouring, cooling, removal, and inspection.

    How does sand casting differ from other casting methods?

    Uses sand molds, allowing for complex shapes but with lower accuracy.

    What are the advantages of sand casting?

    Can produce complex shapes and large parts with various metals.

    What are common disadvantages of sand casting?

    Poor accuracy, surface finish, and potential internal defects.

    What is a key feature of expendable molds?

    They are used only once for casting before being destroyed.

    What is the significance of core prints in sand casting?

    They ensure accurate positioning of cores within the mold.

    What happens during the cooling phase of casting?

    Molten metal solidifies in the shape of the mold cavity.

    What is the role of pattern plates in sand casting?

    They help align patterns and ensure proper mold formation.

    What is the purpose of using cores in casting?

    To create internal cavities in the final cast product.
