A mold is a hollow container used to give shape to a material, often in the process of manufacturing. It can be made from various materials, including metal, plastic, or silicone, and is designed to create a specific form when a substance, such as plastic, metal, or concrete, is poured or pressed into it. Once the material hardens or sets, the mold is removed, revealing the shaped object. Molds are widely used in industries like construction, automotive, and food production. They allow for the mass production of identical items, ensuring consistency and efficiency. Different types of molds, such as injection molds and blow molds, serve specific purposes depending on the material and desired shape.
