Molding is a manufacturing process that involves shaping materials, often using a hollowed-out block called a mold. This technique is commonly used with various substances, including plastics, metals, and ceramics. The material is heated until it becomes pliable, then poured or injected into the mold, where it cools and hardens into the desired shape. Molding is widely used in industries such as automotive, consumer goods, and construction. For example, plastic molding is essential for creating items like containers and toys, while metal casting is used to produce engine parts and machinery components. This process allows for efficient mass production of complex shapes.
