Extrusions are a manufacturing method that involves pushing or pulling a material through a die to create a shape. Synonyms for extrusions include profiles, shapes, molds, forms, castings, and channels. Profiles are commonly used in construction for window and door frames, while shapes can be used for anything from automotive parts to kitchen utensils. Molds are often used in the creation of plastic and metal products, while forms are used in the creation of concrete structures. Castings are typically used in the production of metal components, and channels are used in the distribution of fluids or electricity. Regardless of the specific terminology used, extrusions are a critical component of modern manufacturing.
