Etymology
the word extrusion originates from the latin verb extrudere, which is a compound of ex- ("out") and trudere ("to thrust, push"). this literal meaning of "thrusting out" was carried directly into the english term. the suffix -ion was added to form a noun describing the action or process. in modern technical and industrial contexts, the word retains this core logic, specifically denoting the manufacturing process of forcing a malleable material out through a die to create a shaped object.
