Extrusion involves shaping materials like metals or plastics by forcing them through a die, primarily used in manufacturing large quantities of uniform profiles. Machinists operate machine tools to create precise parts from metal or other materials. While extrusion focuses on shaping bulk material, machinists refine or produce individual components. Both roles require technical skills, but extrusion emphasizes material handling and die setup, whereas machinists focus on precision machining and blueprint interpretation.
