An extrusion die is a precision-engineered manufacturing tool used to shape raw materials?such as metal, plastic, or rubber?into continuous, uniform profiles. By forcing heated material through a specifically designed opening under immense pressure, the die dictates the final product's dimensions, surface finish, and mechanical properties.
Key Types of Extrusion Dies
Solid Dies: The simplest and most cost-effective type, used to create solid shapes like rods, bars, and structural beams.
Hollow Dies: More complex multi-piece assemblies (featuring bridges and a mandrel) used to produce hollow or perforated sections like pipes, tubing, and custom channels.
Flat/Sheet Dies: Specialized dies with a wide, flat slit opening used to produce plastic films, flat sheets, and industrial coatings.
