Extrusion machines are industrial systems used to shape materials by forcing them through a die to create continuous profiles. This process is widely used in manufacturing industries to produce products with a fixed cross-sectional shape, such as pipes, sheets, films, and wires.
The concept of extrusion exists to enable efficient, high-volume production of uniform products. By applying pressure and heat, materials such as plastics, metals, and food ingredients can be transformed into desired shapes with consistency. This makes extrusion one of the most reliable and scalable manufacturing methods used globally.
Extrusion machines typically consist of a hopper, barrel, screw mechanism, heating elements, and a die. The raw material is fed into the machine, melted or softened, and then pushed through a die to form the final shape.
