Extrude is a transitive verb that refers to the act or process of pushing, forcing, or shaping a substance or material, usually in a semi-liquid or plastic state, through a specific opening or die to create a desired shape or form. This technique is commonly used in manufacturing and engineering processes.
When a material is extruded, it is typically subjected to pressure and temperature to make it more malleable. It is then fed into a machine called an extruder, which contains a screw mechanism that propels the substance through a specially designed nozzle or die. The die has an opening with a predefined shape, such as a tube, rod, or profile. As the material is forced through the die, it takes on the shape of the opening, resulting in a continuous length of the formed product.
Extrusion is widely employed in various industries, including plastics, metalworking, and food processing. Plastic pipes, rods, and films are often produced through extrusion, as are metal profiles and shapes. In the food industry, extrusion is commonly utilized to create items such as pasta, snacks, and breakfast cereals.
The term "extrude" can also be used figuratively to describe the process of forcing something out or projecting it forcefully. For instance, a volcano may extrude molten lava, or a machine can extrude liquid material into a mold to form a specific shape.
In summary, extrude is the action of pushing or shaping a material through a die or opening to create a continuous length of a desired shape or form.
