Ekstrudoinnilla

Ekstrudoinnilla, a term derived from the English word "extrusion," refers to a manufacturing process used to create objects of a fixed cross-sectional profile. The material, typically a plastic or metal, is pushed through a die of the desired shape. This process is commonly employed to produce a wide range of items, including pipes, tubing, window frames, and even food products like pasta and cereal.

The extrusion process begins with the raw material, often in pellet or powder form, being fed into a heated barrel. Inside the barrel, a rotating screw mechanism melts and homogenizes the material, then forces it forward under high pressure. As the molten material exits the barrel, it is shaped by the die. After passing through the die, the extruded product is cooled, often by water or air, to solidify its shape. Finally, the continuous profile is cut to the desired length.

There are various types of extrusion, including hot extrusion and cold extrusion. Hot extrusion involves heating the material to a temperature above its recrystallization point, making it more malleable. Cold extrusion is performed at or near room temperature, which can result in increased material strength due to work hardening. The choice of method depends on the material properties and the desired final product characteristics. Ekstrudoinnilla is a versatile and efficient manufacturing technique, crucial for many industries.
