ekstruuderitud

Extruded refers to a process used to create objects of a fixed cross-sectional profile. A metal is pushed through a die of the desired cross-section. Extrusion may be done with the metal heated to reduce the force required for deformation, making it easier to work. The process of extrusion is similar to drawing or pressing wire. Extruded products are found in everything from window frames and door frames to car parts and electrical conductors.

The extrusion process typically involves heating the raw material, often a metal or plastic, to a temperature where it becomes pliable but not molten. This heated material is then forced under high pressure through a shaped die. The die has an opening that precisely matches the desired cross-sectional shape of the final product. As the material is pushed through the die, it takes on that specific shape, and the continuous strand is then cooled and cut to the required lengths.

There are several types of extrusion, including hot extrusion, where the material is heated above its recrystallization temperature, and cold extrusion, performed at or near room temperature. Cold extrusion often results in a stronger and more precise product, while hot extrusion allows for more complex shapes and the processing of materials with higher melting points. The specific method chosen depends on the material being processed and the desired properties of the final product. This versatile manufacturing technique is widely employed across various industries due to its efficiency and ability to produce intricate and uniform shapes.
