lämpöekstrusiota

Lämpöekstrusio, also known as thermal extrusion, is a manufacturing process where a material is forced through a die of a specific shape. This process is typically used for materials that are difficult to machine, such as metals and plastics. The material is heated to a temperature above its melting point or to a point where it becomes malleable, then subjected to high pressure, which pushes it through the die. This action shapes the material into a continuous profile.

The primary advantage of lämpöekstrusio is its ability to produce complex cross-sectional shapes with high precision and excellent surface finish. It is a highly efficient process for mass production, allowing for consistent and uniform product dimensions. Common applications include the creation of aluminum extrusions for window frames and automotive parts, as well as plastic profiles for various industries. The temperature and pressure are critical parameters that must be carefully controlled to achieve the desired material properties and dimensional accuracy. Different types of lämpöekstrusio exist, including hot extrusion, where the material is heated significantly, and cold extrusion, which is performed at or near room temperature but requires higher pressures. The choice of method depends on the material's characteristics and the desired final product.
