Profilherstellung

Profilherstellung, also known as profile extrusion or simply extrusion, is a manufacturing process used to create objects of a fixed cross-sectional profile. The process involves forcing a material, typically molten plastic or metal, through a die of the desired cross-section. As the material exits the die, it cools and solidifies, retaining the shape of the die. This method is highly versatile and can produce a wide range of shapes, including simple bars, complex hollow sections, and intricate designs.

The primary advantage of profilherstellung is its ability to produce continuous lengths of uniform cross-section efficiently. The die acts as a mold, ensuring consistency in the product. Different materials can be extruded, including various plastics like PVC, polyethylene, and polypropylene, as well as metals such as aluminum and brass. The specific properties of the extruded profile are determined by the material used, the die design, and the extrusion parameters such as temperature and pressure.

Applications for extruded profiles are widespread. They are commonly found in construction for window frames, door frames, and trim. In the automotive industry, they are used for sealing, trim, and structural components. Other uses include furniture components, electrical insulation, and consumer goods. The ability to customize the profile shape and material makes profilherstellung a valuable manufacturing technique for a diverse array of industries.
