Profiles

Technical profiles are essential in sectors such as mechanical and automotive engineering. This Lexicon section provides insights into types of profiles, materials, and production methods—ideal for accurately defining requirements in procurement.

• Extrusion

  The extrusion is a forming process which is mainly used for thermoplastics. The plastic is pressed through a shaping opening as a viscous mass under high pressure and high temperature. Extrusion is one of the most widely used processes in the plastics processing industry and, thanks to its wide range of advantages in terms of efficiency, has gained great importance in the production of plastic parts. An extruder is used for extrusion, which is also referred to as a screw press. In principle, a distinction is made between the single-screw extruder and the twin-screw extruder.

• Steel profiles

  Steel profiles are steel components which have the same cross-section over their entire length. Steel profiles are usually produced by rolling, drawing or pressing and are used as construction steel or for the production of rails, ladders or struts. When using steel profiles, it is crucial to tune the decisive material or component parameters to the application. It should be ensured that the static moment, the moment of resistance and the moment of inertia of the surface correspond to the load requirements of the respective application.

• Bar extrusion

  The extrusion is one of the pressure-forming and is used to manufacture metallic profiles with different geometries. The process is used in the metal processing industry and in the construction industry, inter alia, for the production of hollow profiles. The extrusion allows the user to produce metallic profiles also with complex shapes such as irregular prismatic profiles. The technology is distinguished in particular by a high cost-effectiveness compared to alternative methods at low unit numbers. The extrusion is mainly used for aluminum components, but also for other materials.
