  • the invention comprises a method and a device for producing a plastic vehicle attachment and a plastic vehicle attachment and its use.
  • plastics In the wake of increasingly stringent regulations on carbon dioxide emissions from motor vehicles, there are strong efforts to reduce the weight of a vehicle and thus its fuel consumption. Constant advances in the field of plastics make it possible to replace large parts of the metal body with correspondingly lighter elements made of plastics, in particular polymeric materials. I ke parts or even the entire window area can be replaced by plastic elements (made of polymeric materials). These show in many cases at a significantly lower weight comparable hardness, stability and resilience as a steel body window. In addition, due to the weight reduction, the center of gravity of the vehicle is shifted further downwards, which has a positive influence on the driving behavior. In addition, plastics (especially polymeric materials) can be manufactured, processed and shaped at much lower temperatures than metals. This reduces the energy consumption and the costs of producing the materials.

  • Special high-performance plastics such as aramids or Kevlar have very high strengths and stabilities.
  • plastic material parts have to meet different requirements and functions. Important parameters here are the stability, fracture behavior, scratch resistance, impact resistance or notched impact strength. In addition to technical aspects such as weight and strength of the individual components, the shape, geometry and appearance play an increasingly important role. Especially in the automotive industry, apart from mechanical properties, features in the area of design and aesthetics are of great importance. To combine different features in plastics (polymeric materials), these are composed of differently shaped and differently procured base materials. Established processes for producing these materials include two or more component injection molding processes. In this way it is possible, features such as weather resistance, surface gloss and
