  • Publication number: 20180186085
    Abstract: The invention relates to a method for manufacturing a plastic pedelec frame (1) by, preferably integrally, joining two matching plastic half-shells (2, 3), said pedelec frame being provided with receptacles (12, 13, 14) for a handlebar (4), a bottom bracket (5) and preferably a seat (6). The two plastic half shells (2, 3) are made from a fiber-reinforced thermoplastic material containing a partially aromatic polyamide, using an injection molding process. The invention also relates to a pedelec frame (1) manufactured by said method.

  • Publication number: 20150308753
    Abstract: A method for producing a multilayered pipe line, in particular for transporting refrigerant in an air-conditioning system. First, an endless inner layer made of stainless steel having a layer thickness of at most 1 mm, preferably at most 0.5 mm, is provided, which constitutes the inside layer of the pipe line. Then, the endless inner layer is covered, by means of an extrusion process, with a plastic layer that preferably has a layer thickness of at most 7 mm, in particular at most 5 mm.

  • Publication number: 20060070870
    Abstract: A method for making the plastic profile comprising depositing an inner thin film with a metallic appearance onto the surface of the flexible extruded plastic profile depositing an outer protective cover layer that is at least partially transparent onto the inner thin film wherein the inner thin film and the outer protective cover layer form a layer system to cover the flexible extruded plastic profile.

  • Publication number: 20040151858
    Abstract: The invention relates to a flexible extruded plastic profile, especially a plastic tube, comprising an outer face that has a dyed and/or metallized appearance. The profile is further characterized in that to its exterior a layer system is applied which comprises an inner thin film having a metallic appearance and an outer, at least partially transparent protective layer. The invention further relates to a method for producing a flexible extruded plastic profile, especially a plastic tube. The inventive method is characterized by applying to the exterior of the profile an inner thin film that has a metallic appearance and, on top thereof, an outer, at least partially transparent protective layer, thereby producing a layer system.
