  • Publication number: 20210354762
    Abstract: A cowl cross bar assembly with a reduced weight and an increased stiffness and a method of manufacturing a pipe of the cowl cross bar assembly. The cowl cross bar assembly includes a pipe disposed laterally inside a chassis and a winding material which is wound at different winding ratios around a surface of a first section of the pipe which needs stiffness and a surface of a second section of the pipe which needs flexibility. The method includes transferring, by a transfer device, a pipe disposed laterally inside a chassis to a winding device and winding, by the winding device, a winding material around only a surface of a section of the pipe which needs stiffness.

  • Publication number: 20210163072
    Abstract: The present invention relates to a hybrid cowl cross bar manufactured through an improved method of performing an insert injection molding without applying hydraulic pressure to the inside of a metal pipe during injection molding in order to simplify a manufacturing process of a hybrid cowl cross bar and to secure rigidity of the cowl cross bar. According to an aspect of the present invention, a reinforcing material is inserted into a metal pipe that is a material of a cowl cross bar. The metal pipe may be made of a material such as aluminum, magnesium, or steel, like a conventional cowl cross bar. The reinforcing material may be manufactured by extruding a synthetic resin or a composite material (for example, PP+GF50%). A rib may be formed inside the reinforcing material to increase a capability to resist injection pressure when the metal pipe is insert-injected and to secure rigidity.
