Process and apparatus for manufacturing a connection and stress transmission element by overinjection, and connection and stress transmission element

摘要

A connection and stress transmission element for automotive vehicle mechanisms, the apparatus and the process for manufacturing the joining element by overinjection. The joining element has a central portion (1) and a first end portion (2). The central portion (1) is of a material providing mechanical resistance and is bar-shaped, having a first end and a second end. The first end portion (2) is of plastic material overinjected on the first end such that the central portion (1) and the first end portion (2) form a single-piece joining element. The apparatus has: containing devices (100) to define a cavity (110) between the surface to be overinjected and the containing devices (100); input devices (200) and output deices (300) in the containing devices (100) so that the overinjection product is introduced in and extracted from the cavity (110).
