Screw part e.g. nut, has base body, seal and safety device that are made from different polymer materials in multi-component injection molding method and are connected with one another, where safety device increases torque of screw part

摘要

The part (1) has a thread (3) arranged on a base body (2), and a peripheral seal i.e. O-ring, where the base body has a ring-shaped cross-section. A thread safety device (6) increases a floating torque of the screw part during manufacturing a screw connection of the screw part with a component. The base body, seal and the safety device are made from different polymer materials in a multi-component injection molding method and are connected with one another, where the base body is made from glass fiber, carbon fiber or aramide fiber.
