Patent Abstract

The method involves arranging two components (2, 3) together or on top of each other at an area (9) to be connected. A tool i.e. deformation-resistant joining tool (4), is penetrated into the two components by rotating around an axis (A). A joining tool is pressed on one of the components with pressure during penetrating process and is rotated with a rotation speed (Vrot) such that the other component is plastified in the area to be connected. The two components are designed as a metal component and a plastic component, respectively. The plastic component is made of fiber-reinforced plastic. Independent claims are also included for the following: (1) a deforming tool for deforming an edge of a sleeve (2) a tool for manufacturing a mixing assembly from two components.
