  • Method for joining a plastic workpiece to a further workplace
    Patent number: 9925720
    Abstract: A method that includes: arranging plastic and further workpieces (1, 3) such that an abutment surface (5) of the plastic workpiece (1) is abutted to a first surface (13) on the further workpiece (3) and a projection (7) on the plastic workpiece (1) extends through a through hole (17) in the further workpiece (3); linearly moving a friction tool (23) parallel to its rotational axis (25) such that a friction surface (31) on the tool (23) contacts a front surface (9) of the projection (7); linearly moving the tool (23) along the rotational axis (25) while rotating the tool (23) so that a pin (29) on the tool (23) penetrates and plasticizes the projection (7) as well as drives a portion of the plasticized projection (7) into an undercut (21) formed in the hole (17) of the further workpiece (3); and retracting the tool (23) from the projection (7).
