Abstract: A system and method of painting parts of large dimensions that present a certain amount of flexibility that makes their shape geometrically unstable in the event of being moved. The surface of a part is moved in front of a paint spray device by an arm of a robot, while the spray device remains stationary relative to the robot and while the part is being deformed. Other elements include a gripper for gripping parts of large dimensions, the gripper being adapted to implement the method; an installation; and a booth for performing surface treatment of parts.

Abstract: The invention relates to a method of fastening first and second thermoplastic parts of a motor vehicle, the first part having a protuberance projecting from a face and the second part having an engagement surface, the method consisting in bringing the second part into contact with the face of the first part, in heating the protuberance, and in plastically deforming the protuberance towards the second part so that the second part is gripped between the face of the first part and an end portion of the protuberance.
