Vibrationsschweissverfahren von Kunststoffteilen

摘要

A first molded body (61) comprises a joint area (63), a first regulating projection (64) and a first guide surface (65) connecting an internal side surface of the first regulating projection (64) to the joint area (63), and a second molded body (62) comprises a welding projection (66) constructed to be welded to the joint area (63) at a distal end thereof, a second regulating projection (67) constructed to closely confront the first regulating projection when vibration welding of the welding projection (66) to the joint area (63) is completed and a second guide surface connecting an external side surface of the welding projection to an internal side surface of the second regulating projection (67). Burrs produced during vibration welding of the welding projection (66) to the joint area (63) are guided by the first guide surface (65) toward the internal side surface of the second regulating projection (67) along the internal side surface of the first regulating projection (64), and then they are further guided by the second guide surface (68) toward the external side surface of the welding projection (66).
