A method of bonding a thermoplastic polymer tube to a thermoplastic polymer article to form a fluid flow passage therethrough comprises inserting the tube 11 into a channel extending through the article from a first side thereof so that the tube protrudes through and beyond the second side of the article 1, inserting a metal rod 14 into the tube 11 so that the metal rod 14 protrudes beyond the tube on the second side of the article, and contacting the tube protruding beyond the article with an elongated sealing element 7 having an axial recess in the tip thereof. The axial recess is adapted to accommodate the metal rod in sliding engagement. The sealing element is moved towards the second side of the article, melting the thermoplastic polymers of the tube and article and forcing the polymer 16 into recessed and bevelled sections of the article channel. In preferred embodiments, the sealing element is an ultrasonic sound sealing element. <IMAGE> |
