soudage par friction

OBS: Principales applications [...] Feuillards plastiques, emballages de forme circulaire.
OBS: Bien que contesté entre autres par le Grand Dictionnaire Encyclopédique Larousse, le terme «soudure» est employé au sens de «soudage» (l'opération) par les auteurs de «L'emballage sous toutes ses facettes» (code : BEMBA, 1988), ouvrage piloté par le Laboratoire National d'Essais de France et la revue Emballages Magazine.

CONT: In friction sealing, the top and bottom halves of cylindrical containers may be easily joined. The bottom member is held against rotation by a friction brake; the top member is pressed against the bottom member and rotated. The heat generated by friction at the interface between the two halves melts their surfaces and the viscous interface causes the bottom half to rotate in unison with the upper half. This effects the seal.
OBS: Thermoplastics with surfaces that become slippery when heated are best suited to friction welding ...
