Abstract

Abstract Translated from German Verfahren zum Verbinden von thermoplastischen Kunststoffteilen, wobei deren zu verbindende thermoplastische Stirnbereiche durch Kontakt mit einem Heizelement, z. B. metallisches Schwert, insbesondere gleichzeitig bis zum Erweichen erhitzt werden, worauf die erweichten Kunststoffbereiche zum gegenseitigen Kontakt gebracht, insbesondere die Kunststoffteile zueinander geschoben werden, wodurch eine Schweißnaht zwischen den Kunststoffteilen gebildet wird, welche mechanisch beaufschlagt wird, wobei die noch erweichte und abkühlende Schweißnaht und gegebenenfalls die anschließenden Ränder der Kunststoffteile mit einem unter der Schmelztemperatur der zu verbindenden Kunststoffteile temperierten Druckelement impulsartig, insbesondere durch zumindest einen Impuls beaufschlagt wird. Method for connecting thermoplastic plastic parts, the thermoplastic end regions to be connected by contact with a heating element, for. B. metallic sword, in particular at the same time heated until softening, whereupon the softened plastic areas are brought into mutual contact, in particular the plastic parts are pushed towards one another, whereby a weld seam is formed between the plastic parts, which is acted upon mechanically, with the weld seam still softening and cooling and optionally the subsequent edges of the plastic parts are acted upon in a pulse-like manner, in particular by at least one pulse, with a pressure element tempered below the melting temperature of the plastic parts to be connected.
